Night guards, also known as bruxism guards, are custom-made oral appliances designed to protect teeth from damage caused by grinding or clenching during sleep. Bruxism can lead to tooth wear, fractures, jaw pain, headaches, and temporomandibular joint (TMJ) disorders if left untreated. Before prescribing a night guard, the dentist evaluates tooth wear patterns, jaw alignment, and symptoms such as muscle tension or jaw discomfort. Digital scans or impressions are taken to ensure a precise fit that is comfortable and effective. The night guard is fabricated from durable materials and designed to absorb and redistribute pressure created by grinding forces. Patients receive instructions on proper use, cleaning, and storage to maintain hygiene and appliance longevity. Regular use of a night guard helps prevent long-term dental damage, reduces jaw strain, and protects existing restorations, making it an important preventive treatment for patients with bruxism.
