Fluoride and teeth. Where a large amount of fluoride can enter the human body - we study products, hygiene products and environmental factors. What effect does it have on the condition of the body as a whole?

Today is a hot topic: .

Fluoride is one of the health industry's biggest lies.

Almost every tube of toothpaste states that it contains fluoride. It is said to help keep your teeth healthy and protect you from tooth decay. History, as they say, is silent about the fact that if a child accidentally eats a tube of toothpaste and dies immediately, as well as why this actually happens...

How harmful is fluoride?

My daughter goes to kindergarten, where parents very often parent meetings They are discussing which toothpaste to brush children’s teeth with or without fluoride, and they repeatedly touch on the topic of the harm of fluoride in toothpaste.

For me this topic was somehow not particularly important. I even chuckled inadvertently, saying that people no longer have problems thinking about such unimportant things, until I came across certain information about dangers of fluoride in toothpaste.

And the ball began to unwind more and more...

From new information my hair is gradually standing on end, and once again I feel deceived again by this “health industry”.

Before we talk about the dangers of fluoride in toothpaste, let's first understand what fluoride is.

Because fluorine and fluorine are different.

So, what are fluoride and fluorite?

The dangers of fluoride in toothpaste - facts

Fluoride is a fluorine ion.Fluorine is a gas, and in nature it is most often found in compounds with other substances, for example calcium fluoride (CaF) or sodium fluoride (NaF).

You and I consume fluoride from products such as onions, lentils, almonds, nuts, greens leafy vegetables . But - and here ATTENTION!

Fluoride, which is added to toothpaste, drinking water, some tablets and salt, does not contain essential microelement fluorine NOTHING IN COMMON! On the contrary, this fluoride is a very poisonous chemical by-product aluminum, steel and phosphate industry!

Remember this please! Because there is more than enough deception about fluoride!

And why? And in general, where did this so-called fluoridation of teeth come from?

How did it all start?

The “fluoridated wave” came to us from America somewhere in the 50s. As already mentioned, fluoride is a by-product of the aluminum, steel and phosphate industry. As a dangerous poison (and fluoride is even more dangerous than lead and arsenic!), it had to be somehow safely eliminated, for which a lot of money was spent. But “scientists” from the beauty and health industry came to the aid of this industry. And so, poisonous garbage not only began to be disposed of elegantly, but also crazy money began to be made from it.

“Fluoridation is the biggest deception of this millennium.” Robert Carton, Ph.D. 1992

Harm of fluoride in toothpaste:

• fluoride was used in both world wars as a gaseous agent
• Sodium fluoride is found in high concentrations in rat poison and some pesticides
• in not large quantities It is found in toothpaste, mouthwash and tap water (not available in all countries)
• fluoride can accumulate in the human body, thereby causing gradual but sure poisoning
• accumulating in the body, fluoride kills vital enzymes that are responsible for the functioning of the immune, digestive, respiratory and circulatory systems
• fluoride slowly but surely disables a person's free will, which is why it is found in 60% of psychosamotic medications

“Fluoride causes cancer faster and more powerfully than any other chemical.” Dr. Dan Bark, one of the founders of the American Institute for Cancer Research.

What about the teeth?

I don’t think you’ve ever heard about the dangers of fluoride in toothpaste from your dentist? And this is not surprising. Doctors are the same people; they often cooperate with various big brands and offer what is beneficial to them.

They simply have no reason to talk about the dangers of fluoride in toothpaste.

What is fluorine and what properties does it have?

Fluorine is Chemical substance, belonging to the group of halogens (symbol F, atomic number 9). It is a non-metal and pure form at normal conditions the environment is in a gaseous state, the molecule consists of two atoms, the pairs have Strong smell and pale yellow color. Fluorine is distinguished by the fact that it is the most active electronegative substance, while being poisonous and capable of causing chemical burns upon contact with human skin. Fluorine actively interacts with other chemical elements, creating new substances and compounds.

