A multi-purpose dental applicator including a handle and an interchangeable removable member which can be a yoke supporting a length of dental floss, a toothbrush, a spiral wound wire tooth cleaning brush, a rubber tip gum massager, or a length of abrasive tape. The handle has an elongated shank for gripping purposes and a head piece having a receiving cavity for receiving the shank of the interchangeable removable member. The handle further incorporates threads on the outer surface of the head surrounding the receiving cavity. In the preferred embodiment, the receiving cavity is an opening extending into the body of the head in a generally inverted frustum shaped configuration which then extends into a spherical shaped cavity and thereafter extends into an arcuate section having the circumferential length of approximately twenty degrees to either side of the vertical or longitudinal axis of the head. This cavity is designed to receive a specially designed shank which design is common to all of the interchangeable removable members. The handle further comprises a slidable and threaded collar which can be slid onto and screwed around the opening to tighten the interchangeable removable member to the handle.

A multi-purpose dental applicator comprising: a. a handle member further comprising, (i) an elongated shank, (ii) a throat section extending from the elongated shank and extending to a head section, (iii) the head section including an internal opening at the top of the head section leading to a generally inverted frustum shaped cavity which in turn is contiguous with and leading to a spherical cavity which in turn is contiguous with and leading to an arcuate cavity within the head section, (iv) the outer surface of the head section having threads thereon, (v) a slidable collar which partially rests around the throat section of the handle and having internal threads for mating engagement with the threads on the head section; b. an interchangeable removable member further comprising, (i) an elongated shank, (ii) the elongated shank ending in a spherical ball at one end, (iii) a stem extending from the spherical ball at a location diametrically opposite to an attachment point of the elongated shank and the spherical ball and in alignment with the elongated shank, and (iv) a dental applicator part integral with the elongated shank at the end remote from the spherical ball; c. whereby the interchangeable removable member can be removably retained within the head of said handle by insertion of the shank, spherical ball and stem into the head through the opening in the top of the head while the collar is resting partially on the throat of the handle, with the stem resting in the arcuate cavity, the spherical ball retained within the spherical cavity and a portion of the shank resting within the inverted frustum shaped cavity, and the collar is then threaded onto the head to thereby tighten the interchangeable removable member into the head.
