This handy little pen was on our team's radar even before it went viral on TikTok because On the Go is everything you want — pocket-sized, inexpensive, easy to use, and, of course, it works. When applied twice daily after meals, this pen delivers a brighter smile in just one week. As observers of the aforementioned TikTok note, you may even see results after the first few strokes.

Made without silicon, aspartame, or phosphate, users report no increase in teeth sensitivity after recommended use, making it ideal for most mouths. Complete and compact, the Go Smile On the Go pen is extremely portable in case you need a quick touch-up before a big meeting, and pairs with a larger blue light treatment for those looking to get the most out of their whitening experience.

Amazon reviewers agree they see a difference when they incorporate this teeth-whitening pen into their routine. "Used this twice daily for eight days before an important in-person meeting. I hadn’t done much with my teeth the past year-plus beyond regular brushing. This whitened my teeth right back up and I was proud of my smile being back to normal and then some!! Results were impressive," says a 5-star review.

Curious about what teeth-whitening pen the pros actually recommend? I got you!

Silver likes this Colgate whitening pen for its effectiveness and reputation as a trusted dental care brand. "Colgate's whitening pen is designed to target and reduce surface stains on teeth, making it an efficient choice for enhancing your smile. Its effectiveness lies in its carefully formulated whitening gel, which is safe for dental enamel while still delivering noticeable results," she explains.

Nearly 25,000 Amazon reviewers have given the Colgate Optic White five stars, and it's not hard to see why. This pen can dramatically reduce even the most stubborn of stains overnight with its fast-acting treatment, which claims to reduce stains in just a week, while using 3% hydrogen peroxide.

Speaking of reviews, here's some insight from a popular 5-star Amazon review, "After a week of consistent use, I could see a noticeable difference in the color of my teeth. They were definitely whiter, and the improvement was apparent even to my friends and family."

Plus, the precision tip means you won't have to worry about bumping your gums, leading to less irritation and sensitivity.

Dentist Dr. Latecia Miller, DDS, also likes the above-mentioned Colgate teeth-whitening pen and these nifty Crest Whitening Emulsions.

"Crest is arguably the biggest brand in teeth whitening and carries a lot of trust behind the name with all the products they release. It helps that their products also fall into the convenient, easy to use, and affordable category making them easy to trust and hard to pass up," she says.

The dentist-approved brand created its first-ever hydrating whitening treatment that combines peroxide droplets with a hydrating base to help minimize sensitivity.

Subtly whiten coffee, tea, wine, juice, berry, and even tobacco stains with this nifty teeth-whitening pen. What's most unique about this pick is that it's free of harsh bleaching agents, and it contains zero parabens, silica, triclosan, sulfates, known allergens, and animal by-products. Its formulation is so gentle that Supersmile promises it cosmetically enhances your natural teeth, along with dentures, veneers, or bonded teeth.

After coating the enamel, it helps prevent stains from anything you consume afterward for up to six hours. And don't just take the brand's word for it — trust the online reviews. "This is great, it protects my teeth from my blackberry staining and makes them even whiter," says a 5-star review on Supersmile's site. The reviewer adds their favorite feature of this teeth-whitening pen is the easy of use. "Just brush it on and you are done."

While some whitening pens contain chemicals that may irritate sensitive teeth, others include ingredients that could actually be beneficial. Smile Briter's pens not only don't agitate sensitive teeth, but they also include Xylitol, a non-fermented sugar, in their formula.

And before years of candy-induced cavities make you wary of the “sugar” and “teeth” word combo, studies have shown that Xylitol can actually help strengthen tooth enamel!

Amazon reviewers highlight it as winning at-home treatment. One mom gifted her teen daughter this gel pen who she describes as someone who wants their teeth to look perfect 24/7 and has tried a slew of cheap and expensive teeth-whitening products, but is never fully satisfied with the results.

To quote her 5-star Amazon review, "My daughter has been using this for a couple of weeks and you can already notice an improvement. If you are loking for some great whitening gel pens try these out, you know that if they can make a teenage girl happy they must be good."

If you're not looking to invest your time and money into a multi-week process, this simple and affordable pen from Polar can help deliver the post-coffee break brightening you need without lightening your wallet too much in the process.

You'll be able to get more than 20 sessions of 15- to 30-minute applications from this Polar pen, all for under $10. For even faster results, you can pair this super-charged teeth-whitening pen with the brand's polar LED light.

Online reviewers highlight the travel-friendly size that fits perfectly in their bag for post-lunchtime teeth-whitening. To quote a 5-star review, "I left mine on about 25 minutes the first time I did it and repeated the process after three days as I am a heavy coffee drinker and cigarette smoker. The results I have seen are so very impressive and I absolutely love this whitening pen!"

Tarte isn’t just a cosmetics brand — they’re giving it up for the oral care aficionados, too! This vegan formula is great for on-the-spot touch-ups, and will protect your enamel while also giving you a whiter smile.

This teeth-whitening pen earned top marks from Sephora shoppers, but my personal favorite is a 5-star review that highlights it as a fantastic at-home alternative to pro-grade treatments. "I was pretty weary buying this after zoom didn't work and just caused sensitivity, but I'm on day two today and excited to see how much more of my old smoking stains get removed. I'm already seeing a difference," says the Sephora reviewer.

Plenty of teeth-whitening pens seem like they’re easy to transport, but not all pens travel the same. If you’ve ever had an errant cap pop off — or worse, a whole pen get crushed — you won't just be shopping for a new whitening pen, but a whole new bag! That's what makes the Spotlight Oral Care a standout for travelers, since it's not only a durable pen on its own, but also comes with a handy pouch for carrying in a purse and a protective tube for luggage.

Spotlight Oral Care is also a sustainable and clinically effective oral beauty brand created by dentists — meaning that their products are medically proven and full of ingredients that are great for your teeth. In just 5 minutes, this whitening pen can lift the color off stains. It's as close as you can get to professional-grade quality when you're on the go.
