Nutrition
Acidic foods and beverages are consumed more frequently today. These changes in eating and drinking habits attack tooth enamel and thus contribute to its erosion.
Hydroxyapatite is the main component of our tooth enamel. It protects the teeth from irritants and damage. Over time, however, this tooth mineral wears away.
With the hydroxyapatite in Bioniq dental care products, daily use can help support dental health.
Definition : What is hydroxyapatite?
Hydroxyapatite is a mineral from the calcium phosphate group and is characterized by its very high degree of hardness. It is a component of our bones and teeth. While bones consist of about 60% hydroxyapatite, the hydroxyapatite content in our teeth is significantly higher.
In the tooth, the inner dentin is composed of around 70% of this mineral. The outer part, the enamel, consists of about 97% hydroxyapatite, which makes it the hardest substance in our body. Hydroxyapatite is responsible for the strength and stability of our body and our teeth.
However, the hydroxyapatite contained in tooth enamel, in particular, naturally wears down over time and cannot be reproduced by the body.

The outermost layer of the tooth, the enamel, consists of 97% hydroxyapatite. It protects the underlying layers. Our body cannot regenerate worn-down enamel on its own.
Based on the principles of bionics, scientists have succeeded in recreating artificial tooth enamel that is very similar to natural human enamel.
Scientifically Tested Formula
The key ingredient hydroxyapatite has been studied in more than 300 studies. The scientific findings clearly show:
Hydroxyapatite supports healthy teeth and gums!
Whiter Teeth
Hydroxyapatite deposits on the tooth surface and makes the teeth appear brighter. New discolorations have difficulty adhering to the smooth tooth surface.
Bionics : Hydroxyapatite from Bionics
The term "bionics" describes the combination of biology and technology. It involves applying a natural phenomenon to a technical system. This idea has already been successfully implemented in many everyday objects:
The camera lens was modeled after the human eye
The water- and dirt-repellent lotus effect
Helicopters are inspired by the flight of dragonflies
These are just a few of the many examples from bionics. Nature is a popular model because we know it works. Some of these systems have stood the test of time over millennia and have prevailed through evolution. Our dental care products containing hydroxyapatite are another successful example!
Protective Function : Why is tooth enamel important?
Tooth enamel has to withstand a lot: eating, drinking, chewing, and other external influences such as teeth grinding put it under daily strain.
The high resistance of enamel protects the underlying layers of the tooth from wear. However, due to continuous stress, enamel itself is gradually worn down. Calcium and phosphate in saliva can at least partially protect and remineralize the enamel.
If enamel is damaged, it becomes rough and porous. Bacteria can adhere more easily, increasing the risk of dental diseases that can ultimately lead to tooth loss. At the same time, wear makes the teeth appear more yellow. In addition, enamel protects the tooth from demineralization caused by acids that are formed as breakdown products of sugar after eating.
Wear and Tear : How does tooth enamel wear away?
Tooth enamel is subject on the one hand to natural wear and gradually wears down, for example through chewing food. However, this is a very slow process. On the other hand, there are additional factors that promote enamel loss and can therefore contribute to premature wear:
Toothbrushing Technique
Brushing too hard or using a toothbrush with stiff bristles can damage tooth enamel and contribute to its wear over time.
Plaque
Plaque is a film of bacteria and food debris that forms on the teeth. If it is not removed regularly, acids are produced that attack and demineralize the enamel: Tooth decay and periodontitis can develop if plaque is not removed regularly.
Teeth Grinding
Teeth grinding, which usually occurs at night and unconsciously, subjects the tooth enamel to intense pressure and friction, causing the tooth structure to gradually wear away.
