- Tooth decay
- Abscessed tooth
- Tooth fracture
- A damaged filling
- Repetitive motions, such as chewing gum or grinding teeth
- Infected gums
Symptoms may include:
- Tooth pain that may be sharp, throbbing, or constant. In some people, pain results only when pressure is applied to the tooth.
- Swelling around the tooth
- Fever or headache
- Foul-tasting drainage from the infected tooth
See your dentist as soon as possible if:
- You have a toothache that lasts longer than 1 or 2 days
- Your toothache is severe
- You have a fever, earache, or pain upon opening your mouth wide
Proper identification and treatment of dental infections is important to prevent its spread to other parts of the face and skull and possibly even to the bloodstream.
Your dentist will obtain your medical history and conduct a physical exam. He or she will ask you questions about the pain, such as when the pain started, how severe it is, where the pain is located, what makes the pain worse, and what makes it better. Your dentist will examine your mouth, teeth, gums, jaws, tongue, throat, sinuses, ears, nose, and neck. X-rays may be taken as well as other tests, depending on what your dentist suspects as the cause of your toothache.
Treatment depends on the cause of your toothache. If a cavity is causing the toothache, your dentist will fill the cavity or possibly extract the tooth, if necessary. A root canal might need to be performed if the cause of the toothache is determined to be an infection of the tooth's nerve. Bacteria that have worked their way into the inner aspects of the tooth cause such an infection. An antibiotic may be prescribed if there is fever or swelling of the jaw.
Since most toothaches are the result of tooth decay, following good oral hygiene practices can prevent toothaches. Good oral hygiene practices consist of brushing regularly with a fluoride-containing toothpaste, flossing once daily, and seeing your dentist twice a year for professional cleaning. In addition to these practices, eat foods low in sugar and ask your dentist about sealants and fluoride applications.

Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
Muscle SpasmsMuscle spasms are involuntary muscle contractions that come on suddenly and are usually quite painful. Dehydration, doing strenuous exercise in a hot environment, prolonged muscle use, and certain diseases of the nervous system may cause muscle spasms. Symptoms and signs of a muscle spasm include an acute onset of pain and a possible bulge seen or felt beneath the skin where the muscle is located. Gently stretching the muscle usually resolves a muscle spasm.
Problems With Dental FillingsExperiencing tooth sensitivity and pain are common problems after having a dental filling. People with allergies to metal may suffer allergic reactions to amalgam (silver) fillings. Fillings may chip, crack, or wear away from the continual pressure of chewing, clenching, and grinding.
Root CanalA root canal is a dental procedure that's used to save an infected tooth. Treatment involves removing the tooth's nerve and pulp and then cleaning and sealing the tooth. Symptoms and signs that indicate a root canal is needed include toothache, discoloration, swelling, tenderness, prolonged sensitivity to hot or cold, and a persistent pimple on the gums. Typically, a root canal is no more painful than having a filling placed.
