An abscess in the tooth refers to an infection that was caused by a pocket of pus residing in the tissue around the tooth. Abscesses are very serious conditions, and can lead to serious matters if they aren’t treated immediately. When the pulp of a tooth dies due to damage or decay, bacteria will begin to grow from the dead tissue that is left. This bacteria will eventually spread from the root of the dead tooth into the tissue that is below and create a pocket of pus – the abscess.
