Aquafresh White trays are not really bad.

My teeth did become a little whiter, but not many people noticed it. it's okay. Next time I will try something new, but if it doesn't work better I will definetly go bach to this product.

My teeth did not become sensitive, which is always a plus. But the trays were kind of hard to keep inside. If you can sit quiet for 30 minutes then this should be no problem for you because if you don't talk you can hold train inside with your teeth.

The only problem is there is too much saliva and you can't swallow it because the medicine seeks out and it's hard to manage....
