I have used so many different whitening products from pens, to strips to the professional ones. Obviously the professional ones are the best, just not always affordable. This pen is ok and it "might" whiten your teeth 2 levels which really, I'm not even sure how much that is. This is ok for the price but for a little bit more you can get the white strips which Think work a lot better.

It works like a charming and using it was so much better than the expensive treatment so I definitely recommend that you go and follow my advice put down those keys and go on line and buy this

I love this whitening pen, but I hate the small bottle it came in. I used to not smile in photos but do now. Love it! I would purchase again if a little cheaper
