Discus Holdings Inc, Culver City, Calif, has entered into a definitive merger agreement with Royal Philips Electronics. Previously privately held, Discus sells professional tooth whitening products with brands such as Zoom®!, BriteSmile®, and NiteWhite®. The transaction is expected to close in the fourth quarter of 2010, pending regulatory approvals.

“We created Discus almost 20 years ago with the goal of making it easy to improve patient smiles,” said Dr. William Dorfman, founder of Discus Dental. “Since then, millions of people around the world have had smile makeovers using our products and we’ve become a trusted source of clinical solutions for dentists in more than 100 countries and on virtually every continent. By joining the Philips organization, our products will benefit from unprecedented growth opportunities, making tooth whitening even more accessible to a broader audience.”

In the oral care arena, Philips is the maker of Sonicare® line of sonic toothbrushes.

Following the close of the transaction, Discus will become part of the Philips Consumer Lifestyle sector’s Health and Wellness business. Financial details of the agreement were not disclosed.
