A tooth abscess is a collection of pus that build-up inside the teeth or gums. This bacterial infection is often a result of plaque deposited on the teeth for a longer period of time. Anyone, from children to the elderly, can have an abscessed tooth.
A person with an abscessed tooth undergoes extreme pain, fever, and headache, or pain in the neck.
Tooth decay is also a major cause of dental abscesses. When left untreated, the bacteria may spread inside the soft tissue, putting the person at an increased level of developing some life-threatening conditions.
