Looking for a quick fix for a brighter smile? Try a teeth whitening pen. "These pens are small, plastic tubes that house a whitening gel," says Dr. Daniel Rubinshtein, D.D.S., a celebrity cosmetic dentist in New York. "They can help improve the color of your teeth by removing leftover stains on each tooth's surface, give visible results quickly and are ideal if you want to add a last-minute touch up on-the-go."
Our top picks:
Whitening pens are just one type of at-home teeth whitening products. "Others include teeth whitening strips that gradually dissolve over the teeth and rigid trays that hold a gel whitening formula on the teeth," says Chiara Butler, a reviews analyst in the Beauty, Health & Sustainability Lab at the Good Housekeeping Institute.
Dr. Rubinshtein explains, "Each of these contain different concentrations of either hydrogen peroxide or carbamide peroxide, the active ingredients used for the removal of surface stains on teeth." Pens generally have the lowest percentage of these ingredients, making them great for touch-ups and short term effects but the results may not last as long as these other whitening categories.
To help you find the best and most effective teeth whitening pens, we've compiled a list of the best dentist-chosen and editor-vetted picks, along with top-rated products online. But your whitening journey doesn't have to end there: Check out our top picks for the best whitening kits, whitening mouthwashes and whitening toothpastes to try, too.

Best Overall Teeth Whitening Pen
Colgate Optic White Overnight Teeth Whitening Pen
Now 35% Off
Pros
- Time-saving
- Works while you sleep
- Minimal pain or sensitivity
Cons
- Formula can harden on teeth or brush
Time-saving and effective, Colgate's pen whitens teeth while you sleep with 3% of the stain lightening ingredient hydrogen peroxide. "The length of time that the gel stays on the teeth is important to provide a better result," says Dr. Max Blondman, D.D.S., a dentist in New York City. "Since the Colgate pen works overnight, the active ingredients have ample time to get the job done." Dr. Rubinshtein is also a fan of this pen, especially because it comes from a reputable brand and has a great price point.
One thing to look out for: While it didn't cause pain, a few reviewers noted that the gel may harden on the applicator brush or your teeth.

The brush has a flexible tip, allowing it to access teeth of different shapes and sizes. While reviewers love the quick results and lack of irritation, a few had trouble using the pen and getting the gel out of the pen even after many clicks.
"This pen works very well, has caused no sensitivity for my teeth and I saw a difference in whitening after the first application," says one Walmart reviewer. "This will be my go-to because I find it works better than any strips or even the trays I got from my dentist."

Crest's teeth whitening pen has a unique spatula applicator that's flexible and easy to use. And it works quickly — you can see real lightening effects in just a single day. "It painlessly whitened my sensitive teeth about two shades over one day — the difference is noticeable," marveled GH Beauty Lab Senior Chemist Sabina Wizemann. "It stayed put, and after a minute or two, I didn’t even feel it on."
The spatula tip isn't for everyone though; a few users commented that it didn't allow the gel to adhere to their teeth well.

Best Portable Teeth Whitening Pen
Go Smile On The Go Teeth Whitening Pen
Pros
- Lower level of active to minimize irritation
- Great for travel
- Easy to apply
Cons
- Not as strong whitening effects
Dr. Rubinshtein recommends Go Smile's pen as it "paints the whitening serum cleanly across the teeth and gives users visible results when used up to twice a day for a week." While it may not give extreme whitening results due to the low percentage of hydrogen peroxide, it can whiten teeth a few shades and is unlikely to irritate teeth. You also can use it alongside the complementary whitening kit, a GH Beauty Award winner, for maximum results.
Reviewers love the portability of the pen — it's ideal for on-the-go usage. "I love that I can carry it in my purse for touchups," says one Amazon reviewer.

Ideal before a big event, reviewers love Tarte's pen for its instant results. "I loved this product," says one Sephora reviewer. "It's so easy to use, has a minty aftertaste and you can literally see a difference in five minutes after applying this." It's also a great choice if you are looking for a vegan option.
Many reviewers love the minty flavor, although a few commented that it was a little strong and unappealing.

Butler loves Snow's multi-functional serum pen: It can be used as part of their whitening kit that includes an LED light or applied solo. "I liked that it was easy to apply and didn’t irritate my gums," she says. "You can leave it on your teeth for just nine minutes or for up to 30 minutes, so it’s easy to incorporate into your routine."
Online reviewers agree that it's gentle and super easy to use. Consistency is key here: One found that their results were minimal when not using multiple nights in a row.

How we choose the best teeth whitening pens
The GH Institute's Beauty Lab rigorously tests all types of oral care, including water flossers, toothpastes, whitening strips and more.
While we haven't yet formally tested teeth whitening pens in the Beauty, Health & Sustainability Lab, we have tested many other whitening products, in which our scientists measure the shade of testers' teeth under standardized lighting before and after using a label-masked teeth whitening product as directed over a specified time period to gauge changes in tooth color. So our experts have a solid understanding of which brands offer the best whitening products on the market, and which formulas are most effective.
The pens on this list are a combination of top picks chosen by top dentists we interviewed and our own Lab scientists, as well as highly rated products from our go-to beauty and health shopping destinations.

What to look for when shopping for the best teeth whitening pens
When it comes to choosing a whitening pen, it's all about the ingredients. "Look for a product with either hydrogen peroxide or carbamide peroxide, the active ingredients used for the removal of surface stains on teeth," says Dr. Rubinshtein. "The ones that have a stronger percentage of these ingredients tend to give the stronger results." Butler also suggests seeking out reputable oral care brands that you know and trust.
Do teeth whitening pens really work?
Yes, but to a limited capacity. "The ingredients mentioned above oxidize and chemically break apart the colored molecules that appear as stains on our teeth," explains Butler. "A whitening pen won’t whiten teeth as quickly as a professional whitening at the dentist’s office. This is because the whitening agents are used at much lower concentrations in the pen, but they will lighten teeth with regular use over time."

How do I use a teeth whitening pen and how long do you leave it on?
(Not so) fun fact: "Most people use the whitening pens the wrong way," says Dr. Rubinshtein. "They also don’t prep the teeth properly beforehand to get the best results." He advises to brush and floss teeth thoroughly first and make sure teeth are dry before using the pen.
"Try to be precise and avoid applying it to your gums, lips or other soft tissues," he says. "A thin, even layer does the trick." It's important to avoid eating, drinking or rinsing the mouth right after to get the best results. Every whitening pen is a little different and has different usage and timing guidelines so always read the instructions before using.
Are there side effects from teeth whitening pens?
"Overusing whitening pens beyond the recommended use can lead to tooth sensitivity and gum irritation and even long-term enamel damage," says Dr. Rubinshtein. "Make sure to wait the correct amount of time and try not to remove it too soon, as this can impact the results."
