A toothbrush comprising:
- a body having a proximal end, a distal end, a dorsal side, a ventral side, and a midline distance between the proximal end and the distal end, the body having a first portion that is curved concave continuously relative to the dorsal side from a proximal end of the first portion to a distal end of the first portion, the first portion having a midline distance from the proximal end of the first portion to the distal end of the first portion that is at least about twenty five percent of the midline distance of the body;
