  • Patent number: 8206231
    Abstract: An improved novelty teeth device for use with a user's teeth movable between a first concealed position and a second visible position. The novelty teeth device has a pair of spaced apart tooth wells for receiving the user's teeth. Between the tooth wells is a central lever element that connects and interacts with two rods, each of which is inserted across each tooth well. The other end of each rod is connected to a curve arm. At the distal end of each curve arm is one or more teeth elements. When the central lever element is pivoted up or down, it rotates the rods, which causes the curve arms to move up or down, concealing or revealing the teeth elements, respectively. A moldable putty can be used in the tooth well to improve comfort to the user.
