If it's only a small abscess, the dentist may perform a root canal to totally remove the infection and preserve the tooth.

This is accomplished by cutting a tiny slit in the gums and allowing the pus to drain. After that, the affected area is cleansed with saline.

Antibiotics work rather quickly to treat tooth infections and alleviate discomfort. If you follow your healthcare provider's advice, amoxicillin should take effect within a few days. However, even if the pain and swelling are gone, you have to finish your course of antibiotics as prescribed.

While you wait for the amoxicillin to take effect, your dentist may advise you to use painkillers such as ibuprofen to alleviate the symptoms. If a tooth is infected, a dentist may also tell patients that saltwater mouthwash can help.

If somehow the antibiotic medicine doesn't work, a dentist may suggest a root canal, tooth extraction, or removal of the affected tissue. Should you not feel better after a week or your symptoms are getting worse, get medical help from a medical professional.
