These dentists-turned-entrepreneurs invented a clever way to choose the lowest price you want to pay for dental treatment - here's how it works

First, you pick the dental treatment you need.

If you're unsure of which service is right for you, you can use Smylen's self-diagnosis tool to get a general idea of the treatment you might need.

Then, pick the fee you want to pay for the service you picked and place your bid.

Smylen connects dentists and patients through relevant area codes. Currently, Smylen provides its services only within New York City, but Giddon says he plans to expand Smylen's offerings to different parts of the US later this year.

After you enter your credit card information, you'll be matched with a dentist. If the price you picked is an acceptable bid for a dentist, your card will be charged the moment you match. In this instance, my bid for a $99 whitening service matched with a Brooklyn-based dentist.

Because Smylen's price point tool is based on bids, you may have to enter several different amounts before you match. Once you do, you'll be prompted to pick a time that works.
