摘要：An apparatus for brushing an entire arch of teeth at once has a resilient U-shaped housing containing a channel within which the arch of teeth fits. A plurality ofbristles substantially covers the surface area of the channel, and a handle extends fromeach arm of the housing. The channel is shaped whereby the bristles on the edges of thechannel are angled into the gingival sulcus. In operation, the user grasps a handle in eachhand and moves the handles in opposition to each other to move the resilient housing.This causes the bristles to move, thereby brushing the teeth in an effective manner.
