The depraved dentist, D.K. Molar, and his nurse, Nova Caine, have crafted a dastardly scam: after putting their patients to sleep with nitrous oxide, they remove the gold crowns and replace them with fakes made of fool’s gold. The unsuspecting patients are none the wiser. That is until Dr. Molar’s new receptionist, the lovely Flossy Dailey, starts chewing over some of the strange happenings in the office. With Phil de Tooth, an upstanding young dentist, Flossy discovers Molar is prospecting for more than overbites.
