Hydroxyapatite is a key element in tooth structure.
Enamel hydroxyapatite nHAp™ creates a bright white appearance and prevents diffused light reflection by closing small pores from the enamel surface.
Tooth enamel contains 96% hydroxyapatite and 4% organic matter and water. Dentin contains 65% hydroxyapatite.
nHAp™ replaces tooth enamel and dentin apatite, so it is incorporated into toothpastes to restore the surface of demineralized enamel and dentin by depositing hydroxyapatite nanoparticles in defects.
