The purpose of a mouthguard is to protect your teeth during sporting activities, including contact and non-contact sports, that may result in a collision causing fractured, cracked or impacted teeth and tongues. A custom-fitted mouthguard is made by taking impressions of your upper teeth and works to prevent dental trauma by absorbing and spreading the impact of a collision.  It is critical that your mouthguard is designed to fit the exact contours of your mouth to ensure it stays in place, your breathing is not restricted, and you are able to talk normally. Only your Dentist can design and manufacture a custom-fit mouthguard to effectively protect your teeth, lips and tongue during sport.
