The device comprises two identical cases (14) shaped similarly to a dentists impression tray, which are removable joined to an operation handle with their closed bases (18) pointing toward each other. For use the handle is attached to one or both of the trays (14), the device is inserted into the mouth, enveloping the teeth (12, 21, 22, 29, 35) of either one or both jaws simultaneously. A belt (31), moved by a motion generator accommodated inside the handle and provided with soft cleaning segments (20), is guided by various holding (5, 6, 36) and return elements (8) along the teeth (12, 21, 22, 29, 35) in an oscillatory or linear motion as required.
