Mouth guards protect the gums and teeth from injury. They are oftentimes used in sports to prevent injury or tooth loss. Guards can also be used to alleviate snoring and are a solution to bruxism.
Bruxism is the grinding of your teeth while you sleep. This involuntary action can damage your teeth, do harm to your jaw, and result in headaches. Night guards are custom-fitted to the mouth to protect your teeth from having contact with each other during the night.
