Testers gave the whitening strips featured in Crest's 3DWhitestrips 1-Hour Express Dental Whitening Kit top marks for their ease of use, convenience, and overall effectiveness. After cycling through the entire kit over a week, testers noticed that their teeth became six shades whiter ' an unbelievable feat. With results expected to last upwards of six months, there was no doubt that this kit deserved the top spot on this list.

Even those who take pride in low-maintenance beauty and hygiene routines will find these whitening strips fit seamlessly into their agenda ' that's how easy the whitening strips are to use. Crest mentions that you should not brush your teeth before use to prevent excess sensitivity, so testers simply wiped their teeth dry while testing and applied the strips so that they would adequately stick. The side meant to hug your teeth is slightly textured and gummy, helping them adhere easily. They'll actually stay in place once they're on, so you won't have to worry about fiddling with them to ensure you get the best results. Plus, while it's apparent that you have a film over your teeth after the strips are applied, testers found them exceptionally smooth and comfortable.

Shape's testers love keeping their teeth extra white and shiny but hate the sensitivity of most at-home (and even in-office) products. This easy-to-use set from a tried-and-true toothpaste brand features a teeth-whitening pen and LED light that give you visibly whiter teeth with less mess. Simply paint on the serum, pop it in the mouthpiece, wait 10 minutes, and go. Repeat over ten consecutive days and voilà, whiter teeth

Why It's a Shape Beauty Award Winner: Move aside whitening strips. This whitening pen is easy to use (and incredibly effective). It erased coffee stains from our testers' not-so-pearly whites. Plus, with the -powered LED mouthpiece, this set is incredibly cost-effective.

  • Messy removal process

One of the biggest complaints about teeth whitening strips is that they cause sensitivity. iSmile considered this when formulating its Teeth Whitening Strips, utilizing mint and coconut oil (which specifically aids with reducing sensitivities) to create a gentler alternative to classic whitening strips. Plus, the mint helped them not "taste as gross as other strips," as one tester mentions in her review. This same tester thankfully notes that she "didn't experience any sensitivity" after each 30-minute period, proving iSmile's claims to be valid (with those ingredients, Shape never doubted them!).

What's more? The iSmile Teeth Whitening Strips make the process easy, so there's really no excuse not to engage in this process if you're seeking whiter teeth. The tester notes how "straightforward" and "easy to apply" these strips were during the trial period and how they "stayed in place during the wear time," especially after drying her teeth beforehand. These strips were "convenient to use" in the tester's view "because they required just 30 minutes out of [her] day." She says: "I can use them while I'm working [or] walking the dog, [and] I even brought them with me on a two-week trip [because] the package was small enough to throw in my carry-on." After the testing period, this tester was pleased to notice her teeth were a shade lighter, proving that just a small, half-hour commitment each day can actually yield results.

When one Shape tester finds the Zimba Teeth Whitening Strips so comfortable that she "completely forgot that she was wearing them," you know you've discovered an exceptional product. These remain "in place throughout the full 30 minutes of treatment" and prove "very easy to take off," says this tester, overall calling them "very easy to incorporate them into your routine." Plus, they're effective! This same tester claims that these strips "definitely whitened [her] teeth, especially along the gums," where she "noticed get the most yellow [...] I honestly saw results after just one treatment." However, she notes there wasn't a "noticeable difference in subsequent treatments," so keep this in mind if you're seeking something that may be more effective in the long term. Overall, the results gave this tester a "huge confidence boost."

Shape editors love the variety of flavors Zimba offers, which helps this product stand out amongst other teeth whitening strips on the market. Opt for a classic mint or spearmint flavor, or try something new like peach or cherry.

  • Lips can stick to your teeth before strips completely resolve

If you're looking for the best whitening strips that work well on the go, consider Moon Oral Care Dissolving Whitening Strips. These fan-favorite teeth whitening strips boast a slim rectangle shape that can be comfortably folded over the top and bottom rows of teeth. Once they're secure on your teeth, they immediately start working to whiten them and dissolve simultaneously, meaning no cleanup is necessary after the 15-minute period. One tester called these strips "more comfortable than the average plastic film" and loved how they "stayed in place the whole time." Plus, these strips have the results to prove the product is not all innovative packaging. This same tester "felt a difference right away [and] was surprised that these actually gave a pretty even whitening and brightening effect." She states: "I think [the strips] gave me a more even whitening than other strips I've used."

The only downside is that the strips become a bit slimy while dissolving, though they're thankfully never painful or sensitive. After the 15-minute whitening period, the tester mentions that these still leave behind "a thick gel on your teeth" that she would have to "brush off." However, they're still "more discreet" than other whitening strips.

If wearing whitening strips for an hour feels miserable to you, The Crest 3DWhitestrips Bright Dental Whitening Kit takes just 30 minutes to process, making it the perfect option to add to your dental hygiene routine. The kit comes with enough strips for 11 days' worth of whitening, yet after only seven days of use, Shape testers noticed their teeth had become a full four shades whiter, even for one tester who can't go a day without sipping a ton of coffee ' a factor believed to cause tooth staining.

While these strips were easy to apply, testers found it crucial to take their time. The strips are designed to be pressed into teeth and folded over the edge; when applied carefully, these thin strips will stay in place, but if done hastily, they will slide around and be less effective.

Not all teeth whitening strips require spending $30 or more, which explains why the PERSMAX Teeth Whitening Strips are such a hit for Amazon users (they're a top seller and under $15). This kit comes with 28 textured rectangular strips designed to fit the upper and lower sets of teeth with ease, and the brand boasts an enamel-safe formula for those worried about sensitive teeth.

