Could Mouth Guards Boost Sports Performance?

Stock Mouthguard: The stock mouthguard, available at most sporting good stores, come in limited sizes (usually small, medium, and large) and are the least expensive and least protective. The prices range approximately from, $3 to $25. These protectors are ready to be used without any further preparation; simply remove from the package and immediately place in the mouth. They are bulky and lack any retention, and therefore must be held in place by constantly biting down. This interferes with speech and breathing, making the stock mouthguard the least acceptable and least protective. This type of mouthguard is often altered and cut by the athlete in an attempt to make it more comfortable, further reducing the protective properties of the mouthguard. It has been suggested and advised in the medical/dental literature that these types of mouthguards not be worn due to their lack of retention and protective properties.

As sports dentists and health professionals interested in injury prevention, we do not recommend this type of mouthguard to our patients and athletic teams. See photo of Stock Mouthguard after use for several weeks.

Mouth formed or Boil and Bite Mouthguard: Presently, this is the most commonly used mouthguard on the market. Most marketing and advertising in the past has been for this type mouthguard. Made from thermoplastic material, they are immersed in boiling water and formed in the mouth by using finger, tongue, and biting pressure. Available in limited sizes, these mouthguards often lack proper extensions and repeatedly do not cover all the posterior teeth. Dental mouth arch length studies have shown that most boil and bite mouthguards do not cover all posterior teeth in a majority of high school and collegiate athletes. Athletes also cut and alter these bulky and ill fitting boil and bite mouthguards due to their poor fit, poor retention, and gagging effects. This in turn further reduces the protective properties of these mouthguards. When the athlete cuts the posterior borders or bites through the mouthguard during forming, the athlete increases their chance of injury, especially concussion, from a blow to the chin. Some of these injuries, such as concussion, can cause life long effects
