If your sport requires a mouth guard for players, the answer is yes. Standard mouth guards that you buy from the store and boil and bite to mold to your teeth will prevent your teeth from moving. These mouthguards will always try to force the teeth back to the position they were in when the mouth guard was fitted. Because your teeth are already on the move, you need a flat plane mouth guard that lets them continue to move while the mouthguard is worn. We are happy to provide you with an appropriate mouth guard to protect your teeth. Just ask one of the staff or the doctors when you need one.
