Bruxism is consensually defined as a repetitive jaw-muscle activity, characterized by the clenching or grinding of the teeth and by the bracing or thrusting of the mandible. Considered a common parafunctional activity, its symptoms include hypersensitive teeth, aching jaw muscles, headaches, tooth wear, damage to dental restorations (e.g. crowns and fillings) and damage to teeth20. Within the several types of bruxism, sleep bruxism mostly occurs during periods of sleep arousal and tends to worsen during the day4,10.
