File this under totally strange cosmetic enhancements. Toothartist.com 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.
