Strawberry blonde woman with glasses with her hand over her mouth - perhaps needing root canal from an affordable dentist

Do cracks in teeth show up on x-rays?

Last month, I was a passenger in a car that was involved in an acceded. The airbag did not go off. My entire face hit the dashboard very hard. My teeth were hurting, but I couldn’t see any damage. My dentist x-rayed my teeth and didn’t see any damage. She referred me to an endodontist who also did an x-ray. The endodontist said I need a root canal for two teeth that are cracked. I am wondering if I need to get a third opinion and another x-ray. Should a crack in a tooth show up in an x-ray? I cannot afford root canal treatment. – Jennifer from TN

Jennifer- A crack in a tooth will show up only if the x-ray is taken at the correct angle—the exact angle of the crack. So, it is difficult to see on an x-ray that a tooth is cracked.

Although a general dentist may not detect a crack, endodontists are more skilled at reading x-rays. Even if the endodontist could not detect a crack on the x-ray, he likely saw evidence in your tooth that it is cracked.

You may seek another opinion, but it is unlikely that another x-ray will reveal the problem with your teeth.

If you cannot afford root canal treatment, ask the endodontist how long you have before you risk losing your tooth. A crack can progress, lead to infection, and result in tooth loss if it is not treated.

You may have time to save money for treatment. Another possibility to ask the endodontist about financing or payment plans. Low- or no-interest financing is available through CareCredit and other companies to help you pay for dental treatment.
