What is a cracked tooth and why does it happen?
A cracked tooth is simply a tooth that has developed a crack somewhere on the tooth structure. A cracked tooth differs from a fractured tooth because there is not missing tooth structure that might make it very obvious that there is an issue. While our teeth all have natural grooves that are considered the normal anatomy of a tooth, these cracks form independently of grooves, and are very often on areas of a tooth that do not have such anatomy. Cracks on teeth can be caused by a myriad of reasons. More than one factor can be at play at the same time for a patient. Conditions that cause a cracked tooth include: teeth grinding (bruxism); large fillings that weaken the integrity of the tooth around it; habitual behaviors such as nail biting or ice chewing; accidents or sports injuries; age related degradation of tooth structure.
