My teeth were very yellow to start and so aren’t white but definitely less yellow. I have used the take home kit for 2 evenings and can’t see any further improvement but I will continue to use for a further 5 days to see if helps. Location is a bit odd but the actual building is nice.
My teeth appeared much whiter after the treatment, but this faded a little over the next few days. The fact that they give you the tubes to continue the process at home is great at that seems to be working better. Good value for money, but it may be worth just buying the tubes.
