If you are a skater who has ever been involved in any other contact sport, you have probably worn a mouth guard. Mouth guards, mouthpieces, sports guards and mouth protectors are different names for that small device worn over teeth to protect them from face or head impacts. These guards come basic or customized - in a variety of colors and even flavors. What's important is that if the guards fit properly, they will prevent or reduce injury to a skater's teeth as well as the cheeks, tongue, lips and gums.
Mouth Guard Construction
Most people know that these guards protect teeth, but few have any idea that what they are made of might make a difference in the level of protection they can provide. Mouth guards are commonly made of thermoplastic - a polymer that can be shaped when heated. This moldable plastic is resistant to cracking and splitting under stress, so it is a good choice for this type of protective gear. Some mouth guards also are made of polyurethane which has elasticity, flexibility and durability. Polyurethane feels like rubber. Basic mouth guards are made of plastic, which used to be the material of choice.
How Does a Mouth Guard Work?
A mouth guard is a shock absorber that cushions your mouth from the effects of head, face, or neck impacts and protects teeth from fractures. Your mouth guard can also prevent lacerations on the tongue, lips, and cheeks by keeping them away from your teeth.
A mouth guard works best if it is comfortable, does not affect breathing, is durable and is easy to clean. It's nice if you can talk with it in your mouth, too. Most mouth guards are designed to cover the upper teeth only. There may be special cases when your dentist will make a mouth guard for the lower teeth as well - for skaters with braces or other dental gear. The best plan is to let the dentist recommend the right mouth guard for you.
