Toothache is pain in or around a tooth.
Pain - tooth or teeth
A toothache is often the result of dental cavities (tooth decay) or an infection. Tooth decay is often caused by poor dental hygiene. The tendency to get tooth decay is also partly inherited.
Sometimes, pain that's felt in the tooth is actually due to pain in other parts of the body. This is called referred pain. For example, an earache may sometimes cause tooth pain.
You can use over-the-counter pain medications while waiting to see the dentist or primary health care provider.
The dentist may recommend antibiotic therapy and other treatments, like a root canal for toothaches caused by a tooth abscess.
Use good oral hygiene to prevent tooth decay. 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.
