With March rearing its head, a white winter in NYC has become a pipe dream. But white teeth? Those won't take a miracle from Mother Nature, just a visit to one of Zen Dentistry's midtown outposts with today's deal in hand. Pay $149 (regularly $699) for a Bright Smile laser teeth-whitening session. You'll relax in a comfy dental chair and look out on a breathtaking view of the city while the office's experienced technicians clean your teeth, apply a whitening gel, and point a gentle blue light at your chompers, making your teeth distinctly brighter and lighter. Who needs powdery flakes when you're such a vision in white?
