Abstract
The bristles (5, 6) of the toothbrush are implanted perpendicularly in parallel shafts (1) which pass into the case (8). The shaft seat at the front on bearings (7) formed in the case and at the back in a hollow tube (13) in the upper part of the handle (9) where they are joined to the motor. The case and the shafts are removable and interchangeable being released by a button on the outside of the handle. The motor, which rotates in opposite directions, is housed in the handle and can be switched on by a switch on the handle.
