Why a filling may be needed
A hole in a tooth usually starts as decay. Bacteria in plaque turn the sugar in food and drink into acid, and over time the acid breaks down the hard outer layer of the tooth, called enamel. A white spot can be an early sign, and early decay can have no symptoms at all.
Children's teeth have softer and thinner enamel and decay more easily than adult teeth, which is worth knowing if you are reading about Kids dentistry. Regular Check-up and clean visits give your dentist the chance to find decay early, when treatment can stop it or even cure it.