IN Everyday life we come across this substance when eating food, water, using toothpaste, etc. In human skeleton fluoride is in the form of ions, it strengthens bones, making them stronger. When you consume large amounts of fluoride, it accumulates, bones become brittle, and stains caused by fluorosis may appear on your teeth. Fluorosis is observed most often in areas where its concentration is drinking water exceeds 10 ppm.

In its pure form, fluorine is dangerous for humans; when it interacts with water, it forms hydrofluoric acid, which penetrates tissue and destroys calcium compounds in bones. At the same time, fluorides have a number of useful and irreplaceable properties for humans that protect their health.

How is fluoride used in dentistry?

IN modern dentistry fluorine is actively used in the form of fluorides, compounds of fluorine with other elements that are harmless to humans. They help prevent dental caries. Fluorides, interacting with tooth enamel, form compounds that prevent acids from penetrating into the more vulnerable layers of the tooth. An environment negative for the development of microbes is also created, and the exchange of proteins and minerals in bones and teeth is restored. To prevent caries, dentists recommend fluoridated water, rinsing with a fluoride solution, using toothpaste with fluoride, applying gels to teeth, coating teeth with fluoride varnish, and taking medications in the form of tablets. All recommendations are assigned in individually depending on the state of the patient’s living environment and his health.

Fluoridation of teeth in dentistry is a common procedure that has proven itself as effective remedy for the prevention of caries. Fluoride varnish has a viscous structure that allows the substance to remain on the teeth for up to several hours. This time is necessary for fluorides to attach to the enamel and form a stable connection with it. The drug is applied to the surface of the teeth, dried cotton swab, without touching the mucous membrane, is held for 4-5 minutes. After the procedure it is recommended only liquid food, no need to brush your teeth.

With deep fluoridation, the teeth are completely dried and the mucous membrane is isolated. The drug is rubbed into the teeth with massaging movements and remains for several minutes. During deep treatment, teeth are saturated with microelements and minerals. In this case, before fluoridation, it is necessary to clean your teeth and remove all tartar.

Pros of fluoride

1. Fluoride prevents microbes from attaching to the enamel surface, therefore, tartar does not form, which is the main cause of tooth decay.
2. Fluoride helps break down carbohydrates, which form acid that destroys enamel.
3. Fluorine forms the compound fluorapatite, which is responsible for the permeability of enamel, making it more resistant to acids.
4. Fluoride prevents the proliferation of microbes in the oral cavity.
5. Fluoride interacts with calcium ions, making teeth denser and strengthening the dental structure.

Cons of fluoride

1. An excess of fluoride leads to fluorosis, makes teeth speckled, they lose their natural flexibility and elasticity, and become brittle.
2. An excess of sodium fluoride negatively affects the nervous and circulatory system. It is more often found in toothpastes and gels. Patients with kidney disease or diabetes mellitus It is recommended to use pastes and gels as recommended by specialists and not to exceed the norm.
3. Excess fluoride negatively affects work thyroid gland. The toxicity of the substance can lead to a decrease in immunity, which will make a person more vulnerable to various diseases.
4. Symptoms of excess fluoride can include increased fatigue, dryness and pale skin.

How to compensate for the lack of fluoride in the body?

Fluorine is indispensable for humans and is part of the body's cells. Maintaining the balance of this substance is important for health. If there is a deficiency, fluoride can be replenished by drinking fluoridated water, using toothpaste or gels and medical supplies for the prevention of caries. Dental procedures effectively compensate for the lack of fluoride in tooth enamel. Before using this or that product, consult with a specialist to determine the form of the drug and dosage that is suitable for you.

When caring for the oral cavity, any consumer expects certain qualities from toothpaste. This cleaning product should effectively clean the dentition from bacteria and soft coating, strengthen enamel, prevent caries, freshen breath. However, the pastes differ in their composition. Let's try to figure it out: are they all equally useful? And is fluoride really necessary in them, about which so much good and bad is written in various dental articles.

Why is fluoride in toothpaste?

In general, fluorine, as they say, “in its pure form” is a gas poisonous to all living things. However, its harmless compounds are found in the most different products nutrition. For example, in apples and green tea. In addition, this same element is literally necessary for human bones and teeth.

