What is a dental abscess?
A dental abscess is an infection of the head or neck that begins as a tooth infection. Dental abscesses are often painful and filled with pus. The infection can originate as a result of poor dental hygiene, injury to the mouth, or medical conditions that affect the immune system.

A dental abscess begins when bacteria invade a tooth through an area of decay in the tooth (known as dental caries) or through the gums. The bacteria can cause an infection in and around the tooth, and this infection may then spread to other parts of the mouth and, more rarely, into the face or neck.
A dental abscess can be a serious condition because the infection, particularly when left untreated, may spread and cause serious complications. Spread of the infection by local extension or through the bloodstream can lead to serious infections of the jawbone, brain, heart valves, or lungs. Therefore, a dental abscess should be immediately treated by a physician or dentist. Dental abscesses are typically treated by opening the infection, cleaning the area thoroughly to remove any bacteria, and administering antibiotics.
Even if your dental abscess does not cause such serious symptoms, it should still be evaluated by a dentist or physician. Seek prompt medical care if you have a pus-filled lesion inside the mouth, or pain or tenderness in the mouth, throat or face associated with a toothache.
