If you’ve been wishing your smile was a little brighter, you’re not alone. According to recent research conducted by WhiteGlo, a whopping 75% of people are unhappy with the color of their teeth. And while there’s no shortage of various whitening products out there—both over-the-counter and professional options ranging from pens to gels to trays—whitening strips offer one of the easiest ways to score pearly (or at the very least, pearlier) whites. 

Because these strips are breaking down stains chemically rather than scrubbing them off with abrasive ingredients, as most whitening tubes of toothpaste do, they can be less detrimental in the long run for people with sensitive teeth or gum recession, explains cosmetic dentist Dr. Lawrence Fung. Other pros include ease-of-use and the convenience factor, not to mention that strips are generally a very wallet-friendly whitening option. At the end of the day, strips are a great first step into the world to tooth whitening, and/or a way to touch-up or maintain the results of professional whitening treatments, Fung says.

Ahead, the best teeth whitening strips worth trying in your quest for a gleaming grin.

Best Overall: Crest 3D White Whitestrips Professional Effects

Both dentists we spoke with unanimously agree that these are the best whitening strips out there and laud them for their use of hydrogen peroxide. Most teeth whitening strips contain hydrogen peroxide, the only ingredient clinically proven to whiten teeth. It’s the same active ingredient found in professional whitening treatments, though at a much lower concentration. That does mean results will be less dramatic, generally only a few shades whiter, but the upshot is much less sensitivity if any at all. 

“These were the first on the market and remain tried-and-true, with extensive research and development behind them,” says cosmetic dentist Dr. Shahira Saad, who also likes how well they adhere to teeth. Fung agrees and points out that they’re easy to use and can help whiten teeth by up to two shades on average.

Best with Light: Crest 3D White Whitestrips with Light

This kit pairs the same efficacy of the brand’s beloved strips, but kicks it up a notch with the inclusion of an LED light. For 10 days, you wear the strips for an hour, then hold the LED-light mouthpiece against the strip for another 10 minutes, five on top and five on the bottom.

The blue light works to help the whitening gel better penetrate the tooth enamel, ultimately upping the efficacy, particularly when it comes to removing super stubborn stains. Byrdie contributor Jenna Igneri is a big fan, raving about the whitening results and pointing out that she only experienced mild sensitivity that dissipated over the 10-day period.

Best for Sensitive Teeth: Lumineux Oral Essentials Teeth Whitening Strips

For those who have super sensitive teeth and simply can’t handle chemical bleaching, and/or are seeking a natural whitening option, these strips are choice. The brand is both dentist-formulated and certified non-toxic; these particular strips rely on a totally natural trifecta of coconut oil, sage oil, and lemon peel oil and are free of, among other things, sulfates, artificial colors, and artificial flavors. They’re a fan favorite on Amazon, with reviewers raving about both the impressive whitening results and complete lack of sensitivity.

Best for Sensitive Gums: Spotlight Oral Care Dental Teeth Whitening Strips

According to Saad, one of the biggest drawbacks to whitening strips is the potential for the gel to get on your gums and cause irritation. Enter this option, which comes with a comforting, vitamin E-based gum oil you can use after each strip application to soothe gums if they are in fact feeling a little wonky. Fung is also a fan: “These are great as they contain hydrogen peroxide but leave out some of the unhealthy chemicals that may be in other strips such as BPA, sulfates, and parabens.”

Best Budget: Fairywill Pro Teeth Whitening Strips

This is an affordable option to begin with but you get even more bang for your buck because it comes with two different types of strips. There’s a set of the brand’s traditional version, meant to be used for 30 minutes daily, seven days in a row. There are also two sets of their one-hour, express whitening strips included as well, choice for popping on when you need a quick whitening boost but are short on time.

Best Flavors: Zimba Teeth Whitening Strips

An unpleasant flavor is one of the most common drawbacks to any tooth whitening strip. Enter these, which alleviate that issue and come in three yummy flavors: mint, peach, and coconut. The strips are also super grippy to avoid slipping and sliding and work gradually over the course of the two week treatment period, as confirmed by satisfied Amazon reviewers.

Best Fast-Acting: Burst Coconut Whitening Strips

These hydrogen-peroxide-infused strips are choice when you want results, fast; you only need to wear them for 10 minutes per day for seven days in order to see results. Equally as noteworthy is the wallet-friendly price tag, although the brand does recommend repeating a treatment every three months for the best effects. Still, if you want to get a brighter smile ASAP, these are a great option.

Best Hydrogen Peroxide Alternative: Sheer White Professional Teeth Whitening Strips

Those who don’t want to use hydrogen peroxide for tooth sensitivity reasons should consider these strips, which use carbamide peroxide as an alternative active ingredient. While it ultimately releases hydrogen peroxide when it comes into contact with water, a study published in the Journal of Applied Oral Science found that it was less likely to cause sensitivity during in-office tooth bleaching than hydrogen peroxide. These strips contain 20% carbamide peroxide to whiten teeth in just five days, and also earn high points with Amazon shoppers for being comfortable on both teeth and gums.

Best for On-the-Go: White Glo Bright Nights Dissolving Whitening Films

These strips tout a unique technology that ensures they gradually dissolve after you apply them. As such, they’re ideal (and meant for) quick whitening boosts on-the-go, think on your way to a big event. (Though FYI, once they do dissolve, you need to rinse your mouth before eating or drinking.)

While they do contain hydrogen peroxide, Fung points out that because they’re dissolvable, the ingredient is in contact with the teeth for a shorter period of time, which reduces the effects. Still, he does note that they’re easy to use and eco-friendly since you’re not tossing the used strip in the trash.

Because teeth whitening strips contain a lower amount of active ingredients, diligence and patience are essential for achieving the desired result, notes Saad. These aren’t a one-and-done deal; you’ll need to use them daily for the entire period of time as directed. But if you can commit to doing that, you’re golden.
