Consistently greater masticatory forces stimulate adaptive remodeling of the periodontal ligament (PDL). This mechanical loading results in an increased width of the periodontal ligament to better absorb and distribute occlusal forces, protecting the tooth and surrounding bone. The PDL adapts by enhancing collagen turnover and vascularity, which maintains periodontal health under higher functional demands. This response is crucial in preventing excessive tooth mobility and maintaining proper tooth support.
