ABSTRACT:
A toothbrush has a bristle bearing head terminating the supporting stem thereof which extends from a handle. The head is disposed with its major axis at right angles to the length of the stem providing lateral extensions having bristles arranged for interproximal and free gingival margin engagement of both the maxillary and mandibular teeth. The supporting stem has a portion adjacent the head offset from a handle connecting end, the latter having a snap-in bearing connection with the handle providing easy separation and assembly and relative rotation of the handle with respect to the stem and head.
