Our whitening procedure has been perfected through years of experience to give you the whitest teeth the safest possible way. Your gums are carefully protected with a special covering before your dental professional applies our unique hydrogen peroxide whitening gel. Hydrogen peroxide breaks down the molecular bonds making up stains on and in your teeth. The intense light of the Philips Zoom WhiteSpeed Whitening LED Accelerator shining on the whitening gel makes the process work even faster, improving whitening results by as much as 40%.
