What are two potential complications of orthodontic tooth movement?

Root resorption and loss of anchorage are two potential complications associated with orthodontic tooth movement that can significantly affect treatment outcomes. Root resorption occurs when the body’s pressure response during tooth movement results in the breakdown of root structure, which can lead to shortened roots and potential tooth mobility in severe cases. This can adversely impact the stability and longevity of the teeth involved in orthodontic treatment.

Loss of anchorage refers to the failure of the supporting structures to maintain the desired position of teeth during movement. Effective anchorage is crucial in orthodontics, as it ensures that forces applied to the teeth move them in the intended direction without undesired movement occurring elsewhere. If anchorage is lost, the treatment can become less effective, and additional complexities may arise, necessitating changes in treatment plans.

The other options, while they represent possible oral health issues, are not typically classified as direct complications of orthodontic tooth movement itself or are less specific to the mechanical aspects of orthodontics as clearly as root resorption and loss of anchorage.
