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 main causes of dental abscesses are tooth decay and trauma. With regular tooth decay, small cavities can lead to big problems if they go untreated. Once the bacteria reach the root of the tooth, the infection can take hold quickly. Age can play a factor in tooth decay as well.
