HB 766 -- Teeth Whitening Sponsor: Grill This bill requires all teeth-whitening formulations to be prescribed and dispensed by a licensed dentist. Application of whitening formulations may be done by licensed dental hygienists and registered dental assistants, but only under the direct supervision of a licensed dentist. Any person who takes dental impressions or performs any part of the teeth-whitening process without being under the direct supervision of a licensed dentist will be deemed to be engaging in the practice of dentistry.Copyright (c) Missouri House of Representatives
