The toothbrush has a support arm for an oblong head (12) articulated on one end (4) of the handle (2). It pivots between an open position and a closed position with the head fitted into a hollow (10) near the curved free end of the handle (6). The curve of the hollow corresponds to that of the head. A second curved arm (16), supporting a head (14) with a small conical brush, pivots on the free end of the handle. When closed it is held in a second hollow (18) in the handle and its arm fits into the first hollow.
