Chemistry research project “Which is better: paste or powder?”

Oral hygiene is important!

And the first thing that daily oral hygiene is associated with today is brushing your teeth.

and, of course, toothpaste. Although quite recently our grandmothers used dental cleaning powder. With the advent of toothpaste, the powder was forgotten. And now supporters of the powder method of brushing teeth are again appearing.

And here is the dilemma: what is healthier, tooth powder or toothpaste

?

The debate between supporters of one and the other method has been going on for a long time. Everyone defends their opinion.

From TV we hear every day about effective toothpastes, but almost no advertising for tooth powder. And this does not mean that the powder is ineffective.

Tooth powder or toothpaste - the choice is yours. But be sure to consult your dentist.

Purpose

It should be noted that at that time the purpose of tooth powder was not to prevent caries or treat periodontitis. At that time they did not even know such words, did not understand the reasons for their occurrence, and therefore could not yet contain these diseases with hygienic means. The main and only goal was to cleanse the teeth of plaque and tartar. Please note: in the first half of the 20th century, dentists had not yet performed such a now widespread procedure as professional oral hygiene. Neither ultrasonic nor air-abrasive (Air-Flow) treatment had yet been invented. The only way to remove conspicuous plaque is to clean it yourself.

Cleaning teeth with powder

For high-quality teeth whitening, the product under discussion must be used with a certain regularity, and to ensure that the enamel is not damaged when using a hygienic product, certain rules must be followed. The most important thing is a consultation with a dentist. Only a specialist can determine the advisability of using a particular hygiene product. If your doctor allows you to brush your teeth with powder, then you should use the product as follows:

1. Distribute a little product onto the bristles of a toothbrush: electric or mechanical - it doesn’t matter.
2. Brush your teeth, trying to treat the entire oral cavity and tongue. The more serious and thoughtful the cleaning is, the better the enamel will whiten. The procedure time should not exceed 3 minutes.
3. When all teeth have been thoroughly brushed, rinse your mouth with mouthwash. Special products are sold in pharmacies and stores.

By following simple recommendations, you will soon notice that your teeth have become much whiter. The main thing is not to overdo it, otherwise instead of a beautiful smile you may end up with problems with the enamel.

Starting line-up

Therefore, a good century-old tooth powder is one that has excellent abrasive properties. Hence they added to it: pumice, sand, ground bones, eggshells, mollusk shells, broken bricks and God knows what else. It must be said that toothpastes of those times were in no way behind powders in terms of abrasiveness. Moreover, to help a good cause, individual inventors added acids and alkalis of varying degrees of aggressiveness to them. Well, of course - after all, tartar softened by acid is easier to remove (alkali has not proven its worth in this regard). In general, the evolution of hygiene products has moved towards clearly expressed aggressiveness.

Popular brands

Harm

But in 1907, an outstanding article was published in The Dental Cosmos: Miller WD. Experiments and observations of the wasting of tooth tissue variously designated as erosion, abrasion, chemical abrasion, denudation, etc. It had about the same impact on dentists as Albert Einstein’s “On the Electrodynamics of Moving Bodies,” published two years earlier, had on physicists. Equipped with terrifying illustrations, it clearly demonstrated the monstrous abrasion of teeth (in vitro) with pastes and powders. Here's one example:

Packaging of mi&ko and Phytocosmetics tooth powders

Fitokosmetik LLC tooth powder is packaged in a box made of type 5 plastic (PP). Everything is neatly labeled. Even the lid. Everywhere there is a sign that it is acceptable to use for food purposes.

Marking on the lid of the jar from Phytocosmetics

mi&co tooth powder is sold in dark glass packaging. The cover is plastic. Inside there is a standard absorbent backing. I was hoping to find the correct marking on the bottom of the lid under the gasket to ensure a tight seal. But there's nothing there. The cover is not marked. The guys from the store @bezupakovki_sochi said that the container is returnable. But I live in another city and was hoping to recycle the packaging when I no longer need it or breaks. Now I understand that I will have to go to Sochi to return the jar to the manufacturer.

