This teeth whitening pen from Colgate is available on Amazon

What is it?

Coffee, red wine, orange juice – all delicious, but also all can add sparkle to your smile. While professional whitening treatments can turn back the clock, they can also cost hundreds of dollars and require an office visit. Whitening strips work too – they’re a fraction of the price and can, after all, be done at home – but what if you don’t have an hour to spare? The Colgate Optic White Overnight Whitening Pen is designed to be used right before bed and works while you sleep to remove years of stains. Score it on sale for $20 at Amazon.



This handy whitening pen can eliminate over 15 years of coffee, citrus and wine stains in just a week – impressive.

$20 on Amazon

Why is it a good offer?

Getting your teeth professionally whitened just once can cost a pretty penny, while this $20 pen gets you 35 treatments per night—a price we haven’t seen since Prime Day. And since time is money, the fact that it gets the job done while you sleep is icing on the cake!

Why do I need this?

The effective formula with 3% hydrogen peroxide is vegan, sugar and gluten free. When you count sheep, it forms a film on your teeth that you can brush off in the morning. Application is also so easy: just dry your teeth, click the pen to apply the product to the brush, and coat your teeth with it. You don’t have to deal with messy white streaks or take the time to apply.

What reviewers say

The pen has nearly 25,000 perfect five-star reviews. Shoppers love how much easier (and less expensive) it is compared to traditional whitening strips.

One wrote: “Due to the sensitivity, I was never able to use these whitening strips for more than a day. This product causes little to no sensitivity for me and I could see a difference in my teeth after the first use!”

Despite the powerful formula, it is still incredibly gentle on your teeth. “Absolutely amazing,” raved another Five star reviewer. “I’ve only used the overnight teeth whitening pen three times and people are already starting to notice a difference in my teeth. I also have very sensitive teeth and a toothache, but that hasn’t affected my pain at all.”

Even dentists notice a difference! “You can certainly see that the results are working,” he shared Purchaser. “My dentist noticed how much whiter my teeth were when I went for a cleaning!”

Another chimed in: “I never thought I would write a toothpaste review, but this stuff is SO amazing. I have always used Crest my entire life because I thought it was the best. I missed something. My dental hygienist recommended this to me and I am thrilled. Not only did it actually whiten my teeth, but the hydrogen peroxide also removed my tonsil stones that I had (I know…). I’ve tried whitening trays, scrubs, and even activated charcoal powder, but nothing whitens my teeth like this stuff! My breath is fresh and the taste is perfect.”

“I found this product easy to use and very effective,” shared a last fan. “After the first use I could tell a difference and after several uses my teeth were noticeably whiter. It even whitened my teeth where my gums had receded. … The only slight downside to this product is that it can be a bit difficult to tell when there is enough gel on the brush and whether a particular tooth is perfectly covered. For me, these are not deciding factors and I will continue to use this product.”

“I love this damn toothbrush,” a revealed happy reviewer. “In a single session, my teeth are at least three shades lighter and the yellowness that I couldn’t get rid of between my teeth no matter how aggressively I brushed has been completely removed. But with so much brushing, I expected some sensitivity. “I ate crushed ice about an hour after brushing my teeth and had no sensitivity at all!”
