CHOOSING A MOUTH PROTECTOR
There are three types of mouth protectors available, the ready made or stock mouth protector, the mouth formed protector, and the custom made protector. Although all three types provide protection, they differ in comfort, fit and cost.
No matter which type of mouthguard is chosen, however, it is preferred that only the upper teeth be covered, for the following reasons; the upper teeth usually overlap and therefore protect the lower teeth; the front teeth are the most frequently injured and; covering the lower teeth may create additional bulk, diminishing comfort and fit while providing little extra protection.
Some special circumstances, such as a protruding jaw or the presence of orthodontic appliances (braces, for example), may require that the lower teeth be covered too. Your dentist will be able to determine if such a condition might apply to you.
The most effective mouthguards combine several features. They should be resilient, light (thin enough for easy breathing), tear resistant, and comfortable. They should also be properly fitted (mouth formed and custom made protectors, for instance, are shaped to closely fit a player's own teeth). And they should be durable, easy to clean, and not difficult to speak with.
A strap is an optional item that can be fastened to almost any type of mouth protector. The strap allows the mouthguard to be removed or suspended from other face gear when the athlete is not in practice or in play. The strap also guards against loss. Its disadvantages are potential injury to the face, jaw or mouth if the strap is yanked, and added cost to the overall price of the mouthguard.
