Abstract: The new and improved mouth guard of the invention comprises a soft flexible mouth guard preferably of flexible polymer, rubber or plastic materials with a channel for one's teeth and a flexible ball filled with a flexible material that is attached to the exterior base of the mouth guard tray. The flexible ball is positioned under the upper two to four front teeth or above the lower two to four front teeth and extends outwardly to provide a flexible barrier between the upper and lower front teeth for the purpose of absorbing tension and pressure when biting and to prevent contact of the poster teeth thus preventing grinding, clenching and dental issues. Both the mouth guard and flexible ball can vary in size and shape.

Abstract: The invention provides mouth guards sized and configured to prevent jaw clenching and teeth grinding and methods of using the mouth guards. One embodiment provides a one-piece mouth guard made of a semi-rigid, springy, flexible polymer that includes an arcuate tray portion having a front, a rear, a top side and a bottom surface, the arcuate tray portion sized and configured to at least partially cover a person's upper tooth set, and an elastic lower tooth set-engaging tab portion extending from the front of the arcuate tray portion, which tab portion, in its relaxed state, further extends downward below the bottom surface of the tray portion and partially rearward toward the rear of the tray portion so that, rearward of the point the tab portion extends from the tray portion, a space is present between the bottom surface of the tray portion and the tab below.

Abstract: An article of footwear has hooks which may be attached to the inner and outer peripheral edge of the sole (e.g., two or more on each side) to secure different strap or upper covering options. The footwear (shoe/sandal) is only functional when the straps/upper covering are attached to the sole of the shoe/sandal via the hooks. The design of the hook provides a securing method to removably connect the straps to the sole of the shoe/sandal.
