Abstract
A system for cleaning of teeth and gums and removing food particles from between the teeth includes a motor driven suction pump and a source of liquid. A clamp means forms an air-tight chamber over a few of the teeth at a time and includes two clamp members, each having a cavity with bristles. A vacuum is applied from the suction pump to one clamp member and draws liquid to the other clamp member and through the enclosed teeth.
Claims5
A system for cleaning a set of teeth comprising:
- (a) vacuum means to create a vacuum;
- (b) a source of liquid to be pulled by the vacuum through gaps between the teeth;
- (c) a clamp means to removably form an air-tight chamber over at least two teeth;
- said clamp means comprising a first clamp member to fit on the back of the teeth and a second clamp member fit on the front of the teeth;
- (d) a vacuum line leading from the vacuum means to one clamp member;
- (e) a liquid line leading from the liquid source to the other clamp member;
- (f) control means connected to said vacuum line to intermittently apply vacuum from said vacuum means to said clamp means and to thereby pull liquid from said liquid source around the teeth within said chamber.
- wherein each of said clamp members is a cup-like member having a cavity adapted to face said teeth and each includes a plurality of bristles within said cavity, said bristles having free ends adapted to contact said teeth.
