A night guard is a removable, custom-fitted appliance that fits on your upper teeth. Night guards are made from a hard acrylic material that is formulated to help protect your teeth from damage caused by clenching and grinding. Initial impressions are taken and sent to a dental lab where the night guard is fabricated. Once received back in the office the night guard is delivered to you and any adjustments that need to be made are done so. A night guard is a great way not only to prevent damage that can be costly to repair, but also protect the investment you have already made in your smile.
