What is the strongest at home teeth whitening?

We independently research, test, review, and recommend the best products. Healthcare professionals review articles for medical accuracy. Learn more about our process. If you buy something through our links, we may earn a commission.

As luck would have it, many of the most enjoyable things in life can stain your teeth. Your morning cup of coffee, that evening glass of red wine, heck, even seemingly innocuous things such as tomato sauce and blueberries can leave your teeth looking dingy. As far as whitening your smile goes, at-home whitening products can provide pretty powerful results with the added bonus of being cost-effective, convenient, and causing little-to-no tooth sensitivity. Plus, versatility is the name of the game, with plenty of formats to choose from—toothpaste, strips, pens, and more—to fit any preference.

However, not all whitening products are created equal (some even freshen your breath!), so we tried some top-rated options to see if they’re really worth the hype. Our testers used these products for weeks at a time, rating how effectively and quickly each one brightened their smile (and noting whether or not they left teeth and gums sensitive or irritated). Our team then combined these results with our own research of other best-selling products and tapped cosmetic dentist Dr. Jon Marashi for his recommendations to compile this list.

Try these best teeth whitening products and get ready to flash your pearly whites.

What We Like

• Visible results in 10 days

• Easy to use

• Results last up to 36 months

What We Don't Like

• Causes mild sensitivity

Crest is no stranger to the at-home whitening world, but this latest innovation really is a game-changer. It takes the same beloved strips the brand is best known for and amps up their effects with blue light technology to provide unmatched results that can last up to 36 months.

For 10 days, you wear the strips for an hour, then hold up the light device to the strips for another 10 minutes (five minutes each on the top and bottom). The light boasts the same technology found in dentist’s offices, which helps the hydrogen peroxide in the strips better penetrate the tooth enamel and ultimately leads to whiter teeth. 

And, yes, it really works. Byrdie product tester Jenna Igneri notes she began to see a brightening effect by day five, and by day 10, her smile was noticeably a few shades lighter, while any bothersome stains had faded significantly.

Type: Strips, light | Session Duration: 70 minutes | Active Ingredients: Hydrogen peroxide, sodium hydroxide

What We Like

• Visible results in two weeks

• Easy to use

• Affordable

What We Don't Like

• Causes mild sensitivity

Truly a classic, you really can’t go wrong with these easy-to-use strips. They have the American Dental Association's (ADA) seal of approval, which was granted to them in 2017. To drive home how major that is, it's worth mentioning that it's the first product to earn the ADA seal in the Home-Use Tooth Bleaching Products category, according to the ADA. They promise to remove up to 10 years' worth of stains, and this variety features extra grip to ensure they stay in place.

Dr. Marashi is also a fan, lauding both the affordable price and the good results they deliver. Still, he does note that compliance with any at-home product is usually the main issue, so you’ll need to use these every day (for the entire duration of the two-week treatment cycle) to see the best results.

Type: Strips | Session Duration: 30 minutes | Active Ingredients: Hydrogen peroxide, sodium hydroxide

What We Like

• Portable and easy to travel with

• Visible results in five days

• Easy to use

What We Don't Like

• Remote battery runs out quickly

A little bit on the pricier side, this is pretty much the closest you can get to a pro-style treatment at home. You start by applying the protective lip balm, then brush a thin layer of the whitening gel along the fronts of your teeth. Pop in the mouthpiece and turn it on, either manually or via the app, fancy.

The GLO technology—which stands for Guided Light Optics. FYI—it uses a combo of both light and heat to activate the hydrogen peroxide-based gel, so you get whiter teeth, fast. It shuts off after eight minutes, though you have to repeat the process twice more after that. Do three cycles total for seven days in a row for impressive results.

Type: Gel, light | Session Duration: 8 minutes | Active Ingredients: Hydrogen peroxide, sodium hydroxide, potassium nitrate, sodium fluoride

What Our Testers Say

"I’d say my teeth are about one to one-and-a-half shades lighter than they were in the beginning and with consistent use past the 10-day mark, they will get even brighter." — Ashley Rebecca, Product Tester

What We Like

• Effectively breaks down dark stains

• Safe for sensitive teeth

• Safe for dental work like braces/crowns

What We Don't Like

• Expensive

This is Dr. Marashi’s pick for a full-on system. “It combines a special wavelength of light delivered via the mouthpiece combined with the whitening gel. The light activates the gel to effectively break down dark colors that are staining your teeth,” he explains. It’s a fan-favorite on Amazon, too, repeatedly pulling in positive reviews with customers commenting on how well it works and how it’s worth the price.

Each kit comes with three wands of Snow's whitening gel as well as an extra-strength version in addition to the LED mouthpiece. The best part? It's safe for use by those with sensitive teeth, braces, bridges, caps, crowns, and veneers.

