A dental suction tool has a disposable sanitary plastic suction tip to prevent cross contamination from one patient to the next. The suction tip is formed as a generally cylindrical hollow tubing and made of disposable plastic material. One end of the suction tip has at least one beveled section along an outer wall surface of the suction tip so that the suction tip can be properly aligned in the dental suction tool. Alternatively, one end of the suction tip has at least one recess that is adapted to cooperate with a keying element in the dental suction tool to properly align the suction tip in the dental suction tool.
