Abstract A dental hygiene teaching tool and storage device is configured as a caricatured head including a lower jaw member and an upper jaw member which is movably positioned on top of the lower jaw member. The forward portions of both the lower and upper jaw members are molded to simulate realistic human teeth. The lower jaw member includes a well for receiving a container of dental floss which is normally covered and concealed by the upper jaw member. The upper jaw member includes a plurality of bores for holding elongated dental hygiene implements such as toothbrushes, mouth mirrors and the like in vertically upright positions.

Claim 1
Independent Claim
258 words
A dental hygiene teaching tool and storage device in the form of a caricatured head comprising: (a) a lipless lower jaw member including a front portion and a rear portion, with a set of fully exposed, realistic, simulated human lower gums being formed in said front portion; (b) a lipless upper jaw member movably positioned on top of said lower jaw member, said upper jaw member including a front portion and a rear portion, with a realistic palate and a set of fully exposed, realistic, simulated human upper gums being formed in said front portion; (c) a set of realistic, orthodontically correct, simulated human teeth, including a set of 16 upper teeth depending from said upper gums of said upper jaw member and a set of 16 lower teeth extending vertically upwardly from said lower gums of said lower jaw member, each set of teeth being symmetrical about an imaginary central axis which divides each jaw into a left side and a right side, with each side of each jaw including three simulated molars, two simulated bicuspids, one simulated cuspid, one simulated lateral tooth, and one simulated central tooth; (d) a pair of eyes and a nose formed on the front portion of said upper jaw member above said upper gums to provide said caricatured head with a whimsical facial appearance; (e) a well for receiving a container of dental floss; and (f) a plurality of elongated bores extending through the rear portion of said upper jaws for receiving a plurality of vertically upstanding, elongated dental hygiene implements.
