No person in this state may sell, offer, provide, or advertise any dental service including the furnishing, constructing, reproduction, relining, or repair of dentures, bridges, plates, or other appliances to be used or worn as substitutes for natural teeth unless the person holds the appropriate license, registration, or permit issued by the board.

The mere delivery of products to an ultimate consumer or person acting on behalf of the consumer for the purpose of transporting products to the dentist who provided the work order is not a violation of this section. This section does not apply to mailings, displays, and advertisements, the primary distribution of which is to the dental profession or its ancillary trades.
