A majority of patients clench/grind their teeth at night time when they are sleeping. This is known as bruxism and it can be very traumatic. Not only for your teeth, but also for your jaw muscles and TMJ. Patients who suffer from bruxism have great benefits from wearing nightguards. Nightguards act to reposition your jaw and prevent stress on the muscles and joints. This helps to protect the teeth and is imperative in preventing future problems. The stress from clenching/grinding can lead to tooth wear, fractured teeth, gum recession and TMJ disease.