Type: Gel, light | Session Duration: 9 to 30 minutes | Active Ingredients: Hydrogen peroxide, carbamide peroxide, potassium nitrate

What Our Testers Say

“If you want whiter teeth without the pain, spring for the Snow Teeth Whitening Kit With LED Light. You’ll end up with a brighter smile without the potential painful side effects and a bad aftertaste.” — Leigh Weingus, Product Tester

What We Like

• Stronger than traditional whitening toothpastes

• Affordable

• Protects with fluoride while refreshing breath

What We Don't Like

• Not as effective as strips or gels

Surprise, Crest does it again. Using toothpaste is probably the easiest way to work a whitening product into your routine—after all, you’re already brushing your teeth every day as it is. While we’ll admit, whitening toothpastes usually aren’t nearly as powerful as gels and other treatments, this one is actually a pretty solid option.

Combining the brand’s Fastest Whitening Technology and Advanced Stain Protection, it buffs off surface stains—up to an impressive 95% of them in just three days—and offers protection against further stains, all while strengthening your teeth and fighting off cavities with fluoride. We’re sold.

Type: Toothpaste | Session Duration: 2 minutes | Active Ingredients: Fluoride

What We Like

• Uses natural ingredients and extracts

• Formula foams nicely

• Freshens breath

What We Don't Like

• Fluoride free; won't protect against cavities/decay

Another game-changing whitening toothpaste is this charcoal version from the oral care brand Moon. Formulated without fluoride, it cleans and freshens the breath while its proprietary ELIXIR X blend of extracts and ingredients gets to work to whiten, brighten, and promote overall healthier-looking teeth and gums. Plus, we love that its key ingredient list sounds more like a skincare product than a toothpaste: It contains a combination of green and black teas, ginseng, echinacea, camu camu, cranberry, dead sea salt, tea tree oil, coconut oil, and peppermint oil.

It certainly doesn't hurt that it's also sulfate-free, cruelty-free, vegan. And, fine, we know this isn’t necessarily an important feature of a tooth whitening product, but the packaging is also super pretty.

Type: Toothpaste | Session Duration: 2 minutes | Active Ingredients: Activated charcoal

What Our Editors Say

“I never believed a toothpaste could whiten noticeably, but I swear my teeth look so much whiter and brighter since I started using this. Plus, I like that it's made with gentle ingredients, and the mint flavor isn't so extreme." — Faith Xue, Former Editorial Director

What We Like

• Targets pesky stains between teeth

• Made from recycled plastic

• Sustainable packaging

What We Don't Like

• Needs to be manually cut

Breaking news: It’s not just the stains on the front of your teeth that can make them appear discolored. Staining in between the teeth also contributes to an overall dingy appearance. Flossing is super important in preventing this, but you can up the ante even further by using this floss, which is infused with hydrogen peroxide.

FYI, you get just the roll of floss (without the plastic holder that you typically get) so figuring out how to pull it out and cut it takes a little bit of getting used to, but it’s well worth the extra effort.

Type: Floss | Active Ingredients: Hydrogen peroxide

What We Like

• Non-sensitizing formula

• Visible results in one week

• Promises to leave teeth seven shades whiter

What We Don't Like

• Results are subtle

Looking to whiten and brighten your smile, but worried your teeth are too sensitive for a tooth whitening product? Fear not, this teeth whitening system is formulated with a non-sensitizing hydrogen peroxide gel that won’t hurt your teeth or gums but still works super effectively. In fact, some results are noticeable in as little as one day.

Commit to using these for just one week to score teeth that are up to seven shades whiter. Snap open each individual pack and apply to the fronts of teeth post-brushing, morning and night, for just seven days. Considering that most other systems take weeks to show results, this one is truly a must.

Type: Gel | Session Duration: 20 minutes | Active Ingredients: Hydrogen peroxide

What We Like

• Vegan formula

• 100% plastic-free system

• Sustainable packaging

What We Don't Like

• May cause slight gum irritation

In the market for a whitening product that’s both clean and sustainable? Look no further than this whitening gel from Bite. You may be familiar with Bite for its innovative and clean toothpaste “bites,” and now the eco-minded brand has launched the first and only 100% plastic-free teeth whitening system on the market. The glass bottle comes complete with a compostable brush to make application quick and easy.

But of course, more on the product itself: The vegan peroxide-based formula is gentle enough to be used by those with sensitive teeth, but trust, it works. Simply swipe on for two minutes, twice a day, and watch it work its magic. Each bottle contains enough serum for 28 applications, enough for a two-week supply. 

Type: Gel | Session Duration: 2 minutes | Active Ingredients: Carbamide peroxide

What We Like

• Whitens teeth while you align

• Non-sensitizing formula

What We Don't Like

• Can only use with aligner or retainer

If you’re currently rocking Invisalign or any other type of clear, corrective aligners, this pick is for you. “The foam keeps your aligners clean while whitening your smile simultaneously, so you get both straighter and whiter teeth at the same time,” says Dr. Marashi, who’s a fan. Oh, and did we also mention that it freshens your breath, too?

All you need to do is squeeze one pump of this 3-in-1 foam into your aligner or retainer trays, making sure it’s spread all over evenly. Then, pop them on and voilà! Simultaneously brighter, whiter, and straighter teeth.

