A tooth that hurts when you bite down is giving you information that shouldn't be ignored. Sometimes the cause is minor and easy to correct. In other cases, pain with biting can be a sign of a cracked tooth, decay, an irritated nerve, or excessive pressure from grinding or clenching.
Understanding the pattern of the pain can help your dentist determine where to look and what type of treatment may be necessary.
Pain during biting usually means that pressure is affecting a tooth, its supporting tissues, or the surrounding structures.
The discomfort may happen when you bite down, when you release your bite, or only when chewing certain foods. These differences can provide useful clues about the underlying problem.
One common cause of pain when biting is a cracked tooth. A small crack may not be visible, particularly when it develops beneath an existing filling or in the back of the mouth.
You may notice:
Cracks can become larger when the tooth continues to experience pressure. Having the tooth evaluated early can help determine whether it can be protected before the damage becomes more extensive.
A cavity doesn't always cause constant toothache. If decay reaches deeper into the tooth, biting pressure may produce discomfort.
Sensitivity to sweets, cold drinks, or hot foods may accompany the pain. A dentist can determine whether decay is responsible and whether the tooth needs a filling or another type of restoration.
When a tooth has lost significant structure, restorative dentistry can help rebuild and protect it.
Dental fillings can wear down over time. A filling may develop a crack, become worn, or allow decay to form around its edges.
Pain when chewing on a tooth with an older restoration is a good reason to have the filling examined. Replacing a failing restoration may prevent additional damage to the natural tooth.
Teeth are designed to handle normal chewing forces, but repeated clenching and grinding can place considerably more pressure on them.
Over time, this can contribute to:
When tooth pain occurs alongside jaw discomfort or signs of grinding, an evaluation through TMJ/TMD dentistry can help determine whether excessive bite forces are contributing to the problem.
Inflamed gums and the tissues surrounding a tooth can sometimes become sensitive to pressure. Gum disease may also affect the structures supporting the teeth when it becomes more advanced.
Bleeding, swelling, recession, persistent bad breath, or tenderness around the gumline are reasons to have your gum health evaluated. Regular preventative dentistry visits can help detect these problems before they become more serious.
Pay attention to exactly when the discomfort occurs.
Pain when biting down: This can occur with a cracked tooth, decay, a high restoration, or inflammation around the tooth.
Pain when releasing the bite: This pattern can sometimes occur with a cracked tooth.
Pain that lingers after cold or heat: Lingering sensitivity may indicate irritation deeper inside the tooth.
Constant or worsening pain: Persistent discomfort deserves prompt evaluation, particularly if swelling or other symptoms develop.
These patterns don't provide a diagnosis by themselves, but they give your dentist useful information during an examination.
If biting hurts, avoid repeatedly testing the tooth. Constantly biting down to see whether it still hurts can place additional stress on an already irritated area.
Instead:
Do not place aspirin directly on the tooth or gum, as this can irritate the tissue.
Schedule an evaluation if biting pain continues, returns repeatedly, or is accompanied by sensitivity, swelling, a cracked filling, or a visible change in the tooth.
More urgent dental attention is appropriate when significant swelling, fever, or difficulty swallowing or breathing develops.
The sooner the cause is identified, the more straightforward treatment may be. If you're experiencing pain when chewing or biting, use the Contact Us page to request an appointment with Dr. Rodney Baier and the Sandy Springs dental team.
