"What is v34? V34 works to brighten teeth by utilising color theory technology. By counter-balancing the different yellow hues in your teeth, V34 temporarily conceals stains and improves brightness. Use V34 after a whitening treatment, daily, or before a big event for a brightness boost. Utilises color correcting technology Color correction all starts with the color wheel, where purple and yellow are complementary colours opposite each other on the color wheel. Applying purple onto your teeth neutralises yellow undertones by cancelling them, giving your teeth a perceptively brighter shade of white. Non-invasive brightening treatment V34 is not a chemical whitening treatment and doesn't make any pertinent changes to your teeth, so it is safe to be used on dental work."
