I think the walk-ins refers to him and this one girl. Like, she walks in and wants a quickie, but he feels bad because his feelings are toward someone else. This song is all about how he regrets falling in love. Now every relationship he's in is never the same. The first girl, the one he loves broke his heart, left him with cavities, just a painful reminded. And took his wisdom teeth, like, not real teeth, but just his ability to make good decisions.
