Abstract: A dental appliance to reduce the effect of facial age lines has a U-shaped planar part or piece with a curved central part and two generally straight leg parts extending therefrom. The planar piece has an upper surface that is continuous and generally unobstructed. A lower surface of the planar piece has an elongated flap that extends along the outer edge of each leg of the planar piece and engages the outer sides of the lower teeth of the user so as to align the appliance during fitting and use. The lower surface is continuous and generally unobstructed, except for the flap. Bite pads are located on the upper and lower surfaces of both legs in the unobstructed areas. A wing extends upwardly from the top surface of the planar piece at its outer edge where the legs extend into the curved central part on each side. These wings engage the inside of the lips in the areas of the nasolabial fold lines and are preloaded to push them outwardly during use.