The mi&co powder cap is not marked

One can argue about which is more environmentally friendly – ​​PP or glass. I would say that in modern conditions it is more environmentally friendly if you can recycle it in your city. Here, for example, you can pass glass, but you cannot pass the “plastic five.”

Still, I think that regular tooth powder packaging is more environmentally friendly since mi&co also uses plastic, but we have no way of knowing if this cap is even recyclable.

Also, the liner cap is inconvenient for me personally because I don't like dipping my wet toothbrush into the powder. I pour the dose I need into the lid. From there I collect the powder on a brush, blurring it a little along the way. After completing the procedure, I wash the lid and place it on top of the jar, which I first cover with foil.

This is how I use powder, but add more.

Quality improvement

Of course, not all dentists read this study. Consumers of the powder certainly had no idea about it. Therefore, it took decades before highly abrasive components began to be abandoned. Such useful indicators as RDA (relative dentin abrasivity) and REA (relative enamel abrasivity) were introduced. The lower they are, the less the teeth wear out. Today, manufacturers who respect their customers indicate digital RDA values ​​on each tube. Less than 70 – low abrasiveness, 71-100 – moderate, 101-150 – high, 151-200 – very high. Here is the RDA table for some modern pastes:

Modern composition

So, coarse abrasives were disqualified from the contents of tooth powder. But what is there now? Soda, as can be seen from the table, has minimal harmful qualities. It is harmless, but its effectiveness is low. It weakly cleans plaque and does not “take away” tartar at all. Its hardness on the Mohs scale is 2.5. That's why the main ingredient in today's tooth powders is chalk (calcium carbonate). Its hardness on the Mohs scale is 3. It cleans teeth relatively gently and is more effective than soda. The rest is fragrances, flavor enhancers, dyes, etc.

What does tooth powder consist of?

The first model of the powder consisted of large chalk particles. They injured the enamel, leading to scratches and damage. New versions of the product also contain chalk, but its particles are reduced. It contains a chemically precipitated substance that prevents the thinning of the enamel.

Each product contains additional components. The performance of the tool’s functions depends on them:

• herbal extracts (relieving inflammation, destroying bacteria, reducing swelling in the eyes and other soft tissues);
• abrasive elements (increasing the strength of enamel, strengthening teeth);
• bleaches;
• sea ​​salt (whitens, enhances metabolic processes, eliminates swelling of the gums);
• clay (gently cleanses).

Note! Abrasive particles are smaller than in previous versions of the powder, so the new compositions are safe.

The final victory of toothpaste

Back in 1914, there were attempts to introduce fluoride into toothpaste. But only after large-scale research in the early 1950s, which proved the effectiveness of fluoride toothpastes, did active commercial production begin. The pioneer was Procter & Gamble with Crest toothpaste. Then the rest of the manufacturers picked up the baton. In addition to fluorides (to prevent caries), antiseptics and anti-inflammatory components (to fight gingivitis), and desensitizing substances (to reduce dental hyperesthesia) began to be added to the paste.

How to choose?

When choosing a toothpaste, pay attention to the addition to its name:

• Active – means that the product is recommended for periodontal disease,
• White – produces a whitening effect due to high abrasiveness and peroxide content (citric acid),
• Sensitive – designed to reduce excessive tooth sensitivity,
• Fito – contains medicinal herbs.

Then check: the integrity of the packaging (tube), the release date (expiration date - 3 years). Familiarize yourself with the composition of the components: fluoride concentration should not exceed 2%, abrasiveness should not exceed 100 according to the RDA standard.

Where in the world is it used?

In developed countries, tooth powder is not produced. The last known global leader in the hygiene industry, Arm & Hammer, ceased sales in 2000. In Russia, tooth powder is used by 23% of the population. A recent study was conducted in India in 2022: it was found that 31% of rural residents and 15% of urban respondents use tooth powder. A strong relationship has been found between the use of tooth powder and abrasion of tooth tissue, bleeding and gum recession. This is the “beauty” you get after consuming Indian tooth powder:

Recommendations for use

In order for the use of tooth powder to bring maximum benefits, you should follow some rules .

