The 10 Best Teeth Whitening Strips of 2024 ...

Here are the best (and most effective) teeth whitening strips that PEOPLE tested.

With all of these benefits to consider, it’s no wonder there are dozens of teeth whitening strips on the market. Our PEOPLE Tested team tried 23 different options from Amazon, Crest, Burst, and more to find the 10 best teeth whitening strips. Throughout the process, variations of Crest Whitestrips stood out among the rest, and the only major drawback was tooth sensitivity after a few applications.

If you experience tooth or gum sensitivity, Ang says at-home whitening strips can also be worth trying as they are typically designed with more gentle formulas. “Most at-home whitening strips use a hydrogen peroxide concentration under 16 percent, whereas in-office treatments use a concentration of 25 to 40 percent,” she explains. Because of this, Ang says patients with a history of tooth or gum sensitivity might have a more comfortable experience with at-home teeth whitening strips.

“The average cost of getting your teeth professionally whitened ranged from $650 to $1,000, and professionally-dispensed kits that you get from the dentist's office average $100 to $400,” says Brittany Ang, DMD, MDS, MBS, of Curve Orthodontics. She explains that, although an in-office whitening treatment is more involved, at-home whitening strips can yield effective results.

Similar to sheet masks , these whitening strips are simple and easy to apply to the teeth — and most only require a 30-minute treatment time. Additionally, at-home teeth whitening strips are a cost-effective solution for achieving a whiter smile, as a majority of options cost less than $60 for a week’s worth of treatment.

Whether we’re sipping on a Starbucks latte, eating a bowl of pasta doused in our favorite marinara sauce, or munching on a piece of dark chocolate, our pearly whites are constantly in contact with teeth-staining foods. And, just like we might turn to at-home skin treatments for evening skin tone and erasing dark spots , we can use at-home treatments, such as teeth whitening strips or LED whitening kits , to target yellowing teeth and provide an overall brighter, whiter smile.

While the strips get a little slimy when dissolving, that is expected with dissolving whitening strips. Plus, we love how effective these are at brightening teeth and removing stains, and the treatment time is only 15 minutes, so they’re well worth a little bit of slime.

If you prefer a dissolving option, we found the best quick-dissolving teeth whitening strips are the Moon Oral Care Dissolving Whitening Strips. Formulated with gentle hydrogen peroxide, these strips are a great option for sensitive teeth and gums. They also effectively lightened teeth after just one treatment session. The super-thin feel is barely noticeable on the teeth, making them one of the more comfortable options on our list.

When they dissolve, they do feel a little slimy on the teeth.

The treatment time is only 15 minutes, which is a much shorter period than most whitening strips.

If you want ultra-effective whitening strips and can commit to a one-week treatment plan, we recommend the REMBRANDT Deeply White + Peroxide 1 Week Teeth Whitening Kit, which you can order on Amazon. This teeth whitening kit comes with 14 treatments that you use morning and night for seven days. Although the strips touch the gums and aren’t the greatest fit, they were by far one of the best options for actually whitening teeth as they lightened our pearly whites from S24 to S10. They also don’t have any of that weird foaming or sticky residue that can often come with whitening strips, and they only take one week to achieve incredible results.

They didn’t have a lot of foaming or sticky residue, which isn’t usually the case with whitening strips.

While they have a comfortable fit, we found that the bottom strips weren’t as secure as the top strips, so that’s definitely something to keep in mind if you have fit concerns. Additionally, the strips felt a bit slimy halfway through the treatment time, so if you’re sensitive to texture, we recommend trying something else, such as the Crest 3DWhitestrips Bright Dental Whitening Kit .

Dentists love the Crest 3DWhitestrips Glamorous White , and after testing them for a couple of weeks, so do we. These Crest Whitestrips are formulated with hydrogen peroxide for a gentle yet effective glow-up and take only 30 minutes to cure on the teeth — but we totally noticed a difference after just one use and without experiencing sensitivity. We love these as both an at-home whitening treatment and for maintenance, as they work effectively at reducing stain build-up. After 14 treatments, our teeth went from S10 to S8.

