Abstract: Common toothbrushes are known as simple units designed for simple use. In this invention, a compound toothbrush is formed by two distinct toothbrushes, one of which closely fits within the partially hollow frontage of the other such that both brushes together compose one single toothbrush of common type for regular use, and they may be manually disassembled for separate use of the inner and specially designed brush to efficiently and safely cleanse the crevice between gums and teeth. This compound type of toothbrush also provides additional facilities for alternate and appropriate use of the two brushes for dental cleaning after light meals and snacks, etc., as well as for thoroughly cleaning both brushes after their use by brushing each other.
