Pressure on a tooth can eventually cause resorption provided there is a layer of connective tissue between the two surfaces. Pressure can be caused by erupting or impacted teeth, orthodontic movement, trauma from occlusion, or pathological tissue such as a cyst or neoplasm. Resorption due to orthodontic treatment is relatively common. One report of a 5 10-year follow-up after completion of orthodontic treatment found an incidence of 28.8% of affected incisors.
It may be assumed that the pressure exerted evokes a release of monocyte cells and the subsequent formation of osteoclasts. If the cause of the pressure is removed, the resorption will be arrested.
