"When I first heard about Dr. Wang's program, 'Whitening For Life', I thought it was too good to be true. At my cleaning appointment, I payed a small fee of $99 for custom, take-home bleaching trays and top-of-the-line bleaching material. She gives me new bleaching material free of charge, every time I come in for my 6 month cleaning! I still can't believe I've gotten such a bright smile, at such an affordable price." T.S.