Storage

It is necessary, first of all, to ensure proper conditions for storing this product so that it retains its beneficial properties :

• Avoid exposure to direct sunlight;
• ensure an acceptable temperature in the room where the powder is stored: from 0 to 25°C;
• do not allow contact with water;
• ensure that the relative humidity does not exceed 70%.

General rules

The choice of a specific powder should be made using the advice of a dentist, who must take into account the individual characteristics of the patient - the condition of the soft tissues, the quality of the enamel, the presence of various problems or diseases in the oral cavity.

• Do not dip a wet brush directly into the product. You need to dilute a little product with water in a separate container and apply the resulting mixture onto a moistened brush.
• Use only a soft toothbrush to clean with powder . It can be distinguished by the “Soft” marking.
• Follow the recommendations for the duration of the procedure . The greatest cleaning effect is achieved in 3–5 minutes.
• In one procedure, you can do double brushing : first with full powder, and then with a soft and non-abrasive toothpaste.
• Use this product no more than once every three days.
• After the procedure, it is necessary to rinse the mouth very thoroughly to remove all remnants of the hygiene product, food particles and removed dental plaque.

How to brush your teeth correctly

Please note that despite the fact that most of the Indian tooth powder fan's own enamel has been erased, the black plaque has not been cleaned out everywhere. And this is on the front surface - you can imagine how much worse the situation is on the internal surfaces. This happens because brushing your teeth requires, first of all, not strength, but intelligence. Instead of violent movements, moderate but frequent movements are needed. Not horizontal, but vertical, sweeping. From the gum to the tooth: from bottom to top - on the lower jaw, from top to bottom - on the upper jaw. And, naturally, you need to brush your teeth not only on major holidays, but every day. Then the soft plaque will not yet have time to calcify and stick firmly to the enamel.

Streptococci

These include Streptococcus mutans, Streptococcus sanguis, Streptococcus mitis, etc. These are acid-forming bacteria, which are characterized by anaerobic fermentation. The main causative agent of caries is Str. Mutans. Its content in dental plaque is about 90% of the total number of microorganisms.

A direct relationship between Streptococcus mutans and enamel destruction has been proven. The more of these bacteria, the more intense the carious process develops. In addition, scientists have found that Str. mutans does not belong to the normal (natural) microflora of the oral cavity; the pathogen is transmitted from person to person through saliva.

Lactobacilli

During their life, bacteria produce lactic acid, but they themselves are resistant to it. The number of lactobacilli in dental plaque is small. However, the concentration of these microbes increases significantly with the formation of a carious cavity.

Features of use

For tooth powder, the instructions for use are a little more complicated than for toothpaste. The toothbrush should be moistened with water and the wet bristles should be dipped into a jar of powder. It is advisable to immediately collect a portion for the entire one-time cleaning. After all, when re-sampling, microorganisms will get into the powder. Bacteria, by the way, will still end up in the jar (unless you use disposable brushes), because they remain on the fibers from the previous cleaning. But in the 12 hours that have passed since the last hygiene procedure, most of the microbes have already died and do not pose any danger to the owner. The same cannot be said about other members of the family. Therefore, everyone should have a personal jar of tooth powder - otherwise there is a high risk of infecting close relatives. This is another inconvenience compared to toothpaste - the whole family can use a common tube.

  I never gave preference to tooth powders, probably because I didn’t know about their properties, and it’s not convenient to use them. Who would have thought that it could have a beneficial effect on sore gums? But despite the fact that the powder has many advantages, I will still use toothpaste. I can’t switch to powder, it doesn’t foam and is kind of cloying.