Is fluoride in toothpaste harmful? The opinion of dentists on this matter is clear: fluoride is necessary in oral care. This is also confirmed clinical trials. Humans need fluoride, and in fairly large quantities. And in order for toothpaste to harm your health, you have to eat the toothpaste. And there are many. Or get a job at some factory where you breathe fluorine compounds day and night without using a respirator.

Why is fluoride in toothpaste at all? Its compounds have been proven to prevent oral bacteria from destroying tooth enamel. They also actively fight caries, which begins in individual, most demineralized areas. And if, fearing fluoride, you use oral care products without it or other active ingredients, harmful microorganisms will begin to actively multiply, and the enamel will weaken.

The benefits and harms of fluoride for oral care

However, there are also contraindications for the use of fluoride-containing toothpastes and powders. This is fluorosis - a congenital or acquired excess of fluoride in a particular organism. But this systemic disease occurs infrequently, and in all other cases no one is prohibited from brushing their teeth with fluoride-containing products.

True, pastes and powders containing fluorine may not be used in regions where this compound is used for processing domestic water for the purpose of bacterial purification. And then you need to find out at the local SES exactly how much fluoride it contains tap water. Because it is unlikely that there is so much substance there that an additional amount from a teeth-cleaning product can be decisive.

Summarizing the above, it can be argued that toothpastes with fluoride are recommended for use to strengthen tooth enamel in adults. For example, New Pearl Fluorine toothpaste with sodium monofluorophosphate and calcium carbonate from Nevskaya Cosmetics JSC, which:

• increases resistance to acid attack;
• helps strengthen and mineralize the top layer of tooth enamel;
• qualitatively removes soft plaque;
• carries out caries prevention;
• prevents the development of bacteria.

Fluoride in children's toothpastes

While everything is more or less clear with the presence of fluoride in “adult” toothpastes, parents of children have a lot of questions regarding children’s cleaning products. How much fluoride do children need? Is it harmful or beneficial to them? Should children include fluoride toothpastes in their regular oral care?

The opinion of dentists on this matter is clear: fluoride is necessary for children's teeth. It protects their enamel from bacteria. However, you need to monitor the age-related fluoride content in these products:

• up to 3 years, a value of up to 200 ppm is considered the norm;
• from 3 to 8 years - 500 ppm;
• from 8 years - up to 1500 ppm.

Responsible toothpaste manufacturers always take this indicator into account when giving age recommendations for their products. In addition, the fluoride content is indicated as a percentage on the packaging of oral hygiene products. Thus, for children, starting from 3 years of age, the toothpaste “Children’s Pearls Magic Fruits” (ppm 500) from JSC “Nevskaya Kosmetika” is recommended, which:

• strengthens the enamel of children's teeth;
• increases the resistance of the dentition to aggressive acid attack;
• significantly reduces the risk of caries;
• replenishes calcium deficiency;
• cleans teeth efficiently;
• Removes soft plaque as carefully as possible;
• has a pleasant and fresh fruit aroma;
• contains an optimal amount of fluoride for small children;
• does not contain sugar, triclosan, or peroxide.

Thus, we can conclude that:

• the benefits or harms of fluoride contained in a particular toothpaste directly depend on how exactly and in what quantities, as well as with what water the cleaning product is used;
• effectively external application fluoride (direct impact on the dentition), and by taking the substance exclusively in food (as part of some products), the fluoride deficiency in the enamel cannot be compensated;
• Fluoride-containing toothpastes are recommended to strengthen tooth enamel for both adults and children, but it is necessary to control the ppm value of the oral care product.

Is fluoride good for teeth?

Any sane person considers it necessary to brush his teeth every day. Most are also interested in which toothpastes are most effective in combating caries, focusing mainly on commercials and recommendations from dentists. It is generally accepted that toothpaste should contain fluoride, but has anyone ever wondered what this substance is and how it is useful? fluoride for teeth ?

