What causes tooth root resorption? A: A study on external root resorption in the journal Schweiz Monatsschr Zahnmed states that trauma, periodontitis, orthodontic treatment, internal bleaching, cysts, tumors or stimuli from a necrotic dental pulp may cause tooth root resorption.
An abscessed tooth is a painful infection at the root of a tooth or between the gum and a tooth. It's most commonly caused by severe tooth decay. Other causes of tooth abscess are trauma to the tooth, such as when it is broken or chipped, and gingivitis or gum disease. These problems can cause openings in the tooth enamel, which allows bacteria to infect the center of the tooth (called the pulp).
