Fantastic product! I've bought this product twice now along with the Billion Dollar Smile tooth polish and tooth whitening strips, think it's fair to say this product has totally transformed my teeth! The colour guide makes it easy to track the changes in your tooth colour and you notice changes from the first use. Can't recommend this product enough.

Fabulous product. Bought this as I'm getting old (56) and my teeth are already looking amazing after just two goes. I have sensitive teeth so was a little concerned but definitely no need to be... thumbs up from me!

Absolutely fantastic. I looked up several teeth whitening kits and came across this product Billion Dollar Smile, i read the reviews which were all good so thought why not give it a try. I'm so glad i did what fantastic results, after a couple of treatments i could already see a difference. I'm now on day five I am so pleased my teeth are really white. I can smile with confidence.
