The Best Teeth Whitening Strips for a Brighter Smile (2025)

We all want whiter and brighter teeth, because we all have habits that put our teeth through the ringer (here's looking at you, coffee). While pro whitening treatments at a dentist's office are an option, they can be expensive. The good news is there are plenty of at-home options these days, from whitening kits with LED attachments and even on-the-go teeth whitening pens, but the tried-and-true product for at-home teeth whitening is with one of the best teeth-whitening strips.

Teeth whitening strips are thin, flexible strips coated with a peroxide gel that removes surface stains and discoloration. They're easy to use and there are a lot of options out there for you to choose from. But picking the right—and, more importantly, the most effective—one means you have to consider a few things.

Below, Walter Wang, dentist at Tend Wall Street, and Marc Lowenberg, cosmetic dentist at Lowenberg, Lituchy and Kantor in New York City, break down how teeth whitening strips work and offer their picks on the best ones you should try. We also threw in some of our favorites, so you can shop with confidence knowing each one below has been thoroughly tested and reviewed.

Made with plant-based materials that are without preservatives, additives, artificial dyes, or flavorings, these whitening strips are one of the most eco-friendly options out there. It also aims to keep your teeth microbiome-safe with its non-toxic ingredients, making it ideal for sensitive teeth and gums. Bazaar's beauty director Jenna Rosenstein used these before her wedding day with great results.

These whitening strips guarantee a noticeable difference in just a week. It also comes with custom-fit strips for comfortable wear.

Zimba offers you multiple flavors (mint, peach, coconut, etc.) to enjoy while its strips work to whiten your teeth. The strips also grip onto enamel with almost zero slippage during the process. After two-weeks, you'll notice a dramatic difference.

Can a whitening treatment be that good at a low price point? With Persmax, absolutely. Easy to apply without any discomfort and noticeable brighter teeth after a few treatments, this can't be beat.

Crest is one of the most trusted brands out there when it comes to anything teeth-related. Lowenberg says these white strips are an effective option on a budget. "The bleach within the strips remains in contact with the tooth enamel long enough to deliver noticeable results," he explains. "They contain a flex-fit Advanced Seal Technology no-slip grip which helps the strips stay put so you can talk and drink water while whitening teeth. They give an immediate boost to your smile and when you know your teeth look whiter, you’re going to naturally go around smiling."

Made with sensitive teeth and gums in mind, these whitening strips contain coconut oil to lift stains. It also boasts a no-slip grip where strips hug the teeth during treatment for comfortable wear.

These strips mix hydrogen peroxide with coconut and mint oil to remove heavy stains. It's super gentle and you'll notice a huge difference in your teeth in just a week.

The best way to whiten teeth is dependent on a person's dental health and personal preferences. Wang says that there are many options to choose from, such as professional dental treatments, over-the-counter whitening products like strips or gels. That combined with good oral hygiene of regular brushing, flossing, and dental cleanings is a solid game plan for keeping your teeth bright. But if you have any questions, he says to consult a dentist to determine what will work best with your specific needs.