  I’ve been using tooth powders instead of toothpastes for more than two years now and I’m happy with everything. Firstly, you don’t breathe “ice” like after these thermonuclear pastes, secondly, it whitens and cleanses your teeth perfectly (I’m a coffee lover, so this is very important), thirdly, the powders are much cheaper. The only negative is the stains on the sink. There are slightly more of them than when using paste. I really like the powders and will continue to use them.

  At home I always use tooth powder. I constantly remembered the lines: “...and a fluffy towel, and tooth powder...”. One day I decided to try it, first I read about the pros and cons - I found out that before, they mostly used it, but then they stopped because it spoils the enamel. It’s just that before it contained chalk, which is an abrasive substance, but since then its composition has changed significantly. The disadvantages that remain are not significant for me.

  I once decided to try brushing my teeth with tooth powder instead of toothpaste. I didn't like it, it felt terrible. It is not easy to use, has an unpleasant taste and does not foam. And I love it when your mouth feels very fresh after brushing your teeth. There was no such sensation with the powder. I know many people prefer powder to toothpaste, but it's definitely not for me.

  On the recommendation of the dentist, I alternate the use of paste and powder. I noticed that this really gives a better result than using just one thing. It took me a while to get used to the powder. After using toothpaste, it’s a little uncomfortable that the powder doesn’t foam, but it’s all a matter of time and habit. Now I enjoy using both the powder and the paste. I visit the dentist much less often.

  I remember tooth powder from childhood, I really liked it then. But with the advent of pastes, it faded into the background and was gradually stopped being used. A couple of years ago, I accidentally came across Mint powder at a pharmacy and bought it. I alternate it with toothpaste—paste for two days, powder for a day. An excellent effect and the dentist noticed that the gums are less inflamed and there is no bleeding as before.

  I think now few people use powder to clean their teeth. This happened at least due to the fact that now there are better products, and they cost less and do not cause as much inconvenience as powder. It is very inconvenient to use the powder; over time, no one has come up with packaging that would solve a number of inconveniences. In addition, after using the powder, tooth sensitivity increases.

Reviews

Why then are there such a huge number of positive reviews about tooth powder on the Internet and among friends? It’s not surprising - there are also a lot of words of praise about homeopathy and osteopathy. Valerian, Actovegin, Linex and a hundred or two other ineffective drugs find no less devoted admirers. A person is such an amazing creature that, having convinced himself of the usefulness of a particular drug, he can actually achieve a positive effect, even if this drug is an absolute dummy. This is called the placebo effect. After persistent self-hypnosis, the transition to truly more effective therapeutic and prophylactic agents is often met with hostility. Plus, irreversible negative consequences do not occur immediately. They include, among other things, the absence of a positive impact (prevention of diseases), which few fans think about.

Composition of teeth cleaning powders

Each locality had its own recipe for tooth powder. Before people came to the idea that finely ground chalk could serve as its basis, the product was made from gypsum, corals and shells, animal horns or egg shells. And only later a chalk-based powder appeared, and various oils were used as a flavoring: anise, mint, cinnamon and clove flowers.

Later, with the development of the chemical industry, chalk began to be deposited chemically. As a result, it became even smaller. Then its composition was further enriched with magnesium carbonate, and the tooth powder stopped causing damage to the tooth coating. At the same time, it provided high-quality cleaning.

Modern tooth powder, the composition of which is much more complex than that of its ancestor, also has numerous additives that have preventive qualities. Chalk is not the main component. It can be replaced by white clay, and additional substances are, for example, volcanic tuff or sea minerals. Powders with this composition clean the teeth in a gentle manner and can act as an excellent prophylactic agent.

Natural product

In addition to the low cost and supposedly better cleansing effect, many people are attracted to tooth powder by its environmental friendliness. Sodium lauryl sulfate, methylparaben, cocamidopropyl betaine and other horrors in toothpastes cause pronounced protest and rejection among many citizens. It’s difficult to argue with anything here - if you are a staunch opponent of “chemistry”, perhaps tooth powder is your choice. Only then be consistent - if your teeth suddenly hurt, do not treat them. After all, all modern fillings, crowns, dentures, and implants are also made of artificial materials. The natural behavior would be to remove the tooth, as our ancestors did (including those who used tooth powder a hundred years ago).

