An intraoral biofilm control apparatus including a suction unit, a suction chamber positioned within and in communication with an inner space of the suction unit, a tubular connection member operably connected to and extending into the suction chamber, and an angular head member adjustably connected to an upper end of the tubular connection member is provided. The suction chamber, in communication with the suction unit, creates a negative air pressure in an inner space of the suction chamber. The angular head member in fluid communication with the suction chamber via the tubular connection member, contacts and suctions the intraoral biofilm from the intraoral areas into the inner space of the suction chamber when the negative air pressure is created. The angular head member having an angularly curved suction tip configurably accesses the intraoral areas. The angular head member having a suction plate suctions the intraoral biofilm from intraoral tongue areas.
