Brighter.com, launched in May 2011, allows users without dental insurance to make informed decisions about their dental care by offering price transparency and discounts up to 60% on their dental procedures.

The additional capital from Benchmark and Mayfield Fund will fund a number of key business growth initiatives, including consumer marketing and the continued development of Brighter's network of dentists, according to the company.

This round of funding comes after a seed funding in January 2010 and series A funding of $5 million in December 2010, both led by Mayfield Fund.
