From Season 9, Disguised as a dentist, Guy surprises a tooth at a dentist's office. The tooth is reunited with healthy food (represented by Carl Carrot and Melvin Milk), his dentist, and toothbrush/toothpaste pair Bristly and Pastey. BTW, doesn't the dentist sound like he was voiced by Brian Muehl? Another thing, the tooth looks like he was made out of a cute little plush doll.
