what can cause an abscessed tooth in children
Tooth decay: Tooth decay is the main cause of tooth abscess for children. When tooth decay is deep down to the centre of the tooth (the pulp), bacteria can infect the pulpal tissue and the pulp becomes dead.
A tooth abscess is a pocket of pus that's caused by a bacterial infection. The abscess can occur at different regions of the tooth for different reasons. A periapical (per-e-AP-ih-kul) abscess occurs at the tip of the root, whereas a periodontal (per-e-o-DON-tul) abscess occurs in the gums next to a tooth root.
