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.
What Is âTooth Resorptionâ? Tooth resorption is loss of hard dental tissue, but not from decay. This means that the substance of a tooth is broken down by certain specialised body cells and then absorbed. Resorption thus causes some of a tooth, generally in the root area, to just disappear. In the developing child there is a natural physiological resorption of the roots to allow for the exfoliation, or shedding of the first set of teeth at the appropriate time.
