From coffee and tea to curry and pasta sauce, many of our favorite foods (okay,sauces) and beverages can stain our teeth yellow, making them anything but pearly whites. While someteeth whitening productscan help lift away pesky surface stains, LED whitening kits utilize the power of technology to brighten and whiten more effectively.“LED whitening kits help break down and remove stains that can buildup in between whitening treatments,”Dr. Michael Kosdontells PEOPLE. “These easy-to-use kits offer aninexpensive and effectiveway to maintain the whiteness of your smile in the comfort of your own home.”Why Buy LED?While LED whitening kits are typically more expensive compared to other at-home treatments such aswhitening stripsor pens, board-certified endodontistDr. Alexa Martinsays they can be quicker and more effective. “The light helps activate the bleaching ingredient that breaks down the pigmented molecules in your tooth, so everything works faster," she explains.With the benefits of LED teeth whitening devices on our minds, we conducted real-world testing of 27 kits to find the best options for sensitivity, stains, quick results, and more.

Only enough for six treatments (but you can buy refills)

Whether you’re shopping for convenience or a quick fix, this KeySmile is one of the fastest teeth whitening kits we’ve tried. The kit doesn’t come with a lot of formula — only three gel syringes which totals six treatments — but we experienced a noticeable difference after just one use, and you only need to use it for 10 minutes per day for less than a week to get results. With that in mind, it’s a great touch-up option you can use over time to maintain a brighter smile. After you use up all the syringes, you canbuy refillsfor around $5 per treatment.

What’s Included:1 LED light, 1 mouth tray, 3 gel syringes, 1 shade guide |Recommended Use:Use 10 minutes per day for 6 days |Active Ingredients:Phthalimidoperoxycaproic acid

Albeit a bit of a time commitment on the daily, the multiple rounds of whitening helped to brighten teethmuchfaster than other options. With regular use, we saw our teeth go from a shade 24 to a shade 8 after just one week, which makes the $95 well worth the investment. In addition to the treatment, we love that this kit comes with a whitening gel toothpaste that you use in addition to your regular toothpaste to support the kit’s brightening efforts.

ARC Blue Light Teeth Whitening Kit:We also tested the ARC Blue Light Teeth Whitening Kit, which comes with the blue light device and 14 treatments and is designed to brighten teeth in 30-minute sessions. While we experienced noticeably whiter teeth after just one use, the results weren’t that different from traditional teeth whitening strips, and the process wasn’t very comfortable and made our teeth feel a tad too sensitive.

Novashine LED Teeth Whitening Kit:We also tried the Novashine LED Teeth Whitening Kit and love that it plugs into our phones and is compatible with many different inputs. It also comes with several gel pens so you get quite a bit of formula, and although the LED light was super bright, it was still comfortable to wear (thisdefinitelywasn’t always the case while testing these kits). While testing this kit out, things started out positive, but in the end, we didn’t see significant whitening.

Our VerdictAs a continued effort to deliver high-quality recommendations, we tested eight more LED teeth whitening kits after the initial publication. Based on our new insights, we re-evaluated top picks and added new products, including theCrest 3DWhitestrips Sensitive + LED Light At-Home Teeth Whitening Kitwhich is now our best overall choice.

Our Verdict

As a continued effort to deliver high-quality recommendations, we tested eight more LED teeth whitening kits after the initial publication. Based on our new insights, we re-evaluated top picks and added new products, including theCrest 3DWhitestrips Sensitive + LED Light At-Home Teeth Whitening Kitwhich is now our best overall choice.

What to Know About LED Teeth Whitening Kits

Active Ingredients

One of the first things to consider in an LED whitening kit is the active ingredients, says Dr. Kosdon. He recommends looking for whitening formulas that feature either hydrogen peroxide, carbamide peroxide, or a combination of both. “These are the same whitening [ingredients] we use in the office and give the best results,” he explains.

All of the whitening kits on our best list feature either hydrogen peroxide or carbamide peroxide, including theCrest 3DWhitestrips Sensitive + LED Light At-Home Teeth Whitening Kit, which is our top pick for the best LED whitening kit overall, and theZimba On-The-Go Whitening Kit, our runner-up.

Sensitive Formulas

Teeth whitening can sometimes cause sensitivity in the teeth and gums. And although many at-home formulas feature more gentle ingredients and methods, some formulas might feel more irritating than others. If you are prone to tooth or gum sensitivity, Dr. Brittany Ang, DMD MDS MBS, an orthodontist atCurve Orthodonticssays to “look for a gentler formula to reduce the risk of sensitivity.” She also recommends using a whitening toothpaste formulated with potassium nitrate, which reduces sensitivity and whitens teeth.

After testing several options, we found that theByte BrightByte Prowas the best LED whitening kit for sensitivity. We also loved theMySmile Teeth Whitening Kit with LED Light, which didn’t create any discomfort while testing.

To get the best results, you’ll want to follow the whitening kits’ recommended usage. Not all LED whitening kits have the same application or time requirements, so it’s important to consider the recommended use and how that impacts your schedule, as some LED whitening kits require a longer commitment, and others take just a few minutes. For example, theCrest 3DWhitestrips 1 Hour Express + LED Lighttakes about one hour and five minutes, while theMySmile Teeth Whitening Kit with LED Lighttakes 10 minutes per day.

Smartphone Connection

Many LED lights require a power cord, which can make the whitening process a little less convenient. So, when shopping around for LED whitening kits, Dr. Martin says to look for options that connect to your smartphone for power “so you can whiten with your phone in your pocket.” This semi-cordless approach to LED teeth whitening makes whitening more accessible and allows you to multitask while brightening the teeth.

To find the best LED whitening kits, the PEOPLE Tested team put 27 kits to the test. Since each LED whitening kit requires different timelines, we followed the manufacturer’s recommended usage, so, in some cases, they tested the kits for several days, and in other cases, they used them over a several-week period. Throughout the testing period, our team considered their overall experience while also focusing on five key attributes:

Frequently Asked Questions

Our top pick for the best whitening kit is theCrest 3DWhitestrips Sensitive + LED Light At-Home Teeth Whitening Kitbecause it combines whitening strips and an LED light for a straight-forward and beginner-friendly application process.

Regarding dentist-recommended teeth whitening, Dr. Kosdon says either an LED whitening kit or whitening strips will work. “The strips require a little less work as they are ready to use out of the box, while the LED light activates the bleach in the gel, which works just like the light we have in the office.”

Typically, both LED kits and kits without LED use the same whitening agents (hydrogen peroxide or carbamide peroxide), so the biggest difference between an LED teeth whitening kit and one without is the use of the LED light.

When covering the best LED whitening kits, Jessie thoroughly reviewed the PEOPLE Tested team’s insights and carefully considered the application process, recommended use, and how well each kit worked at whitening teeth throughout the testing period. She also reached out to dental experts to learn more about the benefits of LED whitening kits and what to look for when choosing one.
