A device for aiding and encouraging a child to brush his or her teeth regularly. The device is provided with a pair of nonrotatable shafts each of which mounts seven rotatable blocks shaped like a molar tooth, each block representing either the morning or night of a particularly day during which a child should brush his teeth. The front surface faces of the blocks form a frowning mouth with dirty teeth, while the rear surface faces form a pattern of a smiling mouth with white teeth after all of the blocks have been rotated 180 degrees. Each block is rotated to expose a portion of the smile and to remove a portion of the frown after each tooth brushing in the morning and evening of each day.

A device for aiding and encouraging a child to brush his teeth, comprising; a mounting frame; a pair of shafts nonrotatably mounted by said mounting frame; a plurality of independently and individually rotatable, spaced-apart blocks each mounted for independent and separate rotation about a respective one of said pair of shafts; each said shaft being mounted horizontally by said mounting frame, said shafts being mounted parallel to each other and vertically spaced apart; each said shaft mounting a plurality of said blocks for said independent and individual rotation in spaced-apart relationship; said blocks thus defining a first row and a second row, said rows being positioned very close to each other; and each said block comprising an upper concave exterior surface and a lower concave exterior surface, so that the first row of blocks may be positioned very close to said second row of blocks and allow for the independent and separate rotation of each block with respect to the juxtapositioned block in the other row; each said block having a front surface face and a rear surface face; each said front surface face comprising a printed design forming a portion of a frowning mouth; and each said rear surface comprising a printed design forming a portion of a smiling mouth.
