Don't "pass" on these Bitemares Horror Undead Teeth like you did to enter the afterlife. This newest line of flexible costume teeth sculpted by Hollywood FX Teeth Specialist, Aaaron Globerman are made to look as authentic as possible. Undead teeth come with upper and lower teeth and are made from soft flexible plastic. They are easy to apply using the plastic pellets provided with each set. Just place the plastic pellets in hot water to soften then attach to the back of the Undead teeth and then fit to your nice living teeth. Your mouth is now offically Undead.
