What is a common consequence of leaving orthodontic appliances in place too long?

Leaving orthodontic appliances in place for an extended period can lead to teeth movement. Orthodontic treatment is designed to gradually shift teeth into their desired positions through the application of controlled forces. If orthodontic appliances remain in situ beyond the intended duration, the continuous force can lead to unintended tooth movement. This may cause misalignment rather than the intended adjustments that were initially planned in the treatment.

Other consequences, while possible, are less directly tied to the prolonged use of orthodontic appliances. For example, gum infection could occur due to poor oral hygiene, which may be exacerbated by the presence of appliances, but it is not a direct consequence of leaving the appliances in place too long. Pulp necrosis is a serious condition that might arise due to trauma or extensive decay rather than the duration of appliance retention. Increased tooth sensitivity can occur from various factors, including the positioning of the appliances and the movements they induce, but it does not encapsulate the primary issue of unintended tooth movement caused by prolonged appliance use.
