If an infected tooth causes fever, fatigue, or other symptoms, the infection may be spreading to your body. You may need medical attention.

It starts with a toothache. If your sore and throbbing tooth is left untreated, it could become infected. If your tooth becomes infected and isn’t treated, the infection could spread to other places in your body.

If an infected tooth is not treated, the infection could spread elsewhere in your body, which is potentially life-threatening. Signs and symptoms that the infection in the tooth has spread include:

  • stomach pain

Call your dentist for a same-day appointment if you or your child experience any of these symptoms in addition to a toothache.
