11 Teeth Whitening Kits for a Brighter Smile

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."

A smile is a universal peace offering of sorts. The single movement instantly conveys a warm, kind sentiment. No words necessary. Because of that, you could say it’s undoubtedly one of your best, most valuable assets.

Unfortunately, many of the things we enjoy regularly—coffee, tea, wine, and more—can all stain teeth over time, turning them from pearly white to varying shades of a much more unsightly yellow.

While dentists say the most effective teeth whitening treatments are in-office procedures or custom-made trays that only professionals can outfit you with, those teeth-whitening or bleaching treatments typically cost upwards of $450, says Joseph Salim, DMD, owner and founder of Sutton Place Dental Associates in NYC.

The good news: There are much cheaper at-home alternatives that, when used properly, can make your teeth one to two shades lighter (as opposed to eight shades from professional treatments), says Rob Raimondi, a dentist at One Manhattan Dental in NYC.

Though you might not get as dramatic results from at-home whitening kits, there’s another upside—they’re friendlier to those with more sensitive teeth, since the percentage of whitening agents like peroxide is generally lower.

Ready to give these whitening treatments a try? We found dentist-recommended solutions—a mixture of trays, lights, and strips—that offer the best value.

3D White Professional Effects Whitestrips

There’s a reason these strips have been so popular for so long. They’re easy to adhere, effective, and cost-efficient, says Emanuel Layliev, DDS, a dentist at the New York Center for Cosmetic Dentistry. They’re great in a pinch, since—with daily use—they can lighten your teeth up to two shades in just a few weeks.

The Diamond Teeth Whitening Kit

If you have sensitive teeth that ache with traditional whitening treatments, Bendayan suggests this FDA-approved, over-the-counter system, since the hydrogen peroxide is less concentrated. And don't worry: It’s still plenty effective, thanks to the LED light—that’s what does most of the work.

Go Pre-Filled Teeth Whitening Trays

For the ultimate convenience, these disposable teeth whitening trays come pre-loaded with the right amount of whitening gel, says Salim. For maximum results, he suggests using all 10 sets of trays within a short time frame. And pro tip: You can keep them refrigerated to increases their shelf life to about a year, he says.

Fast-Dissolving Whitening Strips

The new Fast-Dissolving Whitening Strips from Smile Direct Club are an excellent option for those who want a whiter smile without the hassle of removing messy strips, says Gary Moore, DDS, a dentist in Colorado Springs, Colorado. “The strips typically dissolve within 15 minutes, making the treatment time twice as fast as traditional strips and putting sensitive teeth under much less stress.” You can even whiten your teeth while you sleep, since they dissolve on their own.

Whitening Gel

Gel is another great option for sensitive teeth. This formula is painted on, gradually whitening teeth over time, says Seema Desai, DDS. You can control how much—or how little—you apply and how often you apply it, avoiding teeth sensitivity altogether.

Teeth Whitening Kit

This teeth whitening system comes with a super-compact light that has five LED bulbs to rapidly speed up the whitening process, says Lana Rozenberg, a cosmetic dentist in NYC. “Just apply the dental-grade whitening gel, powered by carbamide peroxide—a combination of urea and hydrogen peroxide—directly to the mouth tray and turn on the LED light,” she explains. An automated timer turns off the light every 10 minutes, so you can keep track of your treatment’s progression and ensure you only use the kit for the recommended 30 minutes at a time.

Minty Teeth Whitening Strips

Zimba whitening strips come in a variety of all-natural flavors to make the 30-minute treatment just a bit more enjoyable. The premium-grip white strips are boosted with either coconut oil or mint fragrance (you choose the flavor) for a great-tasting treatment without artificial sweeteners. “Each box comes with 28 strips—enough for the recommended 14-day treatment—making this a super affordable, easy-to-use treatment that’s also gentle enough for sensitive teeth,” says Rozenberg.

Teeth Whitening Kit With LED Light

For a 100 percent vegan teeth whitening experience, try this kit, which comes with an LED light that connects to a universally fitting teeth tray, as well as syringes with a whitening gel that uses urea peroxide to lighten teeth. “It’s easy to use,” says Huang. “You simply squeeze the gel from the syringe onto the tray and insert it into the mouth for 10 to 30 minutes. After seven days you should see noticeable results.”

Optic White ComfortFit Teeth Whitening Kit with LED Light

This drugstore buy utilizes a 9 percent hydrogen peroxide solution and an LED light to achieve the desired tooth whitening. “This ingredient, at this particular concentration, produces noticeable results without running the risk of tooth sensitivity,” says Marina Gonchar, DMD, owner of Skin to Smile.

At-Home Whitening Kit

This customizable whitening kit includes three personalized whitening gels that are sufficient for six days of use and a whitening light that’s powered by 16 dentist-office equivalent LEDs to speed up the whitening process by as much as 50 percent. As an added bonus, the formulas are crafted with natural ingredients like pomegranate, chamomile flower, aloe vera, and menthol, plus they’re cruelty-free, vegan, and gluten-free.

5 Minute Speed Whitening Gel & Comfort Fit Mouth Tray

If you need a quick whitening boost for a special event, Michelle Lee Mirza, DDS, a dentist in Fair Lawn, New Jersey, says this is a great at-home kit to try. “It is very user-friendly, and it comes with a comfortable tray that allows for full coverage of the whitening gel on your teeth, along with a rinse to combat stains in the future.” Plus, you can’t beat the value.

Teeth Whitening Kit

If you have sensitive teeth that ache with traditional whitening treatments, Bendayan suggests this FDA-approved, over-the-counter system, since the hydrogen peroxide is less concentrated. And don't worry: It’s still plenty effective, thanks to the LED light—that’s what does most of the work.
