Why can cracked teeth be difficult to diagnose?

There is no single test that finds every crack. The tooth may look normal on an x-ray, the bite test may be negative, and symptoms can be intermittent. The crack may also be hidden beneath an old filling.

How Do We Diagnose a Cracked Tooth?

Diagnosis usually comes from these methods:

  • Combining the history with magnification — Using magnification, your dentist can pinpoint small cracks and fractures in your tooth. 
  • Cold testing — A cold test can indicate an infection inside your tooth if you experience lingering sensitivity. 
  • Bite testing — This test shows how your bite comes together, which can indicate a cracked tooth.
  • Transillumination — A test where a focused beam of light is shown through a tooth to spot micro-cracks, which show up as shadows.
  • X-rays X-rays can give a picture of what is happening internally with a tooth.
  • Examination after an old restoration is removed — We may find bacteria and decay lodged beneath an old restoration like a crown or filling, causing damage or an infection. 

Your Brisbane dentist may combine multiple diagnostic procedures to determine the severity of your cracked tooth.
