An abscess is a collection of pus that forms in the body. It can be caused by a bacterial infection, a foreign object, or a blocked duct. Abscesses can occur anywhere in the body, but they are most common in the skin, lungs, and abdomen.
Dental abscesses are a type of abscess that occurs in the mouth. They are usually caused by a bacterial infection of the tooth pulp, the soft tissue inside the tooth. Dental abscesses can be very painful and can lead to serious complications, such as sepsis and osteomyelitis.
