A dental device to be placed in the oral cavity between the lower teeth and the tongue for use as a combined saliva/fluids ejector and tongue deflector/retractor in dental treatments, comprising: a substantially flat head portion with hollow tubing on a portion of its periphery, and suction holes (preferably oval-shaped and protected from soft tissue entrapment by raised ribs) and in communication with the hollow tubing； a body portion provided with a bore and a ratchet mechanism, the bore in communication at its upper end with the hollow tubing and at its lower end with a suction system； and an arm having a collar adapted to adjustably engage with and disengage from the teeth of the ratchet mechanism. The cross sections of the collar and ratchet mechanism portion of the body are essentially square in shape.
