Abstract: An improved mouthguard is provided for use by individuals having orthodontic appliances, such as braces. The mouthguard comprises an outer guard portion and an inner subguard portion. The subguard provides a barrier between the outer guard and the user's braces, thereby allowing the outer guard to be custom fit to the user's mouth and teeth using methods known in the art. Additionally, the subguard is secured to the outer guard, producing a one-piece mouthguard, and allows the mouthguard to be removably secured to the user's braces, increasing the comfort and retention of the mouthguard within the user's mouth. The mouthguard effectively protects the users braces, as well as the user's teeth and mouth, from potential damage arising out impacts suffered by the user during sporting activities while improving the user's comfort and performance in sports by allowing the user to breathe and speak uninhibited during the sporting activity.

Abstract: A miniaturized mouthpiece for repositioning the user's mandible, thereby creating an edge to edge relationship of the user's anterior teeth, without covering or extending to the user's posterior teeth. This miniaturized mouthpiece may be formed from a substantially trapezoidal mouthpiece blank having major and minor sides that are substantially parallel to one another. These major and minor sides may be connected by two equal length non-parallel sides. This blank will typically have a gently curved and raised contact area that follows the curvature of the user's anterior dental arches. The mouthpiece blank will often be made of a thermoplastic material, so that upon application of heat, the blank can be deformed around the user's maxillary central incisors and often the user's maxillary lateral incisors as well, thus creating a mouthpiece that does not cover the user's molars or premolars, yet which creates an interocclusal gap when worn.

Abstract: The present application is directed to a mouth guard to protect the user's teeth and/or jaw.
