TOOTH BEAUTY : Healthy Enamel
The secret of beautiful teeth . . . shining, translucent, naturally white . . .is healthy enamel. Not achieved via abrasion or bleaching, which may help, but can also be harmful. But by keeping the enamel itself in optimum condition. And the key to that is mineral supply.
Teeth are made of densely packed nanocrystals of hydroxyapatite, a calcium phosphate compound. In peak condition, tooth enamel is smooth, fully mineralized, and semi-transparent, revealing the ivory color of the dentin beneath, which is what gives teeth their white appearance. Though one of the hardest parts of the body, tooth enamel can easily suffer surface damage, and be dissolved by acids. In fact it requires constant care.
