According to various embodiments, a dental prophylaxis angle is provided that includes including a content lumen within the body, wherein the proximal end of the body is attachable to a concentric drive dental handpiece and the distal end of the body includes a denial tip and a content portal proximate the dental tip. The dental prophylaxis angle can also include a collapsible container disposed within the content lumen and in fluid communication with content portal. The dental prophylaxis angle can also include a reciprocating advancement mechanism including a gripping section slidably attached to an exterior surface of the body and at least one member extending through the body and into the content lumen in communication with the proximal end of the collapsible container. When sliding the gripping section proximally along the longitudinal axis of the body the member at least partially compresses the collapsible container in the distal direction.
