Toothache is pain in or around a tooth.

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).

• Tooth decay
• Abscessed tooth
• Earache
• Injury to the jaw or mouth
• Heart attack (can include jaw pain, neck pain, or toothache)
• Sinusitis

Over-the-counter pain medications may be used while waiting to see the dentist or primary health care provider.

For toothaches caused by a tooth abscess, the dentist may recommend antibiotic therapy and other treatments, like root canal.

To prevent tooth decay, use good oral hygiene. A low sugar diet is recommended along with regular flossing, brushing with fluoride toothpaste, and regular professional cleaning. Sealants and fluoride applications by the dentist are important for preventing tooth decay.