The strip for the bottom teeth isn’t as secure as the strip for the top teeth.

These brightened teeth after just one use, and after 14 treatments, our teeth went from S10 to S8.

For the easiest application, consider the Burst Oral Care Teeth Whitening Strips, which are a great value for 10 treatments. We love these because they are not only super convenient, but they have an excellent fit and a barely-there feeling that stays put the entire treatment time. In addition to their great value and excellent application, these whitening strips are formulated with only 6 percent hydrogen peroxide, so they’re another good option for sensitive gums and teeth (though this also means they aren’t strong enough to brighten teeth beyond a few shades). Plus, they feature nourishing and soothing aloe vera and coconut oil for added gum and teeth perks.

These are super easy and convenient to use, plus they have a great fit.

These whitening strips feature 22 treatments and are still much cheaper than in-office treatments. Plus, they fit well on the teeth and can whiten teeth by several shades without irritating gums and teeth, making them well worth the price.

If you’re looking for a less expensive way to brighten sensitive teeth, try the iSmile Teeth Whitening Strips. The PEOPLE Tested team member who tried these strips has highly sensitive teeth and usually experiences sensitivity with almost every whitening formula. However, they only noticed a few tingles here and there over the two-week testing period. And, despite their more gentle formula, the strips were still able to lighten teeth from S24 to S16, thanks to their hydrogen peroxide-based formula.

The strips are difficult to remove and the gel gets stuck to the teeth and fingers.

Even though we usually experience sensitivity when whitening teeth, we found these were most comfortable and rarely caused a tingle over the two-week testing period.

Although the application process is challenging and the strips are a tad bit uncomfortable to wear, the daily processing time is low and the results and lack of teeth sensitivity make it worth it.

While we loved the efficacy of these whitening strips, the consistency of the strips was offputting and the application was challenging. The strips are oddly shaped and we felt they didn’t provide adequate coverage for our teeth. After snipping the strips in half length-wise, however, we were able to get full coverage. They were also really wide, so we had to position them perfectly so they wouldn’t touch our gums. The paper consistency made the strips difficult to adhere correctly without tearing and we noticed our lips would stick to them, making it awkward to talk or carry on as normal during the whitening process.

If you have sensitive teeth or gums and are looking for at-home teeth whitening strips that can brighten and whiten without causing irritation (or those awful shooting pains that can occur), we recommend the Superstrips Professional Teeth Whitening Dissolving Strips. In just one week for 15 minutes per day, Superstrips promises to get teeth eight shades whiter. While we didn’t achieve those lofty results, we did notice our teeth were at least two shades whiter and noticeably brighter than when we started.

The treatment time is only 15 minutes per day — one of the shortest on our list.

Additionally, they are formulated with gentle yet effective hydrogen peroxide and although they only brighten teeth by a few shades, we saw a noticeable difference in our teeth color after just one use.

For another less expensive option, consider the Persmax Teeth Whitening Strips. These whitening strips are designed with excellent grip and a snug and comfortable fit, so you don’t have to worry about slipping and sliding during the 30-minute treatment period.

They only brightened the teeth by a few shades (though we still loved the results).

We found these were quite comfortable to wear compared to others we tested.

We saw a change in teeth brightness after the first use.

Due to the shape of our teeth, these strips were a little more noticeable compared to the express option and overlapped our gums slightly but, despite that, never caused sensitivity. We wish they were available in a mint flavor, but beyond that, they were comfortable and stayed put throughout the 30-minute treatment time.

Formulated with gentle hydrogen peroxide, these white strips are meant to be used once per day for 30 minutes. After the testing period finished, our teeth were whitened from S12 to S8. They’re easy to use, have a secure fit, and the residue doesn’t leak through the sides.

If you’re looking for another Crest whitening strip product that is a little less expensive, we were also highly impressed by the Crest 3DWhitestrips Bright Dental Whitening Kit. Unlike the Crest 3DWhitestrips 1-Hour Express , these whitening strips are designed to be used over an 11-day treatment period and can effectively whiten teeth by several shades.