Pros and cons of pasta

The paste product has the following positive aspects:

Pros:

• the presence of a large number of auxiliary components that largely eliminate inflammation, infection, plaque;
• the foam-like structure distributes the paste substance over the entire surface, ensuring cleansing in all departments;
• ease of use due to reliable sealed packaging;
• a large selection of products thanks to the medicinal component, which allows you to buy a paste for daily or course use.

Minuses:

• most products contain parabens, triclosan, sodium lauryl sulfate, which are harmful in any quantity;
• fewer abrasive particles, which does not always ensure plaque removal and stone prevention;
• quality products have great value.

Attention! The product is chosen together with the dentist. He will recommend it according to the condition of the teeth.

Reviews from doctors

Why then do dentists recommend tooth powder? Well, not all dentists, but only some. And these latter are a minority. Of this minority, one half has never read a single book on their specialty in their lives (yes, don’t doubt it – such copies exist). I read the second half, but these were reprints of Soviet textbooks from the 30s (and toothpaste was not produced in the USSR until 1950). And the third half, although familiar with modern concepts, understood little about them. If you ask such scholars the question: “What randomized controlled studies are you willing to refer to to confirm your recommendation?”, you may encounter the most unexpected response.

Popular means

As an example, here are several varieties of this product from well-known manufacturers.

Gum Gold / Gum Gold

• mint,

Conspiracy of toothpaste manufacturers

But there are also completely unique opinions from dentists. One well-known Moscow orthodontist (a competent doctor, a supporter of evidence-based medicine) posted a publication on her own website: “How dangerous is tooth powder?” With 31 links to sources of information - to give due weight to your own words. The article contains a lot of reliable information, but the conclusions are paradoxical. From the thesis about the higher abrasiveness of certain toothpastes compared to some tooth powders, the author concludes that the superiority of toothpaste over tooth powder is a myth. Formed by advertising from greedy paste manufacturers. No analysis or explanation of why evil advertisers chose for promotion a powder that was not well-known to everyone at that time, but a new, unpromoted product (and, therefore, requiring greater campaign costs) is naturally not presented. This same characteristic mistake is also popular among patients. But you only have to think a little to realize that it is much easier to advertise a cheap, low-cost, and even much more popular product to increase its selling price - and the conspiracy theory will naturally dissolve.

Which is better: toothpaste or tooth powder?

It is difficult to say unequivocally which product is best to use for whitening - each has its own characteristics. It is best to make a choice based on your own priorities:

• if you need a product that is inexpensive and can whiten crowns quickly, tooth powder will be an ideal option;
• if you need a product that whitens teeth for a relatively long time, but gently and with a longer-lasting effect, it is better to choose a special paste. You should also choose a paste with chemical active ingredients if you want to lighten your teeth to a white shade: the abrasive can whiten teeth only to their natural color, which is not white at all, but beige - due to dentin showing through the enamel (in people with thin enamel, the natural color teeth may even be light yellow). Therefore, it is possible to give teeth whiteness in the literal sense of the word only through chemical action.

Which is safer?

Tooth powder still confuses some due to the presence of small particles that can be accidentally inhaled while brushing your teeth. Indeed, there is such a possibility. But only small children should be afraid of it. Curiosity may cause them to bring the container of powder closer to their nose, and then the risk of inhaling small particles will increase. Greenway powder is not prohibited for use by children, but the manufacturer recommends doing so only under adult supervision.

Tooth powder is often accused of being unhygienic. They say that you need to dip a wet brush into it, which leads to the moistening of the granules and the proliferation of bacteria in the container with them. That's how it is. But it all depends on the composition of the product. If it contains components that kill harmful microorganisms, the risk is reduced to zero. In Greenway powder, sea salt plays the role of protection against bacteria.
