Night Guard

A dental night guard is a protective device worn over the teeth during sleep to prevent damage caused by teeth grinding (bruxism) or clenching. It serves as a barrier between the upper and lower teeth, reducing the risk of wear, fractures, and other dental issues associated with these habits.

When a Dental Night Guard is Needed

1. Bruxism (Teeth Grinding): Individuals who grind their teeth during sleep need a night guard to protect their teeth from excessive wear and damage.
2. Teeth Clenching: Those who clench their jaws tightly during sleep can benefit from a night guard to alleviate pressure on the teeth and jaw muscles.
3. Temporomandibular Joint Disorders (TMD/TMJ): A night guard can help manage symptoms of TMD/TMJ by reducing strain on the jaw joint and muscles.
4. Dental Restoration Protection: Patients with dental restorations like crowns, bridges, or veneers may use a night guard to protect these investments from damage caused by grinding or clenching.
5. Jaw Pain or Headaches: Night guards can help alleviate jaw pain, headaches, and other discomforts related to bruxism or clenching.
