Does bleaching teeth hurt their enamel?
No. Whitening teeth by using peroxides is commonly done. It’s true that hydrogen peroxide will damage your hair if used too often. However, the structure of hair and that of tooth enamel are very different. And if any demineralization is caused by wearing trays for bleaching, it is very quickly counteracted by your saliva. So these bleaching treatments are quite safe and your smile makeover will remain intact.
