A toothache is one of the most common dental concerns and can range from mild discomfort to severe, persistent pain. It is often caused by tooth decay, infection, injury, or damage affecting the tooth and surrounding tissues. This can interfere with eating, sleeping, and everyday activities if left untreated. Early diagnosis and appropriate treatment help relieve discomfort, preserve your teeth, and restore lasting oral health.
Know the Signs
Common Symptoms
A toothache doesn’t always begin with severe pain, but the symptoms can gradually become more noticeable over time. If you’re experiencing any of the following signs, it’s a good idea to schedule a dental evaluation.
- Persistent Tooth Pain: Continuous aching or throbbing that doesn’t improve throughout the day.
- Hot or Cold Sensitivity: Sharp discomfort when eating or drinking hot or cold foods.
- Pain While Chewing: Pressure or discomfort when biting down or chewing everyday meals.
- Swollen or Tender Gums: Red, inflamed gums surrounding the painful or affected tooth.
- Jaw or Facial Pain: Discomfort that spreads from the tooth into nearby jaw muscles.
- Bad Taste or Odor: Infection around the tooth may cause an unpleasant taste or smell.


Why It Happens
Underlying Causes
A toothache can develop from several dental conditions affecting the teeth, gums, or nearby tissues. Identifying the underlying cause helps ensure effective treatment and long-term pain relief.
- Tooth Decay: Cavities can gradually damage the tooth, exposing sensitive inner layers to pain.
- Dental Infection: Bacteria may reach the tooth pulp, causing inflammation and ongoing discomfort.
- Cracked Tooth: Small fractures can expose sensitive nerves and trigger pain while chewing.
