The most researched toothbrush tablet in the world

Scientific studies and tests

Scientifically developed and tested in laboratory studies, clinical studies, field studies.

Fluoride availability in the tablet

Laboratory tests showed that the fluoride is distributed significantly better in the mouth than with toothpaste due to the special formulation as a tablet.

About the study


Laboratory studies have shown that fluoride toothbrush tablets have a high remineralization potential. The fluoride in the tablet dissolves quickly in saliva and can repair the affected areas on the teeth.

About the study

Removal of coatings

A clinical study found significant plaque reduction after 14 to 21 days with Denttabs toothbrush tablets.

About the study


A clinical study showed that Denttabs toothbrush tablets, with their low abrasion value, remove plaque as well or better than toothpaste with a high abrasion value.

Fluoride in dental care

Why do we need fluoride for teeth?

Simply put: Fluoride forms a kind of protective film around your teeth and protects them from caries. To better grasp fluoride, it helps to understand how tooth decay occurs in the first place:

Our teeth are made up of enamel, dentin and dental cementum. Enamel is the hardest substance in the human body and consists mainly of calcium and phosphate. Our teeth are surrounded by a biofilm (plaque) that contains numerous microorganisms. These bacteria break down carbohydrates from food into acids. The acids can damage the tooth because they dissolve calcium and phosphate from the enamel, thus softening it. Fluoride counteracts this. It improves the remineralization of the teeth by helping to reincorporate the minerals into the tooth lattice. It also builds up the enamel and makes it more resistant to acids. The enamel thus regains an intact surface.

What is the fluoride content in the tablets?

We offer two different fluoride contents in Denttabs: The fluoride content in the Mint tablets is 1450 ppm (parts per million). The Strawberry tablets have a fluoride content of 500 ppm, which has been adapted for children. Both values are guideline values that are recommended and internationally recognized.

How does the fluoride in the toothbrush tablets work?

The fluoride in the tablet is proven to dissolve very quickly and only in saliva and can thus repair the affected areas on the teeth.


What does remineralization mean?

Remineralization means "rebuilding of minerals." Our teeth are surrounded by a biofilm (plaque) that contains numerous microorganisms. Many species of bacteria metabolize short-chain carbohydrates from food into acids. The acids harm the tooth because they dissolve calcium and phosphate from the enamel, softening it.
Remineralization can stop or even repair tooth decay in the early stages. This is where our saliva plays a very important role: it consists of water, proteins and minerals, such as calcium and phosphate. Demineralized teeth, i.e. damaged teeth, can insert these minerals like small building blocks into decalcified (demineralized) areas and thus maintain the protective enamel. Fluoride accelerates this process. Denttabs toothbrush tablets with fluoride have an optimal remineralization potential, as the fluoride in the tablet has been proven to dissolve very quickly and only in saliva, repairing the affected areas on the teeth. Denttabs allow the tooth to rebuild and recover.

Removal of deposits and abrasiveness

How does Denttabs clean my teeth?

Denttabs works with a unique principle: the polishing effect. This works with the cellulose, which can polish your teeth ultra-smooth to the interdental spaces. Therefore, new particles can simply roll off the tooth surfaces. Coatings, also known as plaque, can practically never form on polished surfaces. A clinical study confirmed that Denttabs achieved significant plaque reduction after 14 to 21 days.

What does abrasiveness mean?

Abrasiveness expresses how much a dental care product wears down or abrades the tooth. It is made measurable by the RDA value (RDA = Radioactive Dentin Abrasion), which is taken as a guide value for the cleaning effect. Abrasive dental care products aim to remove plaque without attacking the enamel. When buying your dental care product, make sure that it does not contain any abrasive substances or surfactants that are too aggressive.

What is the abrasion value of Denttabs?

The abrasion value, also called RDA value, is 21 for Denttabs, which stands for very low abrasiveness. Silica and small amounts of the gentle surfactant sodium lauroyl glutamate ensure the low abrasiveness and equally desirable reduced foaming.

However, this does not mean lower cleansing efficacy. In a clinically controlled study, three differently abrasive toothpastes were compared: A whitening toothpaste with an RDA of 162, a tooth gel with an RDA of 0, and Denttabs with an RDA of 35 (at that time, a value of 35 was estimated; in 2021, an RDA of 21 was calculated for Denttabs by the consumer organization Consumentenbond from the Netherlands). The cleaning performance achieved across all measured tooth surfaces averaged just over 50% for all three toothpastes (toothpaste: 50.9%, Denttabs: 54.4%, tooth gel: 51.6%). Denttabs thus achieved the best cleaning performance. A common perception is that plaque can be cleaned away with a high level of abrasiveness. The study proved the opposite.