Is fluoride good for teeth: it seems to be beneficial

Fluorine – chemical element, gas Supplements recommended by doctors are fluoride. It is known that the destruction of tooth enamel is caused by waste products of bacteria that infest oral cavity. These bacteria feed on sugar remaining in the mouth after eating sweet foods. Fluorides are destructive to bacteria, so they protect teeth from decay. Before fluoride was added to toothpastes, some countries began the practice of fluoridating water to prevent tooth decay.

Is fluoride good for teeth: or is it harmful?

But nowhere is it advertised that fluoride is a powerful poison! Its toxicity is even higher than that of lead. Just think about it - an average tube of fluoridated toothpaste is enough to kill a child. And, if you use such a paste for a long time, the toxic substance accumulates in the body. In this case, first of all, a person’s ability to think, connected speech, and memory deteriorates. In fact, toothpaste makes us stupid!

Is fluoride good for teeth: it’s all about money, as always...

And the reason why toothpaste containing fluoride began to be promoted is banal and involves a lot of money. The fact is that fluorides are waste from metallurgical production. In America in the 50-60s of the last century, an avalanche of claims from workers who undermined their health from negative impact fluorine To somehow protect yourself from paying compensation, the mighty of the world they convinced the doctors to “find” this beneficial features fluorine And for those, in turn, it was not difficult to direct dentists to promote fluoride-containing toothpastes.

When buying a tube of new toothpaste, you need to not only think about how to whiten your teeth, or pay attention to pleasant aroma. It’s worth looking at its composition. And to protect against caries you just need to follow some simple rules. If you eat sweets or drink sweet drink– then they should act on the teeth for as little time as possible. Afterwards, rinse your mouth with water, or better yet, brush and floss.

1. do not keep the paste in your mouth for longer than the prescribed two to three minutes, do not swallow
2. Watch how your children brush their teeth, so that there is no more than a “pea-sized amount” of paste on the brush, so that children do not eat the paste just like that (as often happened with my little one :)
3. take medications with fluoride only after consulting a doctor and carefully weighing the pros and cons

• Lavera- there are two of them, the one that is regular, non-bleaching, without fluoride
• Weleda- all without fluoride
• Logona- all without fluoride

“Fluoride, which is flavored with toothpaste, drinking water, some tablets and salt, has NOTHING IN COMMON with the essential microelement fluoride! »

Fluorine compounds have nothing in common with fluorine. “Atomic-molecular theory is for suckers!” (c) Do you think lentils contain pure fluorine? You are mistaken - also in the form of fluorides. The same ones as in pasta.
The only confirmed danger is fluorosis, and even then - an adult needs LARGE daily doses of fluoride - from 6 mg/l of fluid consumed - to get it. This will not happen from fluoridated toothpaste alone - you also have to, say, live next to a hydrofluoric acid production facility, or near a volcano, or in an area with very high content fluoride in water... (The story is different with children, they are much more susceptible to fluorosis, so it makes sense for them to use toothpastes without fluoride.) Other horror stories have not been confirmed by anything serious.
And about baiting rats and chemical weapon- so this, excuse me, is a purely manipulative argument. If you drink 14 liters of water at a time, you will also die, let's count the water on this basis dangerous poison. In small doses, fluoride is beneficial for teeth, and American statistics on caries speak very much in favor of fluoridation.

Based on this logic, then neither nicotine, nor alcohol, nor antibiotics harm a person if he consumes them little by little;)))

But there is no benefit from alcohol with nicotine, so its absence is easy to cope with. The same cannot be said about fluoride. I had a situation where I moved from an area where the fluoride content in the water is normal to an area where it is low (where the water supply is from surface sources). And I still had the usual pastas - without fluoride, and apparently there wasn’t enough of it from food. By the time I figured out what was going on, I managed to become a regular client of the dentist :)
It is incorrect to put antibiotics on a par with alcohol and tobacco; they have saved more than one life. Naturally, you should not use them thoughtlessly and without medical supervision.

