A dental instrument delivery system is disclosed that not only provides for the needs of the doctor, but comfortably accommodates the dental assistant. The delivery system comprises a pair of dental units individually mounted on swivels to be positioned about a dental chair. The first dental unit includes a work surface and a control module having a plurality of airdriven handpieces and a three-way syringe mounted thereon. The second unit also includes a work surface along with having various handpieces, such as a syringe, evacuator, and saliva ejector mounted thereon. Each of the swivels supporting a respective dental unit includes a pair of pivotally interconnected legs which are connected to a common pivot point located on a base having a support structure which is positioned below the base of the dental chair. This construction enables the dental units to be moved freely about the chair and also to be easily interchanged from the right to the left hand positions.
