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 cause of these dental abscesses is direct growth of the bacteria from an existing cavity into the soft tissues and bones of the face and neck. An infected tooth that has not received appropriate dental care can cause a dental abscess to form. Poor oral hygiene (such as not brushing and flossing properly or often enough), smoking, alcohol, poor diet, and certain medical conditions and medications can increase risk of cavities to form in your teeth.
