A tooth fracture is a break or crack in the hard shell of the tooth. The outer shell of the tooth is called the enamel. It protects the softer inner pulp of the tooth that contains nerves and blood vessels. Depending on the type of fracture, the tooth may not cause any problems or it may cause pain.

Types of tooth fractures include:

  • Craze lines—shallow cracks that cause no pain and require no treatment
  • Fractured cusp—breaks in the chewing surface of the tooth
  • Cracked tooth—the tooth cracks from the chewing surface down toward the root of the tooth
  • Split tooth—cracks down through the root, separating a section of tooth
  • Vertical root fracture—cracks begin in the root and move up toward chewing surface
