Brush and masseur for interproximal dental cleaning

Claim 1

A tooth brush assembly capable of cleaning and massaging the interproximal dental areas, which comprises: a motor driven tooth brush handle which includes an output drive and means for rotationally oscillating said output drive; an arm detachably connected to said output drive of said handle; and a relatively small rotationally symmetric brush detachably connected to said arm and so constructed and arranged to be inserted into said interproximal areas of the teeth during use, wherein the arm and consequently the brush rotationally oscillate about an axis coaxial with said output drive of said handle to facilitate the cleaning and massaging operation, the rotational oscillation of the brush being physiologically acceptable to the tissue of the gums and provides relatively equal stimulation in one direction and a reverse direction which produces a more equalized blood vessel stimulation as well as increased crevicular fluid flow in the sulcus of the tooth distal to where the stimulation is being applied as well as that of the mesial tooth, the angle and torque of the rotatably oscillating brush being capable of being changed simultaneously according to gum sensitivity so that the stimulation is not deleterious to the interdental tissue even at maximum torque and angle.
