Even if you take good care of your teeth by brushing with a good whitening toothpaste and flossing regularly, daily wear and tear might still leave your smile looking less bright. At-home teeth whitening kits can help and be a great, affordable alternative to professional whitening treatments at the dentist's office. That said, they're not all effective, and some can cause teeth sensitivity, even after just one use. Luckily, one of our favorite options, the Crest 3D Whitestrips Professional Effects Kit, is on sale now at Amazon.
Our editors on the Reviews Team have tested plenty of at-home teeth whitening kits, and Crest's easy-to-use strips and dentist-recommended effective formula made it our favorite teeth whitening kit overall. While the strips are effective at whitening teeth over the course of several uses, their gel formula contains a lower amount of hydrogen peroxide than many other teeth whiteners, making it less likely to cause tooth sensitivity. The strips comfortably adhere to teeth using Crest's "Advanced Seal Technology," so you can even drink water and go about your day while you wear them.
Each kit comes with 20 sets of strips that you wear for 30 minutes a day. As a bonus, the kit also includes two sets of Express Whitening Strips, which you can wear for one hour at a time to see visible results immediately, so they're perfect for when you have an event or are being photographed and want to have some extra dazzle in your smile. The strips are super easy to use; simply peel off the backing, stick them to your teeth, and wait. Just be sure to keep the strips off of your gums to avoid causing irritation.
With over 72,000 five-star ratings, it's clear this whitening kit is also popular among Amazon shoppers. "I've tried a few different whitening methods over the years, from pricey professional treatments to messy gels, and honestly, Crest whitening strips are my absolute favorite. They're just so convenient," said one reviewer. "I saw a noticeable difference after just a few days, and after the full course, my teeth were significantly whiter. I'm talking about a legit, noticeable brightness that gets compliments. And the best part? No sensitivity!"
Some shoppers even said the Crest strips gave them professional-level results. "I compared my results with a friend who got professional whitening. What he got was equivalent to about three to four sessions with these strips, so they're definitely worth the money," said another reviewer. "I've gotten compliments from friends and my dentist after using these. I've used gel and UV self-applications in the past, and these are way better."
With the current discount on Amazon, the Crest Whitestrips Kit is 31% off the original price. Add it to your cart now for just $30 while the deal lasts.
