But this week it was turned into a dentist's office thanks to the Manhattan Whitening Company, an on-demand teeth- whitening service.

Founded by Dr. Eric Noising, the MWC offers the same treatment you could get at a traditional dentist's office. MWC's $600-per-treatment price tag is comparable, too, Novison told Tech Insider.

The company launched in July, and its client list includes stars like Aviva Drescher and Jill Zarin from "The Real Housewives of New York City."

If you're in the New York City area, you can order a treatment on the MWC website and Novison or one of his associates will whiten your teeth anywhere that's convenient for you — even a living room in a tiny New York apartment.
