A night guard is a custom-fitted, clear, soft or hard aligner that is worn to protect the teeth from clenching or grinding during sleep. Bruxism (teeth grinding) can be caused by a number of factors, including stress or anxiety and misaligned teeth. Symptoms of bruxism may include jaw soreness, dull headaches, painful or loose teeth, and tooth fractures.
Teeth withstand an incredible amount of force during normal chewing and functioning. Habits such as grinding or clenching during sleep put additional forces on the teeth that can result in tooth wear or fracture. A mouth guard is a great way to help protect your natural teeth as well as any restorative dental work that you have had.
A night mouth guard can also be used when performing strenuous exercise such as weight lifting.
