Teeth are constantly exposed to mechanical and chemical attacks, as many drinks and foods, even healthy fruits, contain acids. As a result, the protective enamel surface becomes rough and porous. Microscopic defects occur, which can lead to sensitive teeth, as stimuli reach the tooth nerve through exposed dentinal tubules. Exposed tooth necks can also cause sensitivity. Biorepair addresses the cause of sensitive teeth with artificial enamel: zinc carbonate hydroxyapatite (microrepair). These Biorepair crystals seal the exposed dentinal tubules and bond with the surface of the enamel. Through a biomimetic action principle, Biorepair naturally repairs the enamel surface with twice-daily application. It prevents sensitivity. Biorepair sensitive cleans particularly gently with mild cleaning agents. The teeth feel smoother immediately, and it helps prevent cavities and gum problems.
