2. Tooth enamel - Wikipedia

   en.wikipedia.org/wiki/Tooth_enamel

   The enamel on primary teeth has a more opaque crystalline form and thus appears whiter than on permanent teeth. The large amount of mineral in enamel accounts not only for its strength but also for its brittleness. [6] Tooth enamel ranks 5 on Mohs hardness scale (between steel and titanium) and has a Young's modulus of 83 GPa. [4] Dentin, less ...

   P11-4 is a self-assembling β-peptide. It builds a 3-D bio-matrix with binding sites for Calcium-ions serving as nucleation point for hydroxyapatite (tooth mineral) formation. The high affinity to tooth mineral is based on matching distances of Ca-ion binding sites on P11-4 and Ca spacing in the crystal lattice of hydroxyapatite.

4. Hydroxyapatite - Wikipedia

   en.wikipedia.org/wiki/Hydroxyapatite

   Hydroxyapatite is the main mineral component of enamel in teeth. [22] During demineralisation, calcium and phosphorus ions are drawn out from the hydroxyapatite. The mineral ions introduced during remineralisation restore the structure of the hydroxyapatite crystals. [22]

   Saliva helps replace these minerals, but it can’t keep up with our carbohydrate-rich diets. Fluoride excels at re-mineralizing tooth enamel. “Just a very tiny bit of fluoride in the water has ...

   Enamel's primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. [12] The large amount of minerals in enamel accounts not only for its strength but also for its brittleness. [10] Dentin, which is less mineralized and less brittle, compensates for enamel and is necessary as a support. [12]
