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.
The bacteria can also infect the tissue within the pulp, causing a dental abscess. Tooth decay typically occurs in the teeth at the back of your mouth, known as the molars and premolars. These are large flat teeth that you use to chew food.
