What is cracked tooth?
A cracked tooth is simply what it sounds like, a crack in the tooth. Teeth are made up of three layers, the hard outer layer the enamel, an inner layer the dentin, and the nerve of the tooth lies below the dentin. Cracks typically start in the outer layer of the tooth and can progress into the underlying layers if no treatment is rendered. Early detection is key because as cracks progress in the tooth, they can lead to an infection and loss of the tooth.
