An abscessed tooth has a pocket of pus in an area near the root of the tooth which is usually from an infection. An abscess can occur in different regions of the tooth for different reasons. A tooth abscess can be very painful and if you don’t seek tretment, it may lead to infection that spreads throughout the body.
Cellulitis affects the skin and soft tissues beneath the skin. A tooth abscess can be the cause of facial cellulitis. This serious condition can cause swelling and when that happens, the infection can spread rapidly throughout the body.
Pericoronitis refers to inflammation and infection of the gum tissue around the wisdom teeth. Wisdom teeth refer to the third and final set of molars, which appear during adolescence or early adulthood.
Wisdom teeth that have yet to erupt or have only partially emerged are likely to cause pericoronitis. It is possible for partially-erupted wisdom teeth to leave behind a flap of gum tissue. This flap collects particles from food and other things that enter your mouth, making it a prime area for bacteria growth.
