Custom Dental Prosthetics
If you really want to radically change the appearance of your gums and teeth you will have to make a set of custom dental prosthetics. This is a complicated process that borders on bridge work. By the way it is illegal to practice dentistry without a license. You should never think about wearing any of these things for any extended period of time. If you are interested in this process you should start with good information on the subject. Books which have sections on dental prosthetics are: Stage Makeup by Corson, Grande Illusions by Savini or Special Makeup Effects by Kehoe. We carry the professional level materials to make these items, but we don't sell them to kids unless an experienced adult certifies that he or she will be present and supervise their use.
