   Fluoride Free Toothpaste. The main ingredient in this option is nano-hydroxyapatite, which helps re-mineralize teeth. Plus, this toothpaste also contains essential oils.

3. Hydroxyapatite - Wikipedia

   en.wikipedia.org/wiki/Hydroxyapatite

   Hydroxyapatite is widely used within dentistry and oral and maxillofacial surgery, due to its chemical similarity to hard tissue. [34] In the future, there are possibilities for using nano-hydroxyapatite for tissue engineering and repair. The main and most advantageous feature of nano-hydroxyapatite is its biocompatibility. [35]

4. Topical fluoride - Wikipedia

   en.wikipedia.org/wiki/Topical_fluoride

   Fluoride has a high tendency to react with the calcium hydroxyapatite Ca10(PO4)6(OH)2 in tooth enamel due to its high affinity to metals. [8] [10] It subsequently replaces the hydroxide group in hydroxyapatite to precipitate calcium fluorapatite Ca5(PO4)3)F. [8] These fluorapatite precipitations scavenge excess phosphate and calcium in the saliva to form a supersaturated solution for ...

5. Remineralisation of teeth - Wikipedia

   en.wikipedia.org/wiki/Remineralisation_of_teeth

   When fluoride ions are present in plaque fluid along with dissolved hydroxyapatite, and the pH is higher than 4.5, [16] a fluorapatite-like remineralised veneer is formed over the remaining surface of the enamel; this veneer is much more acid-resistant than the original hydroxyapatite, and is formed more quickly than ordinary remineralised ...

   In 1980, the Japanese company, Sangi Co., Ltd., launched APADENT, the world's first remineralizing toothpaste to use a nano-form of hydroxyapatite, the main component of tooth enamel, rather than fluoride, to remineralize areas of mineral loss below the surface of tooth enamel (incipient caries lesions).

7. Dentin hypersensitivity - Wikipedia

   For this reason, the number of toothpastes and mouthwashes that already incorporate nano-hydroxyapatite as a desensitizing agent is increasing. [14] Bioglass is a relatively new technology in toothpaste formulations. BioMin, a bioactive glass of calcium fluoro phosphosilicate, provides faster and longer lasting relief against sensitivity ...