I have similar situation. A couple of years ago, I read horror stories about the dangers of toothpaste with fluoride, and the whole family switched to bioactive toothpaste without fluoride. The result is that after 1.5 - 2 years my teeth began to fly out (I never had any problems with my teeth before) and the child (5 years old) had almost all of his teeth damaged to one degree or another! And it happened somehow at once, almost simultaneously all the teeth deteriorated. And this despite the fact that we always carefully monitor our teeth and almost never eat sweets. Our dentist was in shock, the little one’s holes were growing by leaps and bounds, we didn’t have time to patch them up, and when I found out what kind of tooth we were. We use toothpaste, she said to get rid of it, such a tooth. The pastes, he says, are still suitable for Moscow, but for our region - definitely not.

This is weird. In Germany, our water is not fluoridated; we have been living without fluoride for at least 5 years; no one has any problems with their teeth at all. And I always get compliments from the dentist about how good and healthy my teeth are.

For many years I regularly coated my teeth with fluoride varnish and used fluoride toothpastes - everything was fine (at 32 I have one filling). For the last three months after reading this article, I have been using Logona toothpastes without fluoride and as a result I have developed dental hypersensitivity (enamel hyperesthesia). And this is a wild pain while brushing your teeth, a reaction to sweets and cold, especially in the cervical area. I switched back to Lacalut (with fluoride), bought Rocks enamel remineralization gel (without fluoride, but with the right combination of minerals) - painful sensations disappeared in 2 days. So, people, use your head, not everything is so simple! You can find it directly on the Internet opposing opinions, and each of them will be supported by compelling facts and research results. The question “Who to believe?” on many problems remains open, especially if non-specialists are discussing it. For me the main factor here was personal experience! Perhaps such pastes are suitable for someone, but obviously not for me.

But you may also have tooth hypersensitivity if you have fluoride toothpaste. Any dentist will confirm this to you. Logon's pastes just didn't suit you.

Fluoride is included in many toothpastes and is widely used to prevent caries. Scientific research they say that if you regularly brush your teeth with such a paste, the likelihood of developing caries is reduced by half. This would be great news if it weren’t for the heated controversy surrounding the topic “Fluoride: benefits and harm?”, which divided people into two camps.

Some believe that fluoride in toothpaste is a poison that can cause serious illnesses. Others consider such rumors to be nothing more than a myth. Let's try to understand this issue.

Fluoride: a beneficial component or a dangerous poison for teeth

Fluoride is known as a trace element that we need for healthy teeth and bones. We have it in bone tissue and tooth enamel, and enters the body along with drinking water and some products.

Products containing fluoride:

• buckwheat, rice;

  corn;

• mackerel;

  veal.

Lack of fluoride in the body leads to the development of caries, anemia and osteoporosis. Although a person needs it in very small quantities, this does not make it less important for health. Fluoride makes teeth stronger, is involved in metabolism and is needed for the absorption of iron.

However, food products are not as effective at preventing tooth decay as fluoride toothpaste. This is why toothpastes with this mineral have become so popular among manufacturers.

Benefits of fluoride

How does fluoride protect our teeth? To begin with, it is worth mentioning that fluorine in its pure form can cause serious violations in the human body. Toothpaste uses its safe compounds - fluorides. The world learned about their benefits for dental health at the beginning of the 20th century, and the first fluoride-containing toothpaste appeared in 1914.

Fluoride ions (fluorides) restore tooth enamel, making teeth stronger and less susceptible to damage and acids. They remineralize damaged areas of the tooth at the stage early caries, thereby preventing its further development.

Fluoride content in toothpaste ppm (in parts per million)

All manufacturers must indicate the amount of fluoride in the toothpaste. For daily use Pastes with a fluorine content of 1450-1650 ppm are considered safe.

Fluoride is no less important for children's teeth. The most important rule when using toothpaste is that your child can spit it out and not swallow it. If he has already learned this, then he can safely choose a fluoride-containing toothpaste. For children's toothpastes, the following standards exist:

up to 4 years - 200 ppm;

from 4 to 8 years - 500 ppm;

from 8 to 14 years - 1400 ppm.

