An abscessed is a painful infection at the root of the tooth or between the gum and the tooth. You can get an abscessed tooth due to untreated tooth decay. However you can also get an abscessed if you have trauma to your tooth, such as braking or chipping your tooth, or if you have gum disease or gingivitis. If you think you have a abscessed tooth it is very important that you see your dentist right away. The abscessed or an infection may spread from the tooth root to the bone causing a much large oral health issue.