While trying these out, Shape testers found that these strips gripped teeth exceptionally well without slipping around or edging into the gum line. 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 seven days. Thinking it was too good to be true, Shape testers put the top-rated strips to the test by wearing them on their top and bottom teeth for 30 minutes a day for seven days straight, as the brand prescribes. The result? Testers found that their teeth looked a whopping 14 shades whiter. As if the stunning results weren't enough to make the Shape team lifelong fans, the easy application process sealed the deal for testers. 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 without discomfort.

The Lumineux Teeth Whitening Strips may be best known for what's not in them. They are certified nontoxic and have no harsh bleaches, artificial dyes, alcohol, or sodium lauryl sulfate (SLS). Instead, they rely on coconut oil, sage oil, lemon peel, and Dead Sea salt as a more natural approach to teeth whitening. Plus, they're effective despite the ingredients list that strays from the norm. One tester thankfully experienced "no sensitivity or discomfort" and "noticed a change [in color] within three days," her teeth turning "a uniform white."

Shape's only qualm with this product? The results don't last long. This same tester notes that after three days of brand-new pearly whites, her progress "plateaued." She states: "After that, I didn't notice a huge difference, but they were [still] effective" and "not spotty at all." Also, keep in mind that "there's a lot of whitening treatment on each strip," as this tester notes, making it a little "clumpy." "I learned you had to hold your breath so as not to fog up or add any moisture to the strip so it could stay on when applying," she notes, adding: "After about five minutes, they stayed on with no issue."

Supersmile Superstrips are worth a try if you want professional-looking brightness without the in-office appointment and price tag. They'll run you much more than other at-home kits, but they work quickly and have been shown to whiten teeth by an average of up to eight shades in seven days. Supersmile Superstrips also include Calprox, a clear bleaching agent (calcium peroxide) that targets a protein on your teeth that stains and bacteria often stick to. Thanks to this ingredient, you may benefit from preventing plaque buildup.

Testers liked that these strips dissolve, so you can just put them on and go about your day without the need to rinse. Overall, they were easy to use, and the whitening results were impressive, making this kit worth the splurge for anyone who wants to go all in with their teeth whitening routine. Remember that you have to wait at least 30 minutes before eating or drinking after using these, so be sure not to schedule your regimen before a meal.

If you're not interested in whitening your teeth as part of your regular dental hygiene routine but want some extra brightness before a special occasion (think: weddings, birthdays, photo shoots, etc.), consider Crest's 3DWhitestrips Radiant Express At-home Teeth Whitening Kit. While Shape's testers found these whitening strips to stay on during the whitening period and to demonstrate their effectiveness after around the fourth strip, the hour-long whitening session is not ideal. One tester notes: "While the actual application process is simple, I found the habit of applying and wearing the strips difficult to maintain daily due to the 60 minutes needed to wear them. I would find myself remembering to put them on but had trouble finding an hour window to wear them." For anyone enduring a busy schedule, these strips may not cut it. With this in mind, Shape recommends these for anyone wanting quick results before a big event, where they're likely already setting aside time for beauty maintenance. Testers agree, calling this kit better for instances where they "have a goal in mind for whiter teeth."

20CP Glamorous Whitening Strips - MySmile

I had been meaning to try out the Crest 5D whitestrips for a long while, and about a month ago I finally did. I use to use the Dile a Smile Whitening Kit (for about 6 months) and after the 5-5rd use, my teeth wouldn't get any whiter. Their product I got for about $60-70? And was not pleased. So I decided to try out the strips and I love them! People have really noticed my white smile and have gotten a lot of compliments on it. I can finally wear bright colors on my lips and they still look amazingly white. The first time I used the strips, it hurt and it was my fault. The instructions said not to brush your teeth beforehand and please DO NOT. I brushed my teeth and applied the strips and it burned and made my gums feel sensitive but within that one time I did noticed a difference. I'm down to my last 8-10 strips and now I only use one once a week. At first,I used 6-7 in a row. I love them, and will repurchase. Probably the one with 50 strips. Enjoy your lovely smile and have a wonderful day!!!! :)))

I have used white strips a long time ago (>10 years) and they did a great job whitening my teeth. So when I thought to try it again I was hoping for better results since I figured they would have improved the product. Well I did the 15 day treatment and it did whiten it a bit but not as much as I was anticipating so I am a little disappointed. But I give it 5 stars because it did increase the whiteness somewhat.One thing I did notice is that these do stick to your teeth alot better than before and they do not slip off. So you are able to talking regularly without sounds like you have something in your mouth.Also, as others have said it does make your teeth pretty sensitive but if you avoid extreme temperature changes in your mouth (i.e ice water) it isn't too bad.

I have used crest strips on and off for years with pretty good results. I hesitated to buy the professional effects because of all the reviews reporting tooth pain/sensitivity. I have never had a problem with sensitivity so decided to give it a shot thinking the worst that could happen is it would hurt my teeth a little but if it did I could always take an advil or discontinue use. I am on day 11 and am not seeing noticeable results. For me, the strips do not adhere to my teeth as tightly as I had expected based on the product description, therefore they are not at all difficult to remove. I have not experienced any pain or sensitivity but on the other hand, I have also not seen a lot of whitening. It has been 2 years since I last whitened my teeth and I do drink coffee everyday but the box says that it removes 15 years, or something similar, of stains. I agree with another reviewer on here that the old crest strips that were cheaper and used twice a day were much more effective at whitening teeth. One more thing, with the older brand of crest strips, I used to have a lot of gel remaining on my teeth that would need brushed off after but none at all with these new strips which makes me wonder... I have 9 more days of strips so maybe there will be a miraculous whitening at like day 19 or something, if that happens, i will definitely let you know.
