A non-sterile dental device intended to be attached to a battery-powered vibrating dental retractor handpiece to function as the retraction hook and vibration transmitter during the administration of a dental injection. The vibration is intended to minimize the pain of the injection by distracting the patient. The device is rubber coated and hook-like to retract the lip/cheek and is simultaneously placed on the gum/palate close to the injection site to transmit the vibrations. This is a single-use device.
