You bite into an apple at lunch or brush your teeth before going to bed, when suddenly your tooth starts hurting. You’ve never experienced this feeling before, but it’s certainly uncomfortable and you think you need to do something about it. If the feeling persists, it’s best to see your dentist to check for a cavity.
A cavity is caused by plaque that dissolves your tooth enamel. If left untreated, a cavity can get worse and damage the inner part of the tooth or the root. Cavities can cause tooth loss, infection or chewing problems as well.
If your dentist determines you have a cavity, the next step will be to fill it. They are commonly made of glass particles, synthetic resin and a setting ingredient.
