False teeth have been around for a long time. The Etruscans made false teeth out of ivory and bone in 700 B.C. (Travers, B., ed., World of Invention, Gale, (1994) pp. 238-239.)!
Prosthodontics is the specialty that deals with oral prosthetics. Oral prosthetics replace missing teeth in the following ways:
Dentures: Dentures are made when a dentist takes an impression of your jaw. A dental laboratory makes a model of the jaw and carves wax to create a base for the teeth. The wax mold is then removed and the space is filled with plastic
Fillings: Fillings are used to fill cavities. They can be filled using an amalgam or by dental cement made of porcelain.
Crowns (Caps): Crowns are coverings that fit over teeth. Crowns are needed because of damaged fillings and teeth. Crowns also improve the appearance of teeth that are malformed or discolored.
False teeth: These can be used as costume teeth as an actor, actress, or prankster would wear to appear to have the illusion of fangs, crooked teeth, or oversized teeth.
