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.
Over time, all areas of an affected tooth, from root to crown, may become involved. Tooth resorption is a common condition, affecting an estimated 20 percent to 60 percent of all cats and close to three-quarters of those five years of age and older.
