Human Tooth Model KitThis anatomically accurate 7 1 2" tall plastic model of the human tooth opens to reveal all the nerves inside. It's eight times the size of a normal tooth, so it looks great on a shelf or in Gary Busey's mouth. If you drop it, it will break. So, if you want the tooth, make sure you can handle the tooth. Assembly required. Must be painted to look like picture, paint and cement not included. For ages 10 and up.
