When a crack cuts through more than the enamel, then treatment is needed to prevent problems like an infection or a deeper fracture. Depending on how severe a crack is, your dentist may recommend a crown, a root canal, or removal of the tooth. In some cases filling material can be used to repair the crack and a crown can stop it from getting worse. If the soft tissue inside your tooth has been affected, then your doctor may recommend a root canal to remove damaged tissue. According to dentists, while a root canal is a more intense treatment than a crown, it can help to save your tooth in the case of a fracture that has affected the whole tooth. A final option is to have the molar removed. This is done when the tooth cannot be saved because the root of the tooth has been damaged.
Accidents, very hard foods, and even teeth grinding can lead to cracks or fractures. See your dentist right away to find out what can be done for your tooth.
