The optimal orthodontic force is one that moves teeth rapidly without resulting in structural damage, while causing the least amount of discomfort or pain. Factors that need to be considered for any orthodontic appliance are the '''magnitude''' of the force, the '''distribution''' of the force and the '''duration''' of the force. The ideal force is a '''light continuous force'''. Heavy continuous forces are damaging and should be avoided. Apart from the orthodontic forces applied, normal growth processes and forces from the [[Lips|lips]], [[Cheeks|cheeks]] and [[Tongue - Anatomy & Physiology|tongue]] resting on the teeth will determine the outcome of the treatment. | The optimal orthodontic force is one that moves teeth rapidly without resulting in structural damage, while causing the least amount of discomfort or pain.
