When participating in contact sports such as football or hockey, it is important to protect all areas of your body, including your mouth. Rubber mouth guards can be purchased at all sporting goods stores and can be molded to fit your teeth. However, the initial molding may not fit properly, but don't worry, you don't need to purchase a new mouth guard because you can remold and refit the rubber guard.
Put a pot of water onto a stove top and turn the stove on high.
Wait for the stove to bring the pot to a rolling boil.
Drop the prefit mouth guard into the boiling water and leave it in for 10 to 20 seconds.
Pull the mouth guard out of the water with a pair of tongs or spoon. The hot water softens the rubber, allowing it to be reshaped.
Position the mouth guard on your top teeth and firmly bite down. Hold the bite for a few moments, and then remove the mouth guard from your mouth. The mouth guard has now been refit.
