This 'very effective' Colgate teeth whitening pen works while you sleep — and it's down to $20

What is it?

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

Why is it a good deal?

Having your teeth whitened professionally just once can cost a pretty penny, whereas you'll get 35 nightly treatments out of this $20 pen — a price we haven't seen since Prime Day. And, since time is money, the fact that it'll do the job while you're asleep is the cherry on top!

Why do I need this?

The potent formula, made with 3% hydrogen peroxide, is vegan-, sugar- and gluten-free. It creates a film on your teeth while you count sheep, which you can then brush away in the morning. It’s so easy to apply, too — just dry your teeth, click the pen to deposit the product onto the brush and coat your chompers. No need to fiddle around with messy white strips or take time out of your busy schedule to apply.

What reviewers say

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

One wrote: “I could never use those whitening strips for more than a day because of sensitivity. This product gives me little to no sensitivity, and I saw a difference in my teeth after the first use!”

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

Even dentists notice a difference! “You can most certainly see the results working,” shared one shopper. “My dentist noted how much whiter my teeth were when I went in for a cleaning!”

Another chimed in: “I never thought I’d write a review on toothpaste but this stuff is THAT amazing. I’ve always used Crest my whole life because I thought it was the best. I’ve been missing out. My dental hygienist recommended this to me and I’m obsessed. Not only did it actually whiten my teeth, but the hydrogen peroxide got rid of my tonsil stones I had (I know...). I’ve tried whitening trays, scrubs and even charcoal powder, but nothing whitens my teeth as well as this stuff! My breath is fresh and the taste is perfect.”

"I found this product easy to use and very effective," shared a final fan. "After the first use, I could see a difference, and after several uses my teeth were noticeably whiter. It even whitened my teeth where my gums had receded. ... The only small negative to this product is that it can be a bit difficult to tell when there is adequate gel on the brush, and to see whether a particular tooth has been perfectly covered. These are not deal-breakers for me, and I will be continuing to use this product."

"I love this dang toothbrush,"revealed a happy reviewer. "In one single session, my teeth are at least three shades lighter and it completely removed the yellowing that I couldn't get rid of between my teeth, no matter how aggressively I would brush. With that much cleaning, I expected some sensitivity but I ate crushed ice about an hour after brushing and there was no sensitivity at all!"