We wish these had a mint flavor, which would make the taste experience more enjoyable.

These are a little more noticeable on the teeth compared to the Crest 3DWhitestrips 1-Hour Express.

These whitened our teeth up to four shades during the testing period.

Although highly effective, we would not recommend this kit for anyone with sensitive teeth. Our tester noticed issues with sensitivity after the first use and was unfortunately unable to finish the treatment plan. However, if you don’t struggle with teeth sensitivity, have an hour to spare each day, and want whiter teeth in two weeks, these strips will get the job done.

The application process was a breeze and only took about 30 seconds to get the strips situated on the top and bottom teeth. With no-slip grips, the strips stay in place for the allotted time and are super thin so they’re comfortable and barely noticeable while wearing. (You could even toss these on before your morning commute.)

If you’re looking for rapid results, look no further than the Crest 3DWhitestrips Radiant Express At-Home Teeth Whitening Kit. This kit is meant to be used for one hour a day for just two weeks to achieve professional-level whitening at home. After just one use, we noticed our teeth were two shades whiter and significantly brighter and more even in tone than before.

The thin strips stay in place on the teeth, thanks to no-slip grips, and they are comfortable to wear.

Throughout the testing period, we found that one of the most impressive aspects of these strips — especially considering the one-hour treatment time — is the tacky surface, which sticks to teeth effectively for long periods of time. We also loved the shape and size of the strips as they never touched our gums and, therefore, didn’t increase the risk of sensitivity. The strips are on the more expensive side; however, we think they’re worth the price, considering you can use them as a one-time treatment and over time for brighter, whiter teeth.

After testing 23 options, we found that the Crest 3DWhitestrips 1-Hour Express are the best at-home teeth whitening strips. These whitening strips are formulated with hydrogen peroxide and are designed as a quick solution to brighten teeth in just a single one-hour session. Upon our first test, we noticed a change in our teeth color, which was impressive for one-time use. However, we found that these Crest whitening strips were the most impressive after several uses as they effectively removed stains and made teeth whiter by six shades.

They are the most expensive option on our list (unless they're on sale).

Due to the size and shape of the strips, they don’t touch the gums.

They have a firm and tacky surface that sticks to the teeth well.

Other Teeth Whitening Strips We Tried

• DrDent Professional Teeth Whitening Strips: In addition to our top picks for the best whitening strips, we also think the $20 DrDent Professional Teeth Whitening Strips are worth considering. While these white strips weren’t as impressive as some of the others on our list, we still think this is an excellent at-home whitening option for those shopping for cheap whitening strips on Amazon. They provide decent stain removal — our teeth were two shades lighter after seven days of treatment — and don’t cause sensitivity, so they’re a good option for those with light stains or sensitive teeth. 
• Made by Dentists Express Teeth Whitening Strips: The $50 Made by Dentists Express Teeth Whitening Strips are another option worth mentioning due to how easy they are to apply to the teeth and how comfortable they are on sensitive teeth and gums. While they don’t boast outstanding whitening results, we think that they are a good option for maintenance as they help lift away light staining. 
• Snow The Magic Strips: If you’re concerned about gum sensitivity, the $26 Snow The Magic Strips are another one of our honorable mentions worth considering. While we found that these strips were a little small and didn’t love how they dissolved on the teeth, we found that these were still effective at brightening by a few shades and never once made sensitive teeth or gums feel uncomfortable. Additionally, these whitening strips are one of the best-tasting option on our list with a lavender mint flavor. 
• Zimba Teeth Whitening Strips: If the taste and consistency of teeth whitening strips are off putting to you, then these $24 flavored vegan strips from Zimba might be worth a shot. You can choose from six different flavors, including mint, coconut, and watermelon. Although we found the application process easy and the flavors appealing, the strips were slightly uncomfortable and didn’t feel like a natural fit on our teeth. Plus, we only noticed our teeth got a shade or two whiter after two weeks of consistent wear.

