The tooth gap cleaner consists of a tip (1), designed to be inserted partially between the teeth, connected to a driven base (3) by an intermediate section (2) with a different degree of flexibility to the tip and base. The tooth gap cleaner consists of a tip (1) preferably 15 - 18 mm long and designed to be inserted partially between the teeth, connected to a driven base (3) by an intermediate section (2) with a different degree of flexibility to the tip and base. The intermediate section can be made from a material with a different coefficient of elasticity, a different geometrical shape, or a combination of the two. It can be compressed axially and made in the form of a spiral spring or bellows. The base is connected to a motor which vibrates the tip preferable at about 250 Hz. |
