Cavities Suck

So here is something I did quite a ways back.  Probably about 2 years...maybe almost 3?  Either way...I did it for a tshirt design, but it was never made.  I quite like it, it's different than my usual stuff.  You wouldn't know that, of course, as this is the first artwork I've posted, but just trust me.  It's called "Toothache".  I'm fairly confident you can figure it out from here.
