Cracked Tooth

Tooth cracks are a common occurrence in dentistry. Diagnosing cracks and treatment planning for tooth longevity are critical factors for helping patients maintain their teeth.There are five types of tooth cracks. These types are:

  • Craze lines
  • Fractured cusp
  • Cracked tooth
  • Split root
  • Vertical root fracture

Understanding and identifying these five types can provide guidance for treating cracked teeth. The numerical order of these cracks, from top to bottom, signifies the general prognosis for a particular crack. That is, craze lines have a good prognosis, whereas a vertical root fracture has a very poor prognosis. Regardless of the current diagnosis, cracks in teeth do not repair themselves and small cracks often progress into bigger, more threatening conditions.
