Often, it occurs during sleep; even a short nap may induce it. In a typical case, the canines and incisors are commonly moved against each other laterally, i.e. with a side to side action. This abrades tooth enamel, removing the sharp biting surfaces and flattening the edges of the teeth. Sometimes, there is a tendency to grind the molars together, which can be loud enough to wake a sleeping partner.

Over time, bruxing shortens and blunts the teeth being ground, and may lead to pain in the joint of the jaw, the temporomandibular joint, or headache. Teeth hollowed by previous decay (caries) may collapse; the pressure exerted by bruxism on the teeth is extraordinarily high.

Unfortunately, there is no accepted cure as yet; mainly as there is no accepted model of causation for the condition. Ongoing management of bruxism is based on prevention of the abrasion of tooth surfaces by the wearing of an acrylic dental guard, created to the shape of the individual's upper teeth from a bite mould. This requires trips to the dentist for measuring and fitting. Alongside this full width guard, smaller and alternative shapes can be obtained, some with proprietary names. It is worth noting that some clinicians advise against the fitting of fitted guards as a long term treatment.

If a tense jaw is experienced during wakefulness, some sufferers find it helpful to gently press their jaws open with fingertip pressure, to relax the affected muscles much as one would treat a leg cramp, but in this case, it is important to take care not to overextend the jaw joint.

Though, presently, there is no cure available for bruxers, it may be found beneficial to work at reducing stress and anxiety before bedtime, by a winding-down activity such as massage, meditation or reading, and eating early enough to ensure a fairly empty stomach at bedtime may also help. Additionally, there is some evidence to suggest that prolonged magnesium and/or calcium supplementation may alleviate bruxism.

Damaged teeth can be repaired by replacing the worn natural crown of the tooth with an artificial crown. Materials used to make crowns vary; some are less prone to breaking than others, and can last longer. Porcelain fused to metal crowns may be used in the anterior (front) of the mouth, and in the posterior (back) gold is the preferred material. To protect the new crowns, an occlusional guard may be fabricated to wear at night.
