A tooth abscess is an infection of the tooth that is usually caused by untreated tooth decay or gum disease, or a serious tooth injury that affects the pulp, such as fracture. The result is a pus-filled, often painful infection that requires immediate medical treatment to prevent tooth loss and the spread of infection into surrounding teeth and even the bones of the face or sinuses.

If you find yourself having to wait a day or two to be seen by your dentist, there are some at-home treatments you can do while you wait to alleviate the discomfort caused by the abscess.
