Hi Dr Andrew, hope you are well. What is the difference between Enlighten Whitening and Enlighten Evolution 3 Whitening? I know with Evolution 3 you get the in-surgery appointment on the 15th day, but does this really make a big difference to results generally, as there is a significant difference in price? And do teeth sometimes go whiter than a B1 shade? I’ve heard they can do depending on natural colour of teeth?
Many thanks in advance.
