I wanted to try this product as my dentist said it was the one the hygienist used.I bought 5 tubes yes 5 tubes as I saw it on offer at a shop and have used it for 6 weeks twice a day as instructed by the leaflet in the packaging. I can see no difference in the colour of my teeth and think I have wasted time and money on using this toothpaste. I will revert to a supermarket own brand which costs less than a quarter of the price of Beverlyhills formula, I expect the company boss lives there on th vast profit made from this useless product in my opinion!.I wonder how many others have found this product useless?
