Glide Dental Floss Pig

Saatchi & Saatchi New York ambient for Glide Dental Floss involves a pig. I have no idea what a pig has to do with dental floss. Are they saying that I have a bit of pork rind jammed between my teeth just like this pig is jammed between buildings? Are buildings the teeth of the city? Wow. Far fetched but eye catching then I guess.
