Enamel damage from debonding metal brackets is relatively rare. The purpose of this case report is to demonstrate that the risk of enamel or dental crown fracture is present when removing metal orthodontic brackets. It is advisable to take appropriate preventive measures, including examination of the anterior teeth for enamel cracks, prior to treatment. Patients should be fully informed of the risks of orthodontic treatment. Without pretreatment diagnosis and documentation, it is difficult for the orthodontist to prove that the appearance of enamel cracks or enamel/tooth fracture is unrelated to orthodontics.
