In emergency situations, moonlight reflected off pearly whites creates a beaming beacon that registers in the canine-visible spectrum of light. With today's Groupon, equip your smile with brightness that definitely will one day save your life: for $45, you get two Whiter Image teeth-whitening sessions at Slick Rock Tanning & Spa (a $99 value).

Each 15-minute session is a safe, effective way to whiten teeth two to six shades. The chair-side procedure uses prefilled whitening trays to baste mouth bones in a hydrogen-peroxide solution that’s painless to use, even for sensitive mouths that erupt in a geyser of tears when they accidentally kill an ant. For an extra-turbo boost to aid in the destruction of stains, the Whiter Image treatment uses a premium-grade blue LED whitening light that penetrates tobacco, coffee, wine, and asphalt stains to reveal your mouth’s most radiant picket fence. The beauty aestheticians at Slick Rock provide state-of-the-art customer service to match the state-of-the-art equipment in the clean, modern spa atmosphere. Healthy teeth are important for making a good impression, as well as for providing concrete proof to your significant other that he or she is not hallucinating your suddenly increased hotness, only your third eyeball.
