File this under totally strange cosmetic enhancements. Toothartist.com [1] is an online tooth tattoo parlor. Yep, you heard me, you can tattoo your teeth. Well, kinda. Just choose the design you want (Elvis, a howling wolf, and ex-presidents are a few options, but they will recreate any image you would like for a price). After your dentist sends a mold of your tooth to Toothartist, they will send a custom-tattooed crown back in a few weeks. Quite a process, yes, but if you're into this sort of thing, I guess it would be worth it. I'm dying to know what you think about this.
