The lifespan of a night guard depends on the severity of your teeth grinding and the specific material of the guard. Typically, night guards can last anywhere from six months to a few years. However, we recommend regular check-ups with your dentist to ensure your guard is still in good condition and serving its purpose effectively. At Smile Time Dental, your dental health is our top priority. Don’t hesitate to reach out to us with any further questions or to schedule an appointment today!
