When an athlete takes a blow to the face, it could result in a cracked or fractured tooth.
If a tooth shows longitudinal cracks or cracks that appear across the tooth, it might only have what dental professionals call "craze lines." These are superficial cracks in the enamel and aren't high risk for dental health.
However, if a tooth's crack or split begins at the tooth's crown and extends downward, it's a bona fide cracked tooth.
With a cracked tooth, you might experience such symptoms as:
- Sharp pain when you bite down.
- Tooth pain that comes and goes but isn't always present.
- Pain while eating and drinking, especially when you consume hot or cold foods.
- The loss of a section of the tooth's outer enamel shell can expose the subsequent layers of your tooth.
The layers below the enamel are a hard layer called the dentin followed by soft tissue known as the pulp (the location of your tooth's nerves and blood vessels), according to the American Association of Endodontics (AAE).
Because a cracked tooth isn't always visible to the naked eye, you might have one and not experience any pain. Only during your next dental checkup will the damage be discovered. (Another reason regular dentist visits are essential.)
If the crack is a vertical fracture that doesn't extend beyond the visible part of your tooth, it usually won't cause you to lose a section of your tooth and expose the tooth pulp.
But, if the crack extends beyond the gumline, it could affect the cusp, the tooth's pointed tips. This might be a cuspal fracture, requiring a tooth extraction or a root canal to avoid bacterial infection.
