Review on iSmile Teeth Whitening Pen - 35% Carbamide Peroxide, Sensitivity-Free, Portable, User-Friendly, 2mL, 2 Pack by Myron Brooks

I've been using the whitening pen for about 3 weeks and have noticed a positive difference. I use it twice a day and it really is as easy as they say. It applies cleanly, dries quickly and is absolutely tasteless (I can tell you that). I have a front tooth with a cap that doesn't respond to bleaching or whitening products and doesn't stain. Therefore, it is noticeable that my other tooth has a darker shade. This product DEFINITELY helped solve this problem as I have used it on all my other teeth except for my capped front tooth. So far I am very happy with the results because all of my other teeth are much closer to that freak in front and I will keep using the pen until there is a noticeable difference. I recommend this product.
