Colgate Optic White Overnight Teeth Whitening Pen, Removes Years Of Stains In Just 1 Week When Used As Directed,Teeth Stain Remover to Whiten Teeth, 35 Nightly Treatments, 0.08 Fl Oz

I tend to write long reviews, so here’s a quick list of positives and negatives of the whitening pen. This may also answer some questions you have about using the whitening pen: Positives: -Actually whitened my teeth! -No bad taste -No irritation/pain -Easy to apply -Nice packaging Negatives: -Did not last as long as the box said it would (lasted 1.5 weeks instead of the 30 usages the box promised) -You have completely to dry off your teeth and then paint on the solution on each individual tooth (I personally didn’t mind this. It just took a little while to do) -If you paint over wet teeth, it will ruin the brush -The solution easily clumps up in areas on teeth after it dries (this didn’t bother me much, but thought it was worth mentioning) Okay so here’s my more in depth review: I’ve tried just about every whitening toothpaste on the market, charcoal, baking soda, and more, with no results. I heard about this pen and thought I’d give it a try. I was a bit nervous because I can have sensitive gums, but I felt no irritation whatsoever! The pen lasted exactly a week and a half before I used it all up (so it did not last the 30x stated on the box!). In that time, I can honestly say my teeth look whiter! I was pleasantly surprised. Believe me, the yellow on my teeth was stubborn! I may purchase the pen again to whiten my teeth even more. However, I noticed a few things about the pen that might be considered negatives to some people. First of all, you have to COMPLETELY dry your teeth before “painting” on the whitening solution with the pen. Otherwise, the solution gets all clumpy and dries up on the brush, which will ruin it. Also, be aware that the pen paints this solution on your teeth and sort of leaves a thin film/coating over your teeth overnight. The solution doesn’t have a taste or anything, but you will definitely want to brush your teeth in the morning to get it all off. Also, be aware that the solution will clump up in places on your teeth when it dries. I was not aware that that was how the pen works when I bought it, but looking back, I noticed that most of the negative reviews focused around the white clumpyness of the solution on your teeth. This honestly didn’t bother me much, though it was a little bit of a hassle to dry off my teeth and get an even coating on each tooth. Additionally, you will only be able to whiten your front teeth, as it is to hard to dry off and paint the teeth at the back of the mouth. Overall, I am pleasantly surprised and impressed by this whitening tool. I’ve tried so many different things and this is the first that has worked! If you are okay with the few “negatives” than definitely purchase this product! I would purchase this again! As a note, I tried to take before and after pictures but because of bad lighting, they didn’t turn out. But I did see a huge improvement in my teeth’s whitening!

Wasn't sure if it would work since I've had the stains for a long time. I got the pen just after lunch. Tried it right away. Couldn't wait until later. Applied the gel to the first 8 teeth on the top-front and the other 8 at the bottom-front. Took a while and quite a few clicks to realize that the gel was on the brush already. The white gel did not take the color right away on the teeth. But, I could feel a thin layer. Kept my lips open with the teeth clenched. Stayed inside my office so people wouldn't question me about the way I looked. Also, I didn't want any saliva getting on the teeth if I talked. I kept blowing air through my teeth, hoping the gel would continue to stay dry. As I was leaving for the day, I couldn't really tell if it worked. It was the first application, after all, and it was for only about 4 hours. The next morning, I am shocked. They are white. I put on double the dosage from the day before and ordered a new pen. At the rate I am clicking on the pen, I am gonna need a new one in just a few days. All in all, a wonderful product. Do use the paper towel to dry your teeth (and not the tissues).

This product is very helpful. Easy to use, mess free, and helps make teeth look whiter. Have used for a few weeks and have seen improvement. Highly recommend this product from Hannah with Waving Palms Teeth Whitening Strips. Thank you!

With diligent and daily use this product seems to whiten teeth. It is somewhat hard to make sure it stays on your teeth but with trial and error it does whiten.

This worked really well and I drink a lot of coffee. I think the price is pretty good compared to whitening strips, and may even be just as effective! I haven't experienced any sensitivity with this pen. The only thing I do not like is that when I wake up with this on, it is a bit icky. Not too bad and it is worth it cause I don't have to use it too often. I highly recommend!
