A healthy bite or occlusion involves harmony of the teeth and temporomandibular joint (TMJ). If teeth are not properly aligned or if teeth are missing, then the existing teeth may be overloaded and become loose. In addition, excess forces from clenching or grinding on inflamed tissues weakens the periodontal ligament and bone. To help restore a stable bite, reshaping the biting surfaces of the teeth, referral for orthodontic evaluation, and/or fabrication of a meticulously adjusted acrylic night guard will help reduce trauma. At times, your general dentist may also have to replace worn restorations and reconstruct damaged teeth prior to fabrication of the night guard.
