Your Spring Glow-Up Starts Here — These Teeth Whitening Strips Lightened Our Teeth Up to 16 Shades Whiter (2024)

Duration: 60 minutes︱Active ingredients: Hydrogen peroxide and sodium hydroxide︱Usage: Daily for seven days

We found the Crest 3DWhitestrips 1-Hour Express Dental Whitening Kit to be the best whitening strips for a number of reasons. For starters, they’re easy to use. The kit says not to brush your teeth prior to use (as it’s supposed to help prevent excess sensitivity), so we simply wiped our teeth dry and applied the strips so that they would adequately stick. The side meant to hug your teeth is slightly textured and gummy, which we found made them adhere easily. From a comfort stance, these strips fit easily over teeth and stay in place once on. While it’s apparent that you have a film over your teeth, we found the strips to be smooth and comfortable while wearing.

Most importantly, they’re effective and the value can’t be beaten. When we cycled through the entire kit, our teeth got six shades whiter—which was a welcome surprise in just a week. Best of all, the results are said to last upwards of six months.

One of the biggest complaints about teeth whitening strips is that they cause sensitivity. The iSmile Teeth Whitening Strips are formulated with this in mind. With mint and coconut oils at the forefront, these whitening strips are not only more pleasant to use, they’re gentler, too. To see just how well these strips live up to their claims, we tested them on someone who has long-avoided whitening strips in favor of whitening toothpastes, due to how sensitive the strips make their teeth. After wearing the strips for 30 minutes a day for seven days straight, we found that the strips adequately whitened their teeth a full eight shades—all without triggering any pain in the process.

If you’re looking for quick, dentist-approved results, we found that the Crest 3DWhitestrips Glamorous White Dental Whitening Kit works well. (It also happens to tout the American Dental Association’s Seal of Acceptance, which means that the product is safe to use, of the utmost quality, and proven effective). The teeth whitening kit comes with strips designed for the upper and lower rows of teeth, and are designed to hug each set securely. Although we didn’t find these strips to be the most comfortable to wear—simply because they trigger excess saliva production which in turn makes them slip from place if you’re not keeping your teeth clenched—we were admittedly impressed by the strips’ whitening effect.

If you’re looking for the best whitening strips that work well on the go, consider the Moon Oral Care Dissolving Whitening Strips. These fan-favorite teeth whitening strips come in the form of slim rectangles that can be comfortably folded over the top and bottom rows of teeth. The very best part about these strips is that once on, they immediately get to work and start dissolving in the process, so there’s no clean-up at the end of treatment. The only downside, though, is that while dissolving, the strips become a bit slimy, which may be uncomfortable for some (though, never painful or sensitive). While these teeth whitening strips are particularly easy to use, it’s worth mentioning that the results aren’t long-lasting. Because of this, you may want to reserve these dissolving whitening strips for special occasions like dates, parties, weddings, and other big events where you want a burst of brightness for a few hours on end.

If the idea of wearing whitening strips for an hour feels like a prison sentence, the Crest 3DWhitestrips Bright Dental Whitening Kit takes just 30 minutes to process. The kit comes with enough strips for 11 days' worth of whitening. These strips were easy to apply—but it’s important to take your time. The strips are designed to be pressed into teeth and folded over the edge. When done with care, these thin strips will stay in place, however, if done hastily, they will slide around and not be as effective. After seven days of consecutive use, we noticed that our teeth had shifted a full four shades whiter. And considering our tester is a self-proclaimed coffee addict, that’s saying something!

Not all teeth whitening strips require shelling out $30 or more. The PERSMAX Teeth Whitening Strips are an Amazon top seller, and for good reason. The textured rectangular strips are designed to fit the upper and lower teeth with ease. Said to be safe for enamel and formulated to not trigger sensitivity, we were eager to put them to the test. When we did, we found that these strips grip teeth exceptionally well, without slipping around or edging into the gumline. More remarkably, they offer instant results. When we removed these strips after 30 minutes of processing, our teeth looked a full two shades whiter.

The Rembrandt Deeply White + Peroxide 1 Week Teeth Whitening Kit promises 90 percent whiter teeth in just seven days. Thinking it was too good to be true, we put the top-rated strips to the test. In doing so—by wearing them on our top and bottom teeth for 30 minutes a day for seven days straight—we found that our teeth looked a whopping 14 shades whiter. As if the stunning results weren’t enough to make us lifelong fans, the easy application process certainly is. These strips are a bit larger than the others we’ve tried, but we found that they stick firmly to teeth to deliver stellar whitening results sans any discomfort in the process.

Formulated with coconut oil and aloe vera alongside hydrogen peroxide, the Burst Oral Care Teeth Whitening Strips are said to be some of the gentlest whitening strips on the market. During our testing, we found that the textured adhesive strips were easy to apply and stayed put once stuck on. While they lived up to their gentle claim and even brightened our teeth two shades, we found that the strips didn’t offer the most dramatic results. That said, if your goal is to gradually transform your teeth, these gentle strips might be fully in line with your wants and needs.

Last but not least, we have the Snow The Magic Strips. This kit of teeth whitening strips has earned high praise for its fast-acting brightening abilities and we were glad to see that they actually delivered. While these strips were easy to use and whitened our teeth a full six levels, though, we found that the size was a bit too small for our liking. Even on someone with smaller teeth, these strips have a hard time covering every edge, which means they may not offer the most uniform results on larger teeth.
