Tooth growth and development involve complex biochemical and physiological processes. Some vitamins are required as coenzymes, but these molecules are also needed to synthesize specific proteins with structural or transport functions. Collagen synthesis is carried out by ascorbic acid interaction. Vitamin A induces calbindin synthesis. Collagen and calbindins are both involved in the mineralization and development of hard tissues. The formation, eruption and growth of teeth are also mediated by the interaction of several hormones.
