Symptoms of a 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 such as while chewing or eating.
• 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 about your toothache 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.

• If a cavity is causing the toothache, your dentist will fill the cavity or possibly extract the tooth, if necessary.
• A root canal might be needed 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.

How Can Toothaches Be Prevented?

• Brush regularly with a fluoride-containing toothpaste.
• Floss once daily.
• Rinse once or twice a day with an antiseptic mouthwash.
• Visit your dentist twice a year for professional cleaning.

• Ask your dentist about sealants and fluoride applications.
