What do Princess Diana, Amy Winehouse, Abraham Lincoln, Elvis, David Letterman, Tiger Woods, and George Washington have in common? You can get them all “tattooed” on your teeth. Heward Dental Lab of Sandy, Utah offers a (thankfully) unique service. Tooth tattoos. To compliment your attractive new dental body mod, maybe you’d like to try some DIY laser-etching on your nails. Way cooler than just wearing black nail polish (Please, how eighties!). Of course you’ll need to build your home-made laser cutter to complete the task. Careful though, all this body-modding can be addictive.
