Colgate Optic White Overnight Teeth Whitening Pen, Teeth Stain Remover to Whiten Teeth, 35 Nightly Treatments

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 packagingNegatives:-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!

I was pleasantly surprised that I saw decent results after very first use. Have only done it one other time since initial use, left my teeth ever so slightly sensitive after, so didn’t want to push it by using too frequently. I think it’s worth the buy! Very easy to use, and being able to apply and go straight to bed to let it work its magic is what sucked me in. Doesn’t leave any weird taste in your mouth and dries on your teeth pretty quick.

Overall, the pen is fine. I’ve seen results, so it’s not like it’s a product that doesn’t work. However, my results have been subtle. What I don’t like about it is it’s very hard to know if each tooth is getting the right/same amount of product compared to the other teeth around it. Also, even though I have followed the instructions for clean and care after use, the tip has gotten gunky contributing to some applications seeming uneven. I think if you have one or two teeth that are more stained than the rest, you should buy this product to target those specifically. But if you are looking for a product to do a basic whitening for all teeth, I would look elsewhere. My husband just got the strips + light by Crest and has been impressed.In summary: this product is fine but I won’t choose it again!
