Wisdom Tooth appears in the Elmo's World episode "Teeth," where she tells Elmo all about what teeth do, even if it is a bit of a grind. Sporting a pair of glasses and a mortarboard, she explains the functions of teeth such as biting, chewing, and mashing food.

The puppet was previously seen as Tooth in a "Here Is Your Life" segment with Guy Smiley.