Things to Consider Before Buying Whitening Strips

Ingredients 

To find the most effective teeth whitening strips, Ang says to consider the formula and look for ingredients such as hydrogen peroxide and carbamide peroxide. “These are the two most common whitening agents used in both professional and at-home treatments since they have been proven clinically effective at whitening teeth,” she tells PEOPLE.

With this in mind, all our top picks — including our best overall pick, the Crest 3DWhitestrips 1-Hour Express — are formulated with hydrogen peroxide for an effective at-home teeth whitening solution. 

Concentration 

In addition to ingredients, Ang says to look at the concentration of active whitening ingredients (such as hydrogen peroxide) as a higher concentration equates to faster results. “Most over-the-counter treatments will have a concentration under 16 percent peroxide,” she explains. For fast-acting teeth whitening strips, consider the Crest 3DWhitestrips 1-Hour Express, which is formulated with 10 percent hydrogen peroxide to remove stains in a single one-hour session with results lasting up to six months. 

With that said, Ang says don’t discount lower concentrations entirely, as higher concentrations come with a greater chance of tooth or gum sensitivity. So, if you have a more sensitive mouth or are concerned about sensitivity caused by teeth whitening, look for lower-concentration formulas (just know that these might take a little longer to reach full effect). Although it wasn’t one of the most effective teeth whitening strips we tried, the Made by Dentists Express Teeth Whitening Strips (which include 1 percent hydrogen peroxide) are safe for sensitive teeth and worth considering if you have sensitivity. They can provide some whitening effects over time and also won’t irritate the gums or teeth.

How Does pap strips teeth whitening Work?

Since teeth whitening strips are supposed to be convenient, it’s also worth looking at the treatment commitment and how long it takes to see results. In most cases, whitening strips take anywhere from 15 to 30 minutes, twice daily, over one or two weeks. However, quicker solutions, such as the Crest 3DWhitestrips 1-Hour Express, provide a whitening effect in a single one-hour session. According to Michael Kosdon, DDS, a cosmetic dentist, the time frame doesn’t mean a formula is better or worse instead, it’s about choosing a product that fits into your preferred time frame for results. 

How We Tested

To find the best teeth whitening strips, our PEOPLE Tested team researched dozens of options before narrowing it down to 23 top picks. From there, we conducted real-world testing based on the strips’ individual treatment times and instructions to better understand how each formula works at lifting stains and brightening teeth. 

Throughout the testing period, we carefully considered the ease of use, effectiveness, and value while also making note of comfort to find options that work well and are comfortable on sensitive gums and teeth. Additionally, we examined the treatment requirements, including individual times and overall treatment length, to determine convenience and effectiveness. 

After testing the whitening strips based on their individual treatment requirements, we compiled all of our notes together and thoroughly reviewed our experiences. We compared treatment time requirements, convenience, and how effective each formula was at removing stains and whitening teeth. Plus, we noted the overall price and value for each treatment to determine which whitening strips were worth it. 

After much deliberation, we narrowed down our top picks to the 10 best whitening strips, plus a few additional honorable mentions worth considering. 

Frequently Asked Questions

• What are the best whitening strips for fast results?

  Our top pick for the best whitening strips for fast results is the Crest 3DWhitestrips 1-Hour Express. These teeth whitening strips are designed for single-use sessions and can whiten teeth effectively in just one hour, with results lasting for up to six months. For something a little less expensive, we also loved the Persmax Teeth Whitening Kit, which were comfortable to wear and improved our teeth's appearance immediately.

• Do white strips work on yellow teeth?

  According to Kosdon, teeth whitening strips work best on teeth with yellow staining caused by foods, coffee, and aging, as they can lift away the stains over time and restore your natural tooth color. With that said, if your natural tooth color is slightly yellow and you want to make them brighter, Kosdon says whitening strips aren’t effective as they won’t whiten teeth beyond the color they grew in. 

  
  

  If you’re unsure about whether or not whitening strips can transform your teeth color, Ang recommends consulting with a dentist to find out what kind of staining (if any) you might have and if white strips are the best solution.

• What happens if you leave whitening strips on longer than 30 minutes?

