What Is an NTI Appliance?
Relief for Headaches and Clenching, Available in Cambridge
An NTI appliance is a small custom oral device designed to help reduce the effects of clenching and grinding by limiting excessive muscle activity during sleep or periods of tension. It is often used as part of a TMJ/TMD treatment plan to help relieve pressure on the jaw joints and surrounding muscles. At Sweet Spot Dental, NTI appliances may be recommended for patients experiencing symptoms related to muscle strain, jaw discomfort, or nighttime clenching.
