A toothache is generally the result of dental cavities (tooth decay) or sometimes
an infection. Tooth decay is often caused by poor dental hygiene, although the tendency
to get tooth decay is partly inherited.
Sometimes, pain in other locations is perceived as occurring in the teeth (this
is called referred pain or radiating pain).
Causes
- Tooth decay
- Abscessed tooth
- Earache
- Injury to the jaw or mouth
- Heart attack (can include jaw pain, neck pain, or toothache)
