Philips Oral Healthcare (POH) deserves a plaque for fighting, uh, plaque. The company makes Sonicare, a high-tech toothbrush line that uses patented sonic technology, fluid dynamics, and electromechanical design to aid in removing plaque bacteria from between teeth and at the gumline. POH sells its products in the US through warehouse clubs (Costco), mass merchandisers (Target and Wal-Mart), department stores (Sears), and other outlets. It also distributes its products in Canada, Europe, and Japan. Founded in 1988, the company was initially funded by a grant from the National Institutes of Health. It is now a part of Royal Philips Electronics.
