Toothache: Symptoms, treatment and prevention

Toothache is a common reason for visiting the dentist. Pain from toothache can affect the teeth and jaws. Tooth decay is a common reason for toothache, which won't usually get better on its own.

Toothache pain can be constantly throbbing, or may be set off by food or drink.

Causes of toothache

As well as tooth decay, toothache may be caused by:

Symptoms of toothache

Symptoms of toothache 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

When should I see a dentist about a toothache?

See your dentist as soon as possible if:

  • You have a toothache that lasts longer than one or two 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 their spread to other parts of the face and skull and possibly even to the bloodstream.

What happens when I go to the dentist with a toothache?

To treat your toothache, your dentist will first obtain a brief medical history and conduct a physical examination. He or she will ask questions about the pain, such as when it started, how severe it is, where it is located, what makes it worse, and what makes it better. Your dentist will examine your mouth, teeth, gums, jaws, tongue, throat and neck. X-rays may be taken as well as other tests, depending on what your dentist suspects is causing the toothache.

What treatments are available for toothache?

Treatment for a toothache depends on the cause. 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 done if the cause of the toothache is found 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. Phototherapy with a cold laser may also be used to reduce the pain and inflammation associated with the toothache.

How can toothaches be prevented?

Since most toothaches are the result of tooth decay, following good oral hygiene practices can prevent them. Good oral hygiene consists of brushing regularly with a fluoride-containing toothpaste, flossing once a day, and seeing your dentist as often as advised for check-ups and dental cleaning. In addition to these practices, eat foods low in sugar and ask your dentist about sealants and fluoride applications.
