What are the causes of an abscessed tooth?
The most common is decay. The tooth gets infected and abscesses. The other common way is through injury. Unlike other parts of the body that can swell and get lots of oxygen to the area, a tooth can not swell. The cells inside the tooth don’t get enough oxygen and thus the cells begin to complain with pain and sensitivity. If it abscesses it is called a sterile abscess.
