What is the main consequence of applying heavy forces on teeth?

Applying heavy forces on teeth during orthodontic treatment can lead to significant biological responses that may include potential tissue damage or resorption. When excessive force is exerted on the periodontal ligament, the pressure can exceed the tissue's tolerance, disrupting its healthy functioning. This can result in a detrimental reaction such as the resorption of the tooth root or surrounding alveolar bone, which compromises the integrity of the supporting structures.

The body's response to this heavy force can hinder the desired orthodontic movement, ultimately leading to complications that may require additional treatment to correct. Therefore, managing the amount of force applied is critical in orthodontic practice to avoid these adverse effects and ensure that tooth movement is both safe and effective. This understanding emphasizes the importance of using appropriate force systems that promote gradual tooth movement while preserving the health of the supporting periodontal tissues.