The harm of fluoride

If there is a lot of fluoride in the body, this can lead to intoxication, metabolic disorders, damage to the central nervous system, nausea, vomiting and fluorosis.

On the Internet you can find a list of other diseases such as autism and cretinism. However, there is no scientific data confirming the effect of fluoride on the occurrence of these diseases.

Most often, people are afraid of the development of fluorosis due to excess fluoride in the body. It can be congenital (formed during pregnancy of the mother, who should consume 2-2.5 mg/l of fluoride per day) or acquired (at a fluoride production plant).

Food or toothpaste does not contain that much fluoride.

For fluoride to cause serious harm to the human body, it is necessary to work in an aluminum smelter without observing safety precautions. A longer-term solution is to regularly swallow several tubes of fluoride toothpaste per day.

“Fluoride is harmful to teeth! In every tube of toothpaste there is an invisible danger - waste from aluminum production", "in every toothpaste with fluoride - lethal dose toxins! or “CNN admits that fluoride damages the brain and lowers IQ.” Have you already watched these videos, were horrified and have been “actively searching” ever since? No, not in such a search, but in search of pasta for sensitive teeth without fluoride?!

Before answering the question: is fluoride-free toothpaste good or bad, let’s define the concepts. ATTENTION: fluorine and fluorides are not the same thing! Fluorine is very poisonous as it is a reactive gas. Fluorides are not a reactive element, keyword- octane Any toothpaste allowed on the market does not exceed the permissible fluoride limits.

Without fluoride against caries? Hm…

Let's figure out how caries forms and start with the composition of tooth enamel. Most of tooth enamel is the mineral hydroxylapatite. This is an impure form of hydroxyapatite, which does not mean dirty teeth; from a chemical point of view, it is an impure compound. In order to better understand all this, you need to remember what a mineral is. A mineral is a salt or a compound of ions, like sodium chloride = table salt or calcium carbonate = scale on a kitchen faucet. Hydroxylapatite also consists of several ions: calcium, phosphate and hydroxide, which together form a crystalline chain. Sometimes other ions come to visit this crystalline chain, for example, carbonate or fluoride ions. In other words, even in such a strong material as a mineral, ions can replace each other.

Once again: our teeth are a mineral that consists of ions.

How does caries form?

Our teeth are covered in biofilm, more commonly referred to as plaque. It is home to millions of microorganisms. They are very happy when we eat carbohydrates and especially sugar, which they digest and at the same time release acid, as a result of which the pH in the oral cavity drops. What does falling pH mean for our teeth? Exactly the same thing that happens with scale (calcium carbonate) on a kitchen faucet: it is insidious in that it does not dissolve with water. BUT! Not if we treat the scale with acidic agents, such as vinegar or citric acid. Their low pH causes the mineral to dissolve!

The same thing happens to our teeth, which leads to the formation of a hole in the tooth - voila! Caries!

Tooth decay means that our teeth begin to dissolve. You can also say what is happening is DEMINERALIZATION. So, how can we overcome tooth decay? With the help of REMINERALIZATION! Everything is logical and simple!

OK! And how does this happen?

Let's remember our unclean hydroxylapatite. The purer the mineral, the more stable its crystal chain and the more difficult it is to destroy. And this is exactly what we want to prevent – ​​the destruction of tooth enamel! Small ions that mix in a crystalline chain usually disrupt its structure. Exception: fluoride ions! The fluoride ion is very small; if it takes the place of a hydroxide in a crystalline chain, then the entire chain becomes significantly denser. In the presence of small amounts of fluoride ions, fluorapatite or hydroxyfluorapatite is formed, which is much more stable than hydroxylapatite!

Fluorapatite – remains strong in acid!

Hydroxyapatite is destroyed!

That is, while fluoride ions are in saliva or in dental plaque, they can penetrate the apatite structure and thereby slow down the destruction of enamel or completely prevent it = REMINERALIZATION! The tooth has the ability to recover.

Let's say this is true! But surely there is an alternative to fluorides???

This destruction is not observed during the formation of fluorapatite. And the picture emerges again:

No fluorapatite - caries!

