Mouthguard use has been shown to reduce the risk of sports-related dental injuries.

Types of Mouth Guards
ANSI/ADA Standard No. 99:2001 defines three categories of mouthguards, typically made up of thermoplastic ethylene-vinyl acetate (EVA). They vary in cost, adaptability, comfort, level of contact with teeth, and safety efficacy.

Stock (ready-made)
These are the most commonly available and least expensive type of mouthguard. They are available at drug stores and sporting goods stores and do not require dentist visits. Because they are available in a limited range of sizes, they are not fitted to the user’s mouth, and the mouth must be kept shut to keep it in place. Research suggests they are the least effective type of mouthguard.

Mouth-formed (boil and bite)
These self-adapting mouthguards are designed to soften when placed in hot water, then cooled and placed into the mouth. The product is then adapted to the user’s mouth by bite pressure and manipulation by the tongue and fingers. A dental professional may assist with the final molding, particularly if the user has orthodontic appliances. Boil and bite mouth guards are available at sporting goods stores and are designed for home use.

Custom Made
Custom mouthguards are fabricated in a dental office or laboratory from individual patient impressions. They provide the best fit, adaptability, and efficacy but are the most expensive and require dental visits.
