An abscess is a collection of pus that forms in the body. It can be caused by a bacterial infection, and it can occur anywhere in the body, including the mouth. When an abscess occurs in the mouth, it is called a dental abscess. Dental abscesses are often caused by tooth decay or gum disease.
Dental abscesses can be very painful, and they can also lead to serious health problems if they are not treated. In some cases, an abscess can spread to the bloodstream, which can lead to sepsis. Sepsis is a life-threatening condition that can cause organ failure and death.
