Athletic Mouth Guard Mouthguards, also called mouth protectors, help cushion a blow to the face, minimizing the risk of broken teeth and injuries to your lips, tongue, face or jaw. They typically cover the upper teeth and are a great way to protect the soft tissues of your tongue, lips and cheek lining. When Should You Wear a Mouthguard? When it comes to protecting your mouth, a mouthguard is an essential piece of athletic gear that should be part of your standard equipment from an early age. Types of Mouthguards The best mouthguard is one that has been custom made for your mouth by your dentist. Custom Made These are made by your dentist for you personally. They are more expensive than the other versions because they are individually created for fit and comfort. Boil and Bite These mouth protectors can be bought at many sporting goods stores and drugstores and may offer a better fit than stock mouth protectors. They are first softened in water (boiled), then inserted and allowed to adapt to the shape of your mouth. Stock These are inexpensive and come pre-formed, ready to wear. Unfortunately, they often don’t fit very well. They can be bulky and can make breathing and talking difficult.
