A dental abscess refers to bacterial infection that result in collection of pus that can occur in the bones or gums around the infected tooth. An abscess can start off for a number of reasons, but commonly it starts off in an infected tooth that has a cavity in it and can then spread to other areas of your mouth, as well as to your face, jaw or throat. Thus a dental abscess can become very painful when the tissue becomes inflamed.
There are two types of dental abscesses; periapical abscess and periodontal abscess. Periapical abscess are the more common of the two and refer to when the abscess forms in the bone around your tooth. Periodontal abscess on the other hand form in the supporting gums around the tooth.
Dental abscesses are usually an indication of poor dental health and result due to a lack of good and timely dental care.
If left untreated for too long, abscesses can lead to further complications and even be life-threatening, as the infection and swelling could progress to where it threatens to block the airways, which could compromise breathing. Thus it is important to visit your dentist regularly (every six months) and as soon as you face such dental difficulty.
