Abstract: A cosmetic accessory device for teeth that simulates the appearance of an assemblage of teeth and gum. The device includes a gum portion and a tooth portion shaped and dimensioned to cover the user's upper or lower front teeth. The device is made of a nontoxic, nonirritating, tasteless, odorless, resilient, easily cleaned and chemically stable material that does not stick to natural teeth, gums, or most dental work. In use, the device is held in place by custom-fitted inner projections that match the spaces between the user's own front teeth and (optionally) a shelf extending just across the front teeth. Unlike typical conventional novelty dental devices, the natural teeth and gums are not completely covered, so the device is comfortable to wear and does not interfere with natural speech or bite closure.
