It really works!

Now that I'm getting on the cups of tea are taking their toll. I purchased this because I didn't want to spent lots of money at a dentist.

All I can say is, it works and really well. If you have sensitive teeth it might cause some pain as it is strong stuff otherwise it really does lift the stains.

My teeth not only look whiter but feel cleaner! Much cleAner than using a whitening toothpaste and mouthwash ( which I do)

All you need are the trays and toothpaste. The rest I have never opened and I'm on my 3rd packet in about 3 year.
