With proper care, your teeth can last a lifetime. Only very slight tooth wear as we age is normal – anything more is considered dental disease, same as cavities or gum disease. By “wear,” we mean loss of tooth structure. Wear starts with loss of the hard, translucent enamel, which is actually the human body’s hardest substance. Enamel is highly resistant to wear and chemical attack, as it would have to be given what your teeth do every day: bite, chew, and come in contact with acidic foods and drinks.
Still, it is possible for tooth enamel to wear down for various reasons. Your body has ways of compensating for minor wear. But when tooth wear becomes more significant, intervention will be necessary to keep your bite functioning properly and protect your teeth.
