A night guard or an occlusal splint is a custom made acrylic removable appliance moulded to fit your upper teeth. It is used to treat patients with bruxism, headaches, or neck pain. Bruxism, otherwise known as grinding - is excessive clenching of the teeth that is not associated with normal chewing/eating. Grinding can lead to permanent damage of your teeth or your TMJ, and wearing a splint as prescribed is often a safe and cost effective treatment option.
