ABSTRACT:
An improved toothbrush enables the user to brush more effectively the front and back of the upper and lower front teeth and vertically on the back teeth with the toothbrush handle perpendicular to the toothbrush allowing a more natural stroke of the hand and arm which will in turn provide for a more effective cleaning of the front teeth. For all other teeth, simply rotate the brush or handle to be in parallel with each other to offer the present day design for brushing teeth. For the parallel, fixed device, offering a round, square or hexagon head design, the ease of operation is created by bristles not only running thinly parallel with the handle as with present day brushes. This device offers wide bristles and accessibility to difficult areas to brush vertically or horizontaly without rotating the head handle. The extra widened bristle design with rows of bristles running vertically and horizontal. Present day toothbrushes have a narrow bristle construction that is limited by the width of the handle. For the switch operated rotating, indexing, swiveling toothbrush head, this device offers instantaneous changing of toothbrush head position with a thumb or finger operated switch. For the twist handle method, this device offers the indexing of the toothbrush head with a turn of the toothbrush handle.
