There are three types of mouth guards:
Stock mouth protectors are preformed and come ready to wear. They are inexpensive and can be bought at most sporting good stores and department stores. However, little can be done to adjust their fit, they are bulky and make breathing and talking difficult and they provide little or no protection. Dentists do not recommend their use.
Boil and bite mouth protectors also can be bought at many sporting goods stores and may offer a better fit than stock mouth protectors. The "boil and bite" mouth guard is made from thermoplastic material. It is placed in hot water to soften, then placed in the mouth and shaped around the teeth using finger and tongue pressure.
Custom-fitted mouth protectors are individually designed and made in a dental office or a professional laboratory based on your dentist's instructions. First, your dentist will make an impression of your teeth and a mouth guard is then molded over the model using a special material. Due to the use of the special material and because of the extra time and work involved, this custom-made mouth guard is more expensive than the other types, but it provides the most comfort and best fit and protection.
Generally, mouth guards cover your upper teeth only, but in some instances (such as if you wear braces or another fixed dental appliance on your lower jaw), your dentist will make a mouth guard for the lower teeth as well. Your dentist can suggest the best mouth guard for you. An effective mouth guard should be comfortable, resist tears, be durable and easy to clean, and should not restrict your breathing or speech.
