How do I know if my teeth are cracked?

Cracked teeth show a variety of symptoms, including erratic pain when chewing, possibly with the release of biting pressure, or pain when your tooth is exposed to temperature extremes. In many cases, the pain may come and go, and your dentist may have difficulty locating which tooth is causing the discomfort.

Can a hairline crack in a tooth heal itself?

It is possible for a tooth to repair itself if the damage is minimal. For example, if a tooth with a crack on the outer level and a minimal fracture line that does not cause pain may repair itself over time. The healing process is known as remineralization and refers to the minerals in our mouths.
