What is bruxism?

Bruxism is the technical term for involuntary teeth grinding or clenching, which most often occurs during sleep but can also occur during the day. It is a repetitive and unintentional movement of the jaw that can lead to tooth wear, muscle and joint pain, or sleep disorders.

Causes of bruxism

Bruxism can be caused by various factors.

The most common causes are stress and psychological tension. Other causes include sleep disorders (e.g., sleep apnea), an unbalanced bite or orthodontic abnormalities, excessive consumption of caffeine or alcohol, and neurological or psychological factors.
The cause is often a combination of several factors, which is why individual assessment is important.

Symptoms and complications

Teeth grinding may not be immediately noticeable, but over time it can cause:

  • Visible tooth wear, cracks, or chips
  • Tooth sensitivity to temperature and pressure
  • Jaw muscle, head, or ear pain, especially in the morning
  • Stiffness or pain in the jaw joint
  • Sleep disturbances and fatigue

For some patients, the first sign may be a warning from their dentist.

Treatment options for bruxism

The treatment of bruxism depends on its cause and severity.

Most commonly includes:

Custom-made night guards (splints) that protect teeth from further damage.

Furthermore, physiotherapy and relaxation exercises help relieve muscle tension. Other options include psychological or relaxation therapy, orthodontic or prosthetic solutions for malocclusion or missing teeth, or pharmacological support as recommended by a doctor.
Early diagnosis and a comprehensive approach significantly increase the success rate of treatment.
