A dental or tooth abscess is a buildup of pus that forms inside the teeth or gums, this is often a result of deep decay, caries or gum infections.
The source of gum infections are determined if it arises from the tooth or gums itself. Clinical examinations of the abscessed site is done and x-rays are needed to know more about its nature and severity.
Root canal treatment can be performed to treat the tooth, depending on the quality of the remaining tooth structure it may result in the extraction of the tooth. If the abscess is originating from the gums they may need deeper cleaning and follow-ups to monitor healing.
