Keep up the repetition if you expecting great results
I was skeptical at first after trying many other products such as mouthwash scope Crest whitening strips you name it I've tried it even the ultraviolet kits that come at Walmart and it seemed like none of them didn't work yeah your teeth may get white but the black would remain on your teeth and would never go anywhere so I gave this a try and literally in 3 weeks I've seen a dramatic difference in my lower teeth where the black would rest just above the gum line on the bottom of the tooth it literally disappeared
