Sports Mouth Guards
There are Three Types of Mouth Guards
Custom-fittedThese are made specifically for you by your dentist. They may be more expensive than the other versions, but because they are customized, usually offer the best fit.
StockThese are inexpensive and come pre-formed, ready to wear. However, they often don't fit well. They can be bulky and can make breathing and talking difficult.
Boil and biteThese 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.
The best mouth guard is one that has been custom made for your mouth by your dentist. However, if you can't afford a custom-fitted mouth guard, you should still wear a stock mouth guard or a boil-and-bite mouth guard from the drugstore.
