Years of yellowing as well as staining from virtually everything you eat, drink and inhale are almost magically erased in the time it takes to get a haircut, a manicure or lunch. In fact, we have clinical studies which prove that the BriteSmile whitening treatment resulted in an average improvement of 8+ shades! You can feel confident in your decision to have BriteSmile dental professionals whiten your teeth. Clinical testing has proven that the procedure is safe and sound. Safety studies conducted at the University of Medicine and Dentistry of New Jersey found conclusively that BriteSmile whitening resulted in no structural change in teeth, no adverse impacts on fillings and no softening of tooth enamel. And senior researchers at New York University confirmed these study results.
