Sleep-related bruxism, also commonly known as teeth grinding during sleep, is a term used to describe a rhythmic movement disorder characterized by the excessive grinding, clenching, or gnashing of the teeth while a person is asleep. This involuntary act typically occurs during various sleep stages, particularly during non-rapid eye movement (NREM) sleep, and it often goes unnoticed by the individual experiencing it.
Sleep-related bruxism is considered a parasomnia, falling under the category of sleep disorders. It is believed to affect a significant portion of the population, with prevalence rates varying among different studies. Individuals of all ages, from children to adults, can experience bruxism during sleep, but it is more common in children.
The exact causes of sleep-related bruxism are not fully understood, although a combination of factors such as genetics, psycho-social factors, stress, anxiety, and sleep disordered breathing may contribute to its development. This condition can lead to a range of symptoms, including worn or damaged teeth, jaw pain or soreness, headaches, and temporomandibular joint (TMJ) disorders.
Treatments for sleep-related bruxism focus on managing the symptoms and reducing the potential complications associated with teeth grinding. An oral appliance, such as a dental splint or mouthguard, may be prescribed to protect the teeth and alleviate pressure on the jaw joints. Additionally, stress management techniques, relaxation exercises, and addressing any underlying factors contributing to the bruxism may be recommended.
Overall, sleep-related bruxism is a sleep disorder characterized by the involuntary grinding or clenching of teeth during sleep, requiring appropriate management to protect oral health and improve overall sleep quality.
