Just to thank you for the work that you do and to let you know that I have been using Shine for a year or so now and that, whilst my teeth are still pretty yellow (too much black coffee + dark chocolate!), they are definitely more opaque and I am fairly sure they are re-mineralising, as pains that I had when biting are much rarer now and more diminished. I have passed on your details to many grateful people
