Abstract
Abstract A dental toothbrush has a brush head comprised of nylon mesh or interlaced or fused loops. The brush head may be arranged in rows and in combination with ordinary, well-known bristles. By varying the design of the interlaced mesh and thickness of nylon, the rigidity of the brush head may be varied for different dental requirements.
