Why Is My Tooth Throbbing? 7 Possible Causes and When to See a Dentist

A throbbing tooth can be difficult to ignore. The pain may come and go, become worse at night, or seem to pulse along with your heartbeat.

But what does a throbbing tooth actually mean?

Tooth pain is your body’s way of telling you that something may need attention. While not every toothache is a dental emergency, persistent or severe throbbing pain should not be ignored.

What Can Cause a Throbbing Tooth?

Several dental conditions can cause throbbing or pulsating pain.

1. Tooth Decay

A cavity begins when bacteria and acids damage the outer surface of a tooth. Early decay may cause few or no symptoms.

As decay progresses deeper into the tooth, however, you may begin experiencing sensitivity or pain.

2. Dental Infection or Abscess

An infection involving the inside of a tooth or the surrounding tissues can cause significant pain.

Possible symptoms can include:

• Persistent or throbbing tooth pain
• Swelling
• Tender gums
• Pain when chewing
• Sensitivity to hot or cold
• A bad taste in the mouth
• Fever or feeling unwell

Dental infections require professional evaluation and should not be ignored.

3. Cracked or Damaged Tooth

A crack isn’t always visible.

Some patients experience pain primarily when biting or releasing pressure after biting. Others develop sensitivity to temperature.

Even if the tooth looks normal, a dentist may need to evaluate it.

4. Gum Disease

Pain that feels as though it is coming from a tooth can sometimes originate in the tissues surrounding it.

Inflammation or infection involving the gums may cause tenderness, swelling, bleeding, or discomfort around the teeth.

5. Previous Dental Work

Temporary sensitivity can sometimes occur following certain dental procedures.

However, pain that is severe, worsening, persistent, or accompanied by other symptoms should be evaluated.

6. Teeth Grinding or Clenching

Grinding or clenching your teeth can place significant pressure on the teeth and jaw.

Some people do this while sleeping and don’t realize it.

Possible signs include morning jaw soreness, headaches, worn teeth, or generalized dental discomfort.

7. Wisdom Teeth

Partially erupted or impacted wisdom teeth can sometimes contribute to pain, inflammation, or infection around the back of the mouth.

My Tooth Stopped Hurting. Does That Mean It’s Better?

Not necessarily.

Pain can change for many reasons. A reduction in pain does not always mean the underlying dental problem has resolved.

This is especially important when significant pain suddenly disappears after being present for some time.

A dentist can determine what is happening beneath the surface.

When Is Tooth Pain an Emergency?

Seek prompt professional evaluation when tooth pain is severe or accompanied by concerning symptoms such as significant facial swelling, fever, difficulty swallowing, or difficulty breathing.

Difficulty breathing or swallowing associated with facial or oral swelling can require emergency medical attention.

What Should I Do About a Throbbing Tooth?

The most important step is determining why the tooth hurts.

Pain medication may temporarily reduce discomfort, but it does not diagnose or correct the underlying dental problem.

Depending on the cause, treatment could range from relatively simple restorative care to treatment for infection or other dental conditions.

Early evaluation can often provide more treatment options.

Don’t Ignore Persistent Tooth Pain

Your tooth doesn’t have to hurt constantly for a problem to exist.

If you are experiencing persistent, recurring, or severe tooth pain, schedule a dental evaluation.

Finding the cause early can help protect your oral health and prevent a manageable dental problem from becoming more complicated.