There is fluorapatite - healthy enamel!

These are the arguments of the analysis chemical processes, but what if in practice everything looks completely different?

Let's take a closer look at the information from the manufacturer of fluoride-free pastes. Who is interested? scientific evidence when they became much more significant alternative sources information revealing worldwide conspiracies directed against humanity! And who should we trust more here: some incomprehensible scientists or network worms who very carefully analyze various studies and draw brilliant conclusions?! The answer is obvious! Who studied what...

And yet, just in case, let’s look at the official sources of what science says about the benefits of fluoride for teeth: the use of fluoride in toothpastes is safe, the effectiveness is scientifically substantiated and confirmed! The positive effect of fluoride on teeth is obvious and is unanimously recognized by dental institutes and independent communities around the world.

But today there is no recognized clinical basis that could prove the ability of hydroskilapatite to replace fluorides, which is why the products are not prohibited for use, but are not considered clinically sound. This does not mean that the use of products with hydroxyapatite is useless: there are studies confirming its positive effect, but against caries - no! There is no protection against caries! In a word, the most main question remains open, and the tooth is doomed.

Of course, there are other means of remineralizing teeth. “Why use fluorides? After all, this is poison,” they shout from all sides.

Uh... Like all the elements chemical table. Any element is poison, only the quantity makes it poisonous or beneficial. When you yourself start to analyze whether it is possible to brush your teeth with fluoride pastes and you study dark side fluorides, pay attention to 2 things:

• concentration;
• in what form is fluoride added (toothpaste, drinking water, table salt, gels, etc.).

The critical dose is 5 mg of fluoride, that is, the only dangerous situation is when small children with low weight eat a large number of toothpaste. It is for this reason that the concentration of fluoride in children's toothpaste is 2.5 times lower (the market average).

At high consumption fluoride may cause increased fluoride in the teeth, or fluarosis, as an experienced YouTube viewer will notice. This danger does not come from fluoride in toothpaste! Never! Not in any case!

The permissible level of fluoride in toothpastes is set for effectiveness, but it is completely safe, non-critical = USEFUL, as it protects against caries!

By the way, which is typical, almost no toothpaste containing hydroxyapatite contains fluorides. Anyone who understands the principle of action of fluorides in the oral cavity will not find it difficult to guess why?! That's it! The question itself is brewing: if fluorine particles are bound into a hydroxyapatite matrix, then how to fit 2 elements that begin to interact with each other in one tube of toothpaste, so that this adhesion does not occur inside the tube and thereby the anti-carious effect becomes absolutely useless for use in the oral cavity ?

To do this, it is necessary to isolate fluorides in such a way that they are released only upon contact with saliva. This requires a clinical basis and development. The patent for fluoride catalyst technology is held by miradent®, and a product that contains 30% hydroxyapatite and at the same time 1450 ppm fluorides is called Mirasensitive hap. This tooth cream, which has an anti-caries effect, is extremely high concentration Hydroxylapatite, also potassium citrate, is a mild analgesic that reduces pain. At the same time, this cream remains affordable for most people.

How and with what you brush your teeth is your own business! Your teeth! To your health! Our task was only to explain the relationship. Now you understand the topic a little deeper, draw your own conclusions.

In order to understand how well schoolchildren brush their teeth and what toothpastes they use, we decided to conduct a survey. To do this, we have printed questionnaires with the most interesting questions. 3 “B”, 4 “B”, 2 “B”, 3 “A” classes took part in the survey. Having processed the results, we came to the conclusion that 76 students answered the questions in this way.

1) How many times a day do you brush your teeth? 1 time a day - 56%, 2 times a day - 40%, do not clean - 4%.

2). How long do you brush your teeth? 3 min.-25%, 2 min.-42%, 1 min.-33%.

3). How often do you change your toothbrushes? Less than once a year - 17%, 1 rub. At 3 months -62%, 1 rub. Per year - 21%.

4). How do you visit the dentist? 1 rub. At 6 months - 8%, 1 rub. Per year - 56%, do not attend - 36%.

