A vacuum receptacle and method is provided for accumulating, holding and disposing of liquids and certain solids that are withdrawn from the mouths of dental patients by a suction tube or other apparatus placed in the patient's mouth during dental procedures. The receptacle incorporates a vacuum outlet port to which a vacuum pump line is attached. The vacuum pump line pulls air and dental debris through the receptacle from a waste inlet port which is connected through a hose to the tube in the patient's mouth. A baffle is provided to impact and decelerate the dental debris as it enters the receptacle. Once decelerated, the dental debris falls to the bottom of the receptacle where it accumulates up to a predetermined level whereupon a float assembly activates a discharge pump. The discharge pump is connected to a waste outlet port that removes the accumulated fluid waste via an internal waste outlet tube. In the event the float assembly or discharge pump fails and the waste in the canister continues to accumulate, a vacuum safety float assembly is activated by the rising waste. Upon activation, the safety float assembly temporarily disables the vacuum pump thereby preventing further accumulation.
