The tooth consists largely of hydroxyapatite (tooth enamel approx. 97% and dentine approx. 70%). Therefore, the use of this very hydroxyapatite as a biomimetic component of dental care preparations is only logical. This review summarizes the numerous advantages and indications of hydroxyapatite.

​

Numerous studies prove the effectiveness of hydroxyapatite on sensitive teeth and exposed tooth necks. This particulate component is able to accumulate on the tooth and close exposed dentinal tubules. This closure means that external stimuli (cold, heat, etc.) cannot penetrate to the tooth nerve.

​

But also erosion, caries and periodontitis can be effectively prevented with hydroxyapatite as the main component of toothpastes and mouthwashes. By using hydroxyapatite it could be shown that the biofilm that triggers caries and periodontitis on tooth surfaces is reduced to the same extent as can be achieved with CHX. In contrast to CHX, hydroxyapatite is the biomimetic alternative. Clinical studies have shown that hydroxyapatite is a versatile ingredient in home dental care.
