A toothbrush for cleaning the lingual areas of the teeth while the user's mouth is substantially closed. The toothbrush includes a flat, wide connecting portion extending between the handle portion and the head portion of the toothbrush. The connecting portion allows the user to substantially close his mouth during brushing of the lingual areas of the teeth. The toothbrush is also provided with bristles extending outwardly to form a wide brushing area for simultaneously cleaning the upper and lower teeth.

A toothbrush for cleaning teeth and gums, comprising:
- an elongated handle portion having a first free end and a second end with a predetermined length extending longitudinally in a first direction between said first and second ends of said handle portion, a predetermined width extending in a second direction substantially perpendicular to said first direction, and a predetermined thickness extending in a third direction substantially perpendicular to said first and second directions;
- a substantially flat connecting portion having a first end and a second end with said first end of said connecting portion being integrally coupled to said second end of said handle portion, and having a predetermined longitudinal length extending at least approximately one inch in said first direction, a predetermined thickness extending at least approximately no greater than one-sixteenth of an inch in said second direction and a predetermined width extending at least approximately one-half inch in said third direction, said thickness of said connecting portion being less than said width of said handle portion, and said width of said connecting portion greater than said thickness of said handle portion;
- and
- a head portion having a first end and a second free end with said first end of said head portion being integrally coupled to second end of said connecting portion, said head portion having bristles extending outwardly generally in said third direction from said head portion so that said predetermined width of said connecting portion extends substantially in the same direction as said bristles of said head portion.
