Teeth grinding (bruxism) and jaw joint disorders (TMJ disorders) are typically caused by stress, dental misalignment, or structural problems in the jaw joint. Teeth grinding usually occurs unconsciously during sleep and involves clenching or grinding of the teeth, leading to tooth wear, sensitivity, jaw pain, and headaches.

Jaw joint disorders are characterized by symptoms such as pain during jaw movements, clicking or popping sounds, and jaw locking. Treatment for these conditions often includes the use of night guards (dental splints), intraoral therapies, hot-cold compresses, stress management techniques, physical therapy, and muscle relaxants.

In more advanced cases, surgical intervention or orthodontic treatment may be required. Early diagnosis and intervention can reduce the impact of these conditions and help prevent more serious complications in the long term.