  Just like with other whitening products, when whitening teeth at home with strips, always follow the recommended treatment time. “If whitening strips are left on the teeth longer than the recommended time, this can lead to potential side effects including gum irritation, tooth sensitivity, uneven whitening results, and even potential gastrointestinal upset due to ingesting the active ingredients,” says Ang. Additionally, overuse or extended use beyond what is recommended can damage the tooth's outer layer (a.k.a. the enamel). 

  
  

  If you experience any of these side effects or a negative reaction to whitening strips, Ang says it’s advised to discontinue use and discuss concerns with your dentist.

• Do I rinse after whitening strips?

  Rinsing after whitening strips is recommended to remove any excess whitening gel on the teeth. “This could help prevent the excess gel from migrating to the gums and causing irritation,” Ang notes.

• Do I brush my teeth after whitening strips?

  You can definitely brush your teeth after whitening strips to remove the residual whitening gel from the teeth. However, Ang says to keep in mind that active gels can cause damage to the tooth if brushing is aggressive or a hard-bristle toothbrush is used. “Use a soft or even extra-soft bristle toothbrush and be cognizant to gently brush all surfaces to prevent damage to the teeth and gums,” she explains. “Brushing gently and with a soft-bristle toothbrush will not interfere or affect whitening unless the manufacturer specifically instructs not to brush after the use of the strips.

As seen on Allure, Dr. Hadaegh recommends one of his favorite drugstore teeth-whitening kits.

In an ideal world, brushing your teeth routinely would be enough to keep your set of pearly whites, well, pearly and white between routine dentist appointments. But alas, for many of us (particularly those of us with a serious coffee habit), that’s just not the case. We feel moved to hit up the local drugstore for whitening products to freshen up our smiles — perhaps without giving much thought to what those products actually are and how they work.

“Tooth enamel [is] a crystal,” Matthew Messina, DDS, spokesperson for the American Dental Association (ADA), says. “If you were to look at tooth enamel under a really powerful microscope, [the structure] kind of looks like chicken wire” (or wire mesh). He explains that removing stains within the matrix of the tooth enamel is like getting out dirt stuck in chicken wire: “So what happens in whitening is we want to…open the matrix and bubble out that color, the stain, and then close it back up.”
That’s where peroxide comes in. Dr. Messina says peroxide causes that bubbling to occur, so the active ingredient in whitening kits you buy will be hydrogen peroxide or carbamide peroxide (a diluted version of hydrogen peroxide). “Carbamide peroxide is used because it’s a comparatively stable compound,” Neil Hadaegh, DDS, a cosmetic and restorative dentist in Beverly Hills, California says. “This helps the manufacturer to insure product quality and consistency at the consumer’s end.” Dr. Messina notes that aside from the peroxide, over-the-counter whitening products usually contain some additional ingredient to improve the taste.

Peroxide is the main active ingredient in the products dentists use to do professional whitening in their offices, too. The only difference is the concentration. “If we’re doing something where we can mask off the gum tissue…where the gum tissues are protected, we can use a stronger whitening agent…because it’s only touching the teeth,” Dr. Messina says. “Something you’re using over-the-counter has the potential to touch the gum tissues or be swallowed. So, we have to use a much lower strength of the active ingredient because…it might burn [the patient’s] gum tissues.” Professionals, on the other hand, “can take all the necessary precautions to make sure the gum tissue is safe and protected and the whitening agent is only getting on the tooth enamel that we want whiter.”

Ultimately, Dr. Messina says that all over-the-counter, peroxide-based whiteners will deliver comparable results as long as you follow the manufacturer’s instructions for use. One ingredient to steer clear of? Hydrated silica. Dr. Hadaegh says that the substance is “made from a crystallized compound found in quartz and sand [and] can damage tooth enamel and gum tissue.” Aside from that, Giri Palani, DDS, a dentist in Beverly Hills and Palos Verdes, California says the most important thing is to look for when you’re shopping is ease of use. “Also, [you] want to make sure that the product you buy has a good shelf life and you store the product properly ([in] the refrigerator will last longer),” he says.