Based on the results of the survey, it was clear that students do not pay enough attention to their teeth (Appendix No. 1)

We believe more needs to be spread about how to better protect and preserve teeth. In this regard, we decided to find out which toothpaste more effectively protects tooth enamel and conducted an experiment. Before the experiment, we conducted a survey of what toothpastes the students of our school use; 32 people were interviewed. Survey results:

Aquafresh -8 people, Lacalut - 3 people, Colgate - 11 people, Blend-a-med -10 people.

In container No. 1 we put an egg treated with Colgate paste, No. 2 - Blend-a-med, No. 3 - Aquafresh, No. 4 - Lacalut, added a 1% vinegar solution and began to observe. On the second day of the experiment, small cracks appeared on the eggs in containers No. 1 and No. 3, but no changes were observed in No. 2 and No. 4. Our photographs show that on the sixth day of the experiment, eggs No. 1, No. 2, No. 3 were deformed and the shell became soft, and no changes were observed in No. 4 either.

Conclusion:

More effective protection Lacalut toothpaste helps your teeth enamel. Other toothpastes provide less effective protection.

After the work we had done, we decided to approach our school’s chemistry teacher Marina Mikhailovna with a question; “Is it possible to chemically determine the amount of fluoride in toothpastes?” Marina Mikhailovna explained that this was possible and scheduled us a day for the experiment. We found out that by adding silver ions to a solution with toothpaste, the amount of fluoride in toothpastes. The results of the school experiment coincided with those at home.

In this connection, we recommend Lacalut toothpaste among all the listed toothpastes to the students of our school.

5. Conclusions.

According to the results of our study, Lacalut toothpaste provides more effective protection of tooth enamel. Other toothpastes (Aquafresh, Colgate, Blend-a-med) provide less effective protection. The results of the school experiment coincided with those at home. In this connection, we recommend Lacalut toothpaste among all the listed toothpastes for the students of our school. Our hypothesis that fluoride is very beneficial for teeth was confirmed.

We made a video about treating children with teeth, prepared a presentation on the topic “How to properly care for teeth,” and spent class hours in the classes of those who participated in the survey. We also compiled recommendations (Appendix No. 4) and a guide “How to properly care for your teeth”, 1 copy was donated to the school library

Project materials were used on class hour“How to properly care for your teeth” with presentation. They can be used in lessons, parent meetings, and offer information to the newspaper.

From the above, we can draw appropriate conclusions, which indicate that almost all serious manufacturers offer very wide choose toothpastes, and the choice is already ours, or rather our material capabilities, since the variation in product prices is serious. Therefore, this topic can be extended to many more pages, but all that remains to be said is that we still need to pay more attention to these issues and then our smile will be healthy.

Appendix No. 2.

The structure of the tooth.

A tooth is a hard substance
containing calcium and fluorine.

Most of the visible surface of the tooth is covered with enamel.

Tooth enamel is the hardest substance found in the human body.

Enamel is 95% mineral.

Appendix No. 3.

- Fluorine is a chemical element that small quantity brings to the human body great benefit.

- Fluorine protects teeth from caries and strengthens enamel.

- Fluorides These are fluoride compounds found in toothpastes.

Connections fluoride very similar in structure to the minerals from which our teeth and bones are built .

Reasons for dental fluoridation:

Fluoride preparations are necessary for the remineralization of tooth enamel;

Under the influence of fluorides, pathogenic bacteria stop multiplying.

Types of fluoridation:

Simple

Glubokoe

Sources of fluoride:

Fluoridated water

Food and drinks: fish, cereals, tea, yolk chicken egg, liver, fluoridated salt, dairy products

Choose fluoridated toothpastes;

Brush your teeth twice a day;

Change your toothbrush once every two months;

There are foods that are good for dental health: fresh vegetables, fruits, dairy products.

Do not alternate hot and cold foods:

tooth enamel may crack;

Eat less sweets;

Do not chew nuts, candies and others;

solid products;

At least once every 6 months;

visit the dentist...
