Why Does My Tooth Hurt? 7 Common Causes of Tooth PainTooth pain can range from a brief sensitivity to an intense, throbbing ache. Because many different dental problems can cause similar symptoms, determining the source of a toothache generally requires a professional examination.

Here are seven common reasons your tooth may hurt.

1. Tooth Decay

A cavity begins when acids produced by plaque bacteria contribute to loss of minerals from the tooth structure. Early decay may cause no symptoms.

As decay advances into deeper layers, sensitivity or pain may develop.

2. A Cracked or Damaged Tooth

Cracks can cause pain when biting or chewing, sensitivity to temperature, or intermittent discomfort.

Some cracks are difficult to see without a dental examination.

3. An Infected Tooth

If bacteria reach the dental pulp—the soft tissue containing nerves and blood vessels inside the tooth—significant inflammation or infection can develop.

Symptoms may include persistent pain, sensitivity, swelling, or tenderness.

4. Gum Disease

Not every toothache originates inside a tooth. Inflamed or infected periodontal tissues can cause tenderness and discomfort around teeth.

5. Tooth Sensitivity

Exposed dentin from gum recession, enamel wear, cavities, or other conditions can make teeth sensitive to cold, heat, sweets, or touch.

6. Teeth Grinding or Clenching

Bruxism can place substantial stress on teeth and jaw muscles. Some patients experience morning tooth tenderness, jaw soreness, headaches, or worn teeth.

7. A Problem With a Filling or Restoration

Fillings, crowns, and other restorations can wear, fracture, loosen, or develop problems at their margins over time.

New discomfort around a previously treated tooth deserves evaluation.

When Is Tooth Pain an Emergency?

Seek prompt dental attention for severe pain, facial swelling, trauma, uncontrolled bleeding, or signs of spreading infection. Difficulty breathing or swallowing associated with facial or oral swelling warrants emergency medical attention.

Frequently Asked Questions About Toothaches

Can a toothache go away on its own?

Pain can temporarily improve even when the underlying problem remains. Persistent or recurring tooth pain should be evaluated.

Does severe tooth pain always mean I need a root canal?

No. Treatment depends on the diagnosis. Tooth sensitivity, decay, fractures, periodontal problems, and bite issues can produce pain for different reasons.

Why does my tooth hurt when I bite?

Possible causes include a crack, inflammation around the tooth, decay, a restoration problem, or other conditions.

Why does cold water make my tooth hurt?

Cold sensitivity may occur with exposed dentin, decay, a cracked tooth, pulp inflammation, or other dental conditions.

Should I see a dentist for mild tooth pain?

If discomfort persists, recurs, or is associated with other symptoms, schedule an examination rather than waiting for it to become severe.
