Self-care at home

- Avoid very hot, cold, or sugary foods and drinks

Medical treatments
Dental treatments may include fillings for cavities, antibiotics for infection, root canal therapy to save an infected tooth, or extraction if the tooth cannot be saved. Your dentist will explain these options.
When is surgery considered?
Serious infections or impacted wisdom teeth may require surgery. Your dentist will refer you to an oral surgeon if needed.

- Floss daily to remove plaque between teeth

Chronic tooth pain can cause stress, anxiety, or trouble sleeping. It is important to address the pain with a dentist to improve your overall well-being.
Prevention
Most tooth pain can be prevented with good oral hygiene and regular dental visits. Eating a healthy diet and avoiding tobacco also help.
Complications
If left untreated
- Spread of infection to other teeth or to the jaw
- Abscess that can spread to the neck, face, or bloodstream (sepsis)

Long-term outlook
With proper treatment, most tooth pain can be resolved. Early care leads to the best outcomes and helps save your natural teeth.
