The Best Teeth Whitening Kits On Amazon To Illuminate Your Smile (2024)

Customer rating: 4.5 out of 5 stars | Reviews: 6,900+ |Type: Tray |Active ingredient:Hydrogen peroxide |Usage directions:15 to 30 minutes daily

This teeth whitening kit comes with pre-filled trays that use hydrogen peroxide as the active ingredient. All you have to do is wear the tray for 30 to 60 minutes and then throw it out—no LED lights or additional steps required. The trays mold to your mouth, so the whitening gel sufficiently covers all your teeth, and it has a pleasant mint flavor so an hour of wear doesn’t feel like a lifetime.

A number of dentists selected Opalescence Go as their favorite pick when Forbes interviewed them to select the best teeth whitening kits. They praised the strength of the solution in particular. “It’s strong enough to be effective, but not too strong that it will make teeth sensitive,” said Dr. Sharon Huang, a NYC-based dentist.

What the reviews say: “I’ve had some success with whitening strips in the past, but nothing really too noticeable. This was more noticeable after one use than a whole box of whitening strips at the same price,” says a 5-star reviewer.

If you’ve ever tried to whiten your smile, you know that some of these kits can leave your teeth feeling a little sensitive. The Lumineux teeth whitening kit on Amazon is free of the peroxide that is often the cause of that sensitivity. Instead, it relies on plant-based essential oils, including sage, lemon and coconut, and comes with a four-part kit—teeth whitening strips, toothpaste, toothbrush and mouthwash—that works together to lift those stains from your once pearly whites.

What the reviews say: “This works great, even after one use,” says 5-star reviewer. “The taste is actually good. We use the the whole system and can tell a huge difference after only a month. Does not leave your teeth feeling sensitive.”

Customer rating: 4.1 out of 5 stars | Reviews: 1,900+ | Type: LED whitening tray |Active ingredient:Hydrogen peroxide |Usage directions:8 minutes four times per day for 5 days

While this kit requires a bit more of an initial commitment, both in time and money, it does aim to deliver faster results that are more akin to those achieved in the dental chair. Dentist Dr. Angelique Freking, the director of Park Slope Dentistry Seventh Avenue, recommended this teeth whitening kit to us when previously interviewed, confirming the LED and hydrogen peroxide combo works well together. Each application lasts just eight minutes, but users must be willing to repeat the process several times a day. That patience might pay off quickly, as GLO claims that you’ll see teeth that are five shades whiter in just five days.

What the reviews say: “Absolutely a must have! Amazing results and fast results that are lasting,” says a rave review. “No irritation while applying this product to teeth. Applying the tube of of gel to your teeth is pretty easy and doesn't taste bad. The results are worth every minute of your time!”

A number of our editors love these Crest teeth whitening strips available on Amazon and at many drugstores, too. They’re simple to use (just stick them on post-brushing your teeth for 30 minutes to an hour, depending on the particular model of strip you’ve bought). The main ingredient is hydrogen peroxide, which explains how these strips get to work on stains.

What the reviews say: “You cannot beat the price for what comes in this kit,” says a satisfied reviewer. “The 1-hour strips work so well if you are looking for a quick whiten. I take really good care of my teeth and they were as white as I could get them, but once I started using these, wow—I was in shock at how white they became.”

Customer rating: 4.4 out of 5 stars | Reviews: 36,200+ | Type: Gel pen |Active ingredients:Carbamide peroxide |Usage directions:30 minutes, twice a day

Whitening pens aim to leave the sometimes messy, and certainly more clunky, trays behind. Simply twist the pen and then apply the gel directly to your teeth, avoiding the gums. Hold your smile for 30 seconds to keep the whitening gel from dispersing before it has dried on a bit better. A bonus: These pens are nice and compact, making them easier to take on the go than trays.

What the reviews say: “Inexpensive and effective,” says an impressed customer. “I'm a big fan of these teeth whitening pens. They are easy to stash in my purse so I can maintain the whiteness of my teeth. The tiny brush applicator makes it really easy to get any stains between your teeth, which do not often fade when I use a full mouthguard-style bleaching [product].”

Customer rating: 4.5 out of 5 stars | Reviews: 9,700+ | Type: LED whitening tray |Active ingredients:Carbamide peroxide |Usage directions:5 to 10 minutes per day

This affordable teeth whitening kit on Amazon combines gel-filled trays with a battery-operated LED light treatment. Some reviewers suggest that the setup is a little confusing at first, but ultimately it conveniently only requires a commitment of 5 to 10 minutes of use each day. Carefully follow the instructions to avoid getting the gel on your gums; you may have results as early as one treatment in.

What the reviews say: “I've been using this on average once a day since I bought [it],” says a reviewer, who reports, “my teeth are six shades whiter since I started. Even though it took longer to whiten my teeth than I initially thought, I don't have any bad side effects of sensitivity or discomfort.”
