Well
The show is really awesome and it's a unique setting. However, I think it would help to take more advantage of this unique setting for the plot. What I mean by that is they're teeth in a mouth, you demonstarted this in the first one by explaining bad breath is caused by teeth farts. Why not take advantage of the setting and incorporate other things involved in the mouth enviornment, such as teethbrushing, flossing, mouthwash, plaque or even cavities (A terminal illness for these guys?) I think it's the setting that makes the show, because if it weren't for that, it'd be like another Newgrounds show with a bunch of guys doing funny and random things which there is plenty of out there. Bring this show to the max!