Type: Gel, trays | Session Duration: Dependent on tray use

What We Like

• Reaches tooth crevices

• No sensitivity

What We Don't Like

• Reviewers say the formula feels gloppy

For those looking for a simple, easy option that can be used pretty much anytime, anywhere, this portable pen can’t be beaten. All you have to do is brush the whitening gel (which contains five times more hydrogen peroxide than other comparable products) onto each tooth—that’s it. What we appreciate most is how its flexible brush tip can get inside the crevices between your teeth, making eliminating tough coffee stains a breeze. The formula took over two decades to develop and boasts a water-resistant, hydrating base that both helps it adhere better to teeth and minimizes sensitivity. The latter is a point confirmed by reviewers, who also talk about how well and quickly it works.

Type: Gel | Duration: As long as it stays on | Active Ingredients: Hydrogen peroxide

What We Like

• Effective for improving health and teeth appearance

• Very hygienic and sustainable

• You get 365 uses out of one charge

What We Don't Like

• Expensive

Okay, so a toothbrush alone isn’t going to whiten your teeth, but this one can help you achieve your goal of pearly whites faster (especially when it’s paired with a good whitening toothpaste.) Reviewers report that their teeth were whiter and brighter. Credit the fact that yes, it’s a sonic toothbrush, but the first of its kind to combine silicone and polymer bristles to help more thoroughly break down plaque. It also has a built-in tongue and cheek cleaner, plus all kinds of other cool bells and whistles, such as 16 different adjustable settings.

Type: Toothbrush | Duration: 2 minutes | Active Ingredients: Silicone and polymer bristles

What We Like

• Reaches tooth crevices

• Easy to incorporate into your routine

• Goes on white so you can easily see where you’re applying it

What We Don't Like

• Reviewers dislike the taste/film left behind

To be honest, a professional, in-office whitening treatment is undoubtedly the best way to get the fastest whitening results. That being said, this at-home option is no slowpoke. When used as directed (i.e. applied to clean teeth overnight and brushed off in the morning), the hydrogen peroxide-based formula can whiten teeth by up to three shades in just two weeks.

Type: Serum | Duration: Overnight | Active Ingredients: Hydrogen peroxide

The drier your teeth are when you apply this, the better it will work.

What We Like

• Highly-effective

• Trays are custom made

What We Don't Like

• Causes irritation and/or sensitivity

• Expensive

Again, nothing compares to in-office whitening, but this is the next best thing. The gel touts a clinical-grade level of hydrogen peroxide, while the trays are custom-made just for you, meaning they are both super comfortable and fit your teeth to a tee for maximum efficacy. They can be worn daily for 30 to 90 minutes up to two weeks (making this a nice customizable option as well), though you can start to see results in as little as three days.

Type: Gel, trays | Duration: 30 to 90 minutes daily, for up to two weeks | Active ingredients: Hydrogen peroxide

Final Verdict

While teeth whitening can be dependent on the person, team Byrdie can’t go past the Crest 3D White Whitestrips with Light since they combine the brand's popular whitestrips with the power of blue light or the Crest 3D White Luxe Glamorous Whitestrips for their ease of use and American Dental Association’s (ADA) seal of approval. And when it comes to minimal effort, maximum impact, the Crest 3D White Brilliance Toothpaste (view at Bed Bath & Beyond) is gold class. Just switch your regular toothpaste out for this one and you’re golden.

What to Look For in a Teeth Whitening Product

The Application Method

Typically with at-home whitening, consistency is key, so it’s important the product you buy is one you’ll actually use. Check how it applies, how long it needs to be worn, and how often you’ll need to use it before you pull the trigger. 

Price Point

It’s no secret at-home products will never yield the same results as a professional treatment, so be sure to consider this when it comes to price. Exorbitant or inflated treatment kits will just leave you disappointed. That being said, our list is vetted by us to ensure you get results at a reasonable price. 

Potential Allergens or Irritants

It shouldn’t come as a surprise that at-home teeth whitening products can contain harsh or potentially irritating ingredients, especially if they come into contact with your skin. We suggest running any questions or concerns past your dentist or health professional first. 

FAQ

• How do teeth whitening products work?

  Dr. Marashi explains that teeth whitening products typically involve a peroxide gel that’s applied to the surface of the teeth, whether it’s delivered via foil, a strip, or a custom-molded tooth tray. The peroxide gel soaks into the tooth, dissolving internal discolorations. “Think of it as applying bleach to a cranberry stain on white fabric,” he says.

• Are teeth whitening products safe?

  According to Dr. Marashi, yes, teeth whitening products are safe. “Obviously, there may be some inferior products out there, but by and large, they are safe!” he says. A great way to know if an oral care product is up to par is by checking to see if it earned an ADA Seal of Acceptance.

• Can you avoid pain and sensitivity after using teeth whitening products?

  Some folks may be wary of using teeth whitening products as they’ve been known to cause minor tooth sensitivity. According to Dr. Marashi, you can avoid this by using a topical fluoride or desensitizing toothpaste after removing your whitening product.
