What is bruxism? Bruxism is defined by repetitive jaw-muscle activity characterized by grinding or clenching of the teeth and/or by bracing or thrusting of the mandible. It can occur during sleep or during wakefulness.
Bruxism in healthy individuals may be a risk factor for negative oral health consequences such as: severe tooth enamel wear, fractured/damaged teeth, tooth sensitivity headaches and jaw muscle soreness.
Sleep bruxism is prevalent in 1-5% of the adult population and 3-49% in the children and adolescent population, according to a study as recent as 2019. It has been significantly associated with stress and anxiety. Other factors associated with bruxism include use of alcohol, caffeine, tobacco, some psychotropic medications.
Researchers have also found a correlation between sleep apnea and bruxism. In sleep apnea when the airway becomes constricted the muscles of the jaw activate by protruding the mandible and restoring the airway.
