'Literally magic': Amazon's wildly popular teeth whitening kit brightens your smile — and it's only $26

In a perfect world, brushing alone would get you the megawatt smile of your dreams. Unfortunately, it usually requires a bit more work, like professional whitening treatments in addition to brushing, flossing, and twice-yearly checkups. While in-office sessions can be effective, they’re also wildly expensive — many can cost hundreds of dollars for one treatment alone. If you don’t want to fork over that much dough (and who does?) for a bright white smile, opt for an at-home alternative. Amazon shoppers think they’ve found the best one with the iSmile Teeth Whitening Kit — it's now just $26 (down from $40).

The popular kit has quite the fan base — nearly 18,000 perfect five-star reviews!

The iSmile LED Light Activated Teeth Whitening Kit is designed to brighten your teeth up to eight shades in just seven days. It’s simple: All you have to do is inject the powerful formula into the included mouth tray, and leave it on for 10 minutes a day. Boom, white teeth! “This thing is literally magic,” one shopper declared. “My teeth are whiter after just two days of applying!”

The formula is potent but gentle, packed with 35 percent carbamide peroxide that removes coffee and wine stains with ease while being safe on enamel. The kit includes three mint-flavored gel syringes, enough for multiple treatments, while the tray is powered with five LED lights, which are designed to accelerate the formula’s whitening power. It even has a built-in 10-minute timer, so you can keep track of your treatments.

One skeptic wrote: “Soooo happy I bought this! I noticed a slight improvement after just one use. On day three now and I can tell that I have gone about four shades whiter. I drink a lot of coffee (and I do mean a lot) so I definitely had the staining going on here. Now I can still enjoy my cup of joe with confidence.”

Another shopper’s husband couldn’t believe his eyes. “Holy moly guacamole!” they exclaimed. “I have used this one time. One time and my husband actually noticed that my teeth were whiter. Lol. That alone should speak volumes.”

“I was skeptical this would even work,” another reviewer shared. "I’ve bought teeth whiteners before and they didn't work. I’ve spent hundreds of dollars at my dentist for Zoom whitening, but I took a chance on this kit because my teeth were getting really yellow. First treatment I was amazed at how well it worked. I’m now on my fourth treatment and I’m happy with the results."

It's never been easier to remove stains from wine, coffee, soda and smoking.
