Why Does My Tooth Hurt When I Bite or Chew?
Pain that appears mainly when you bite or chew can provide an important clue—but it does not point to only one possible cause.
A tooth may hurt under biting pressure because of tooth decay, a crack or fracture, inflammation around the root, gum or supporting-tissue problems, or an altered bite. A recently restored tooth can also sometimes feel uncomfortable when pressure is applied.

The timing of the pain can be useful. Some people experience pain when biting down, while others notice it more when releasing the bite. Whether the pain occurs in one specific tooth or across several teeth also matters.

It can be tempting to simply chew on the opposite side and wait for the discomfort to disappear. But avoiding pressure does not necessarily resolve the underlying problem.

If biting pain persists, repeatedly returns, or is accompanied by swelling, sensitivity or spontaneous pain, the tooth should be evaluated.

Biting pain is a symptom—not a diagnosis. Finding the cause is what determines what the tooth actually needs.
