Why a night guard may help
Night guards help protect teeth from bruxism, or grinding and clenching. Sleep problems, stress and dental factors may contribute to grinding, so it is worth discussing the cause with your dentist. Repeated grinding can chip or crack teeth, strain jaw muscles and put pressure on the jaw joints.
How a custom guard is made
A dental professional takes an impression of your mouth, and a laboratory makes the guard to fit your teeth. Custom guards can provide a better fit and may be more comfortable than an over-the-counter device, though they generally cost more. Your dentist will recommend the material and design for your needs.
How it works
The guard fits over your teeth and keeps opposing tooth surfaces from grinding directly against each other. Its main job is to protect your teeth; it can also help reduce the effects of clenching and grinding. Ask your dentist to check the fit and discuss any continuing jaw discomfort.
Whether this fits you depends on an exam. Bring your questions to any visit, and see insurance and payment for cost questions.
