Abstract: The interproximal toothbrush includes an appliance body and neck with a nozzle member having a nozzle tip shaped to fit into interproximal teeth spaces. Bursts of air or air/liquid mixture are generated, exiting through the nozzle tip. A helix member or, alternatively, a spring, is supported within a channel in the nozzle member. The helix member is free to rotate as air or the air/liquid mixture is moved through the channel. A set of bristles is attached to a forward end of the helix member, so that it rotates with the helix member. Alternatively, a set of bristles is attached to the distal end of the spring so that successive bursts of air or the air/liquid mixture produce an in-and-out movement of the set of bristles toward and away from the teeth.
