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 effects of trauma on primary teeth vary and include pathologic changes such as pulp necrosis, internal and/or external root resorption, ankylosis, and obliteration of the pulp canal. One of the most frequently observed sequela is pulp necrosis, which often necessitates tooth extraction.
