Excessive gum-chewing is non-physiologic. The soft, small mass stimulates the proprioceptive fibers in the periodontium to distort the pattern of neuromuscular reciprocal innervation. These excessive, afferent stimuli cause forcible, sustained contractions of the masticatory muscles that are beyond their physiologic capacity to resolve. And in tense, emotional persons, the constantly repeated contractions often result in partial tetanies of those muscles.
