Pain that shows up specifically when you bite or chew is a pretty distinct symptom and it usually points to a handful of common causes. Here's what might be going on, and how to know when it's time to see a dentist.

Common Causes of Pain When Biting Down

1. Tooth Decay (Cavities)

A cavity that has grown large enough can cause pain when pressure is applied, especially it it's close to the nerve.

2. A Cracked Tooth

Crackes aren't always visible to the eye, but they can cause sharp, sudden pain when you bite down, especially if the crack extends toward the tooth's nerve. This is sometimes called "cracked tooth syndrome."

3. A Loost or Failing Filling/Crown

Older dental work can shift, crack, or come loose over time, creating pain when pressure is applied unevenly.

4. Tooth Grinding (Bruxism)

Grinding or clenching, especially at night, puts excess pressure on teeth and can cause soreness that's noticeable when chewing.

5. Infection or Abscess

An infection at the root of a tooth can cause pain that worsens with pressure, sometimes accompanied by swelling or a bad taste in the mouth.

6. Sinus Pressure

Occasionally, upper back teeth ache when biting due to sinus pressure or congestion, not a dental issue at all. This is usually accompanied by other cold or allergy symptoms.

7. Gum Recession or Exposed Roots

When gums recede, tooth roots become more sensitive, and biting pressure can cause discomfort in exposed areas.

How to Tell If It's Serious

Seek dental care soon if:

• Pain is sharp, sudden, or severe
• It's only on one specific tooth (rather than general soreness)
• You notice swelling, a bad taste, or fever
• The pain persists for more than a day or two
• You can see a visible crack or damage

What to Do in the Meantime

• Avoid chewing on the affected side
• Take over-the-counter pain relief if needed
• Avoid very hot, cold, or hard foods
• Rinse gently with warm salt water

Getting to the Root of the Problem

Pain when biting down is your tooth's way of telling you something isn't right and pinpointing the exact cause usually requires an exam and possibly an X-ray, since some issues (like small cracks or infections) aren't visible to the naked eye.
