V34 is a post-whitening treatment that restores brightness and neutralises yellow tones on the tooth surface. It works to brighten teeth by utilising colour correcting technology. By counter-balancing the different hues in your teeth, V34 conceals stains and improves brightness. V34 works to brighten teeth by utilising colour theory technology. By counterbalancing 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. Colour correction all starts with the colour wheel, where purple and yellow are complementary colours opposite each other on the colour wheel. Applying purple onto your teeth neutralises yellow undertones by cancelling them, giving your teeth a perceptively brighter shade of white. V34 is not a chemical whitening treatment and doesnt make any pertinent changes to your teeth, so it is safe to be used on dental work.
