Researchers have recently perfected hydroxyapatite, a material for mineralising bones and teeth.

They did so by adding a complex of amino acids to hydroxyapatite and were able to form a dental coating that replicates the composition and microstructure of natural enamel. The improved composition of the material repeats the features of the surface of the tooth at the molecular and structural level, and in terms of strength surpasses the natural tissue.

The new method of dental restoration can be used to reduce the sensitivity of teeth in case of abrasion of enamel or to restore it after erosion or improper diet.
