Colgate Optic White Express Teeth Whitening Pen, 7 Day Treatment, 0.08 oz | Whiter Teeth in 1 Day, Designed for No Tooth Sensitivity, Safe for Daily Use, Teeth Stain Remover, Enamel Safe

I recently tried the Colgate Optic White Express Teeth Whitening Pen, and I have to say, I’m impressed. Whitening products can be hit-or-miss, but this one genuinely delivered. The first thing I noticed is how easy it is to use. You just dry your teeth, apply the gel with the pen’s precise applicator, wait for an hour, and then brush off with water. I’m usually skeptical about “quick results” claims, but after the first use, I could see a subtle difference. Another big plus for me was the lack of sensitivity. I’ve tried other whitening products that left my teeth feeling sore, but with this pen, I didn’t experience any discomfort. It’s also enamel-safe, which was reassuring. I love that it’s small enough to throw in a bag if you’re traveling or out and about. I don’t need to worry about trays, strips, or extra steps. For anyone looking for a convenient and effective whitening option, this pen is worth trying. It’s easy, it works, and it doesn’t leave you dealing with any of the typical downsides!

I recently tried the Colgate Optic White Express Teeth Whitening Pen, and here’s my honest take. The pen is easy to use and has a convenient applicator that makes it simple to apply directly to the teeth. I noticed some whitening effects after just a day of use, which was impressive. After using it for the full 7-day treatment, my teeth appeared noticeably brighter, though not dramatically white. One thing I liked is that it’s enamel-safe, and I didn’t experience any sensitivity, which is a big plus. The gel has a mild taste and doesn’t leave any aftertaste. However, the whitening results weren’t as dramatic as professional treatments, but it’s a solid, affordable option for anyone looking for a subtle improvement in their smile. Overall, it’s a great product for those seeking gradual whitening without irritation. Would recommend it for light stains or a slight brightness boost.

the brush gets stiff making it hard to apply but it does work well

It is easy to use. It is gentle on teeth. It does whiten but be aware it is temporary. Overall it is a nice way to whiten teeth before date night or anything.

This does work well. I use to use the same product, but it was the overnight formula, which I liked being able to get the whitening effect for the entire night, where as this new formula is only for 1hr. Not sure if it is more potent, or why this has changed, but it works regardless. They also changed the tube from a metered push button with click, (which fails easier) to a simple dip in brush. I drink a lot of coffee and I do smoke, this whitener does make a noticeable difference in shade/color on the very 1st use. My teeth are somewhat sensitive, and there has never been any negative effect on my teeth using this. I recommend it, as well as this seller that shipped fast.

This works great! I'm not a smoker, but I do drink a lot of tea and coffee. Even though my teeth have never been very white even as a kid. I drink a lot of tea and coffee and I got those stains you get in-between your teeth that brushing alone couldn't get. I wasn't expecting much, but there was a significant difference. It seems like a lot of money at first, but once the stains were gone, I felt it was worth it.

BEWARE OF THIS PRODUCT!!! I accidentally turned the open pen upside down and the whitening formula poured out all over my hand and fingers. It dried quickly like on your teeth and I couldn't scrub it off as it kept burning my hand and fingers. Very poor pen design. It should be totally encapsulated with a brush on the end. Unsafe product, caustic.

The Colgate Optic White Express Teeth Whitening Pen is a fantastic product for anyone looking to enhance their smile effortlessly. Its compact design makes it perfect for travel, and the application is incredibly easy—just twist, apply, and go! I noticed visible results in just a few days, making it a quick and effective solution for whitening. The formula is enamel-safe, giving you peace of mind while brightening your teeth. Plus, it’s a great option for touch-ups before special occasions. Overall, it’s a user-friendly and efficient way to achieve a brighter smile!
