What complication can arise from improper use of headgear?

Improper use of headgear can lead to root resorption, which is a serious complication. Headgear is designed to apply specific forces to the teeth and jaws to influence their position and growth. However, if the traction is not applied correctly—whether through inappropriate fitting, excessive force, or inadequate patient compliance—it can lead to unintended consequences like root resorption.

Root resorption occurs when the body breaks down and absorbs the tissue that makes up the root of the tooth. This can happen due to excessive or misdirected forces that are inadvertently applied to the teeth through the headgear. Signs of root resorption can include mobility of the teeth and changes in radiographic appearance, which can ultimately compromise the stability and health of the affected teeth.

The potential for root resorption highlights the importance of careful treatment planning and monitoring when using appliances like headgear. Understanding the forces being applied and ensuring they are within safe limits is essential in orthodontic treatment to minimize the risk of such complications.
