Many of us grind and clench our teeth at night. This grinding and clenching can lead to chronic headaches, jaw pain and muscle tightness first thing in the morning. Over time this can also cause significant damage to your teeth. If you have these symptoms, or if Dr. Olson notices excessive wear-and-tear during your exam, she might recommend a custom night guard to protect your teeth while you sleep. In addition to saving you a great deal of discomfort, a night guard can also save you time and money on future dental treatment.
