A dental tool including a dental prophy angle and a dental prophy angle adapter is provided. A dental prophy angle includes a housing and a rotor. The dental prophy angle adapter can include a drive shaft with a tip. The drive shaft of the adapter can be coupled to a gear at the same end of the tip with the rotor of the prophy angle being configured to receive the tip. Further, a slidable sleeve can extend over a portion of the drift shaft so that the slidable sleeve becomes automatically retracted upon engaging a shoulder of the housing resulting in the gear of the drive shaft being positioned beyond the end of the slidable sleeve.