Once you have a kit, Dr. Messina says you can use it for seven to 10 days to start, and then once every other week or so for maintenance. Before you do so, though, consider taking a trip to the dentist for your standard teeth cleaning and to consult on your at-home whitening plans. “Tooth whitening is something that should only be done in a healthy mouth situation,” he says. “If somebody has cavities or periodontal disease, or some other reason why their teeth aren’t white, whitening is not the right choice for them. That’s why it’s always good to have a thorough examination done by your dentist before starting on a whitening program.” Not to mention, if you do the whitening right after having your teeth cleaned at the dentist, Dr. Messina says, you’ll be whitening your tooth enamel itself rather than the tartar or build-up on top of it. Regardless, he says, involving your dentist in the discussion will help you ensure you’re taking the right path.

Once you have that conversation, consider one of these over-the-counter kits.

1. Crest 3D White Whitestrips Professional Effects Teeth Whitening Kit, $44.99 (target.com)

There’s no doubt that Crest Whitestrips are one of the most recognizable over-the-counter teeth whitening systems available. It seems almost as if they’ve been around forever — and professionals still love ‘em. “Over the counter, I recommend Crest 3D White Whitestrips,” Dr. Hadaegh says. “A lot of my patients who naturally have whiter teeth or slightly discolored teeth are happy with the results.”

Dr. Palani is also a big advocate of whitening strips. “I have had great results with the strips,” he says. “When people use strips properly, they can get very close to professional whitening.”

2. Plus White 5 Minute Dental Whitening Kit, $11.49 (riteaid.com)

When it comes to tray options, Lana Rozenberg, DDS, a New-York-City-based cosmetic dentist, likes Plus White’s 5 Minute system. They cause “very little [tooth] sensitivity, [and they’re] less expensive than the strips but a bit easier, due to the trays,” she says.

3. Dr. Collins All White 22% Bleaching System, $20.49 (target.com)

“The strips or the trays are more effective than the pens because of the prolonged contact of the gel to the tooth,” Dr. Rozenberg says. But, Dr. Rozenberg notes, over-the-counter trays are one-size-fits-all, and the looser ones could allow more gel to seep out. A custom-fit, take-home tray from your dentist is the most ideal scenario, but you can get these “boil-n-bite” trays, which you can (at least somewhat) mold to your teeth, from drugstores. Just be sure to follow all instructions, and let the tray cool enough that you don’t burn yourself when putting it in your mouth!

4. Walgreens Extreme Whitening Wraps, $14.99 (walgreens.com)

Dr. Messina agrees that prolonged contact of whitener with teeth is key. “What we have to do is keep the whitening agent on the teeth,” he says. “So strips or trays have a better ability to keep the whitening agent against the teeth [than other products like pens] because [the whitening agent is] only effective as long as it stays there and saliva doesn’t wash [it] off.” If you’re having trouble finding trays that fit your mouth well, these more fitted wraps from Walgreens could do the trick.

5. Hager Pharma Mirawhite Oxygen Tooth Whitening Pen, $31.99 (cvs.com)
That’s not to say you can’t use whitening pens; they just may be more difficult to use effectively. “That’s the challenge with something like a pen,” Dr. Messina says. “Can you keep the teeth isolated? Can you keep your mouth open long enough and your lips away from the teeth long enough for it to work? And if you can do that, they’re very effective.”

6. CVS Platinum Whitening Kit,

Dr. Rozenberg says that over-the-counter whitening kits should contain from 10 to 35 percent carbamide peroxide (or three to 10 percent hydrogen peroxide) and are most effective at higher concentrations. (Dr. Messina notes that in general, though, manufacturers adjust the concentration based on how the product will be used and how long it will be held against the teeth.) At 25 percent carbamide peroxide, this CVS brand whitening kit hits near the top of the allowable range. Just be sure you use it carefully. “The product with higher concentrations of peroxide [means] higher chances of causing tooth sensitivity if worn for an extended period of time, and may cause gum irritations as well,” Dr. Rozenberg advises. “Do not wear longer than written in the instructions.” There you have it — happy whitening!
