These Are the Best Whitening Toothpastes, According to Dentists (2024)

Noticeably brighten and whiten teeth while brushing with Colgate’s game-changing whitening toothpaste, a GH Beauty Award winner. The formula contains high levels of bleaching active hydrogen peroxide to brighten teeth one to two shades lighter, fast.

After analyzing the brand's data, our experts in the GH Beauty Lab confirm that this formula can remove up to 10 years of yellow stains on teeth in only four weeks of twice-daily use. "It works!" one Walmart reviewer raved. "I drink a lot of coffee and tea, and I noticed that my teeth are so much whiter after using this toothpaste."

Colgate Optic White contains gentle abrasives to scrub stains and polish teeth. It's the only American Dental Association-approved bleaching toothpaste that is formulated with fluoride for cavity prevention. It forms a protective layer on teeth, allowing the hydrogen peroxide to continue its whitening action beyond time spent actively brushing.

Ingredients: Hydrogen peroxide, hydrated silica, fluoride | Size: 3 oz.

This formula harnesses the power of Arm & Hammer baking soda to naturally lift stains. Grace Yum, D.D.S., a board-certified pediatric dentist in Chicago, says dentists in her office who treated college kids and parents used this toothpaste to keep their teeth white after professional in-office bleaching.

The brand claims it gently removes up to three times more plaque even in hard-to-brush places. Those who've ever tried baking soda as a teeth whitener know that it comes with a bit of a grimace, though: "Not the greatest-tasting, but that is a small sacrifice for healthy teeth and gums," says one shopper.

Catering to both sensitive teeth and gums, the Crest Pro-Health Gum and Sensitivity toothpaste garners notoriety for its effective (yet gentle) stain-lifting powers. In fact, it's the only ADA-approved toothpaste that targets both sensitivity relief and whitening, an anomaly in whitening toothpaste.

The formula goes by route of less aggressive surface stain removers like hydrated silica and stannous fluoride, a known favorable ingredient for sensitive teeth, according to Dr. Becker. This Crest formula offers a light minty-fresh taste that shoppers say tastes great. It also boasts a foamy formula sans grittiness. Most online reviewers reported noticeable whitening effects after about four weeks of use, which is longer than some other picks, but still effective.

No need to dread the teeth-scraping portion of your next dental cleaning. Switching to the Colgate toothpaste about three months prior to her dental visit, Birnur K. Aral, Ph.D., the executive director of the GH Beauty Lab, heard praise from her own dentist for the significantly less plaque buildup on her teeth. "I am happy I found a toothpaste that can keep plaque under control and has whitening properties at the same time!" she says.

This multi-tasking Colgate toothpaste helps fight cavities, whiten teeth and dissolve plaque, the latter of which may be thanks to its hydrated silica. In addition to whitening power, it also has gentle stannous fluoride that works to offset the sensitivity some people experience when using whitening toothpaste. Many shoppers enjoyed the refreshing feeling, but others found it a bit strong at first.

Those with sensitive teeth who want pearly whites without that harsh pang from sipping a cold beverage: Enter Sensodyne. Dr. Lipari recommends this extra whitening pick for his patients with sensitive teeth. Rather than focusing on brightening alone, it also uses a dose of stannous fluoride, which prevents sensitivity and hardens the tooth surface. The hydrated silica gently scrubs stains while potassium nitrate protects teeth against sensitivity. Its formula claims to decrease sensitivity after two weeks of regular use.

One GH editor and her entire family use Sensodyne. "It's great if you already have sensitive teeth and gums but don't want to slack on the whitening. Online reviewers echoed that sentiment, writing: "If you have sensitive gums, please do yourself a favor and try this!"

Ingredients: Potassium nitrate, hydrated silica, sodium fluoride | Size: 4 oz

Get a professional-looking polish without the major markup. Lauren Becker, D.D.S., a general and cosmetic dentist in New York City, names the Crest HD two-step whitening system as her favorite over-the-counter whitening product that "gives patients noticeable results in under a week's time."

Carving out less time than whitening strips, the two-minute application substitutes your normal brushing routine. The first step cleanser helps remove plaque and protects against sensitivity, while the second step contains whitening and brightening hydrogen peroxide, says Dr. Becker. Not to mention, unlike strips, these whiten the back of your teeth, too.

No need to think twice when reaching for this whitening toothpaste. Jonathan B. Levine, D.M.D., a board-certified dentist and an associate professor at the NYU School of Dentistry, recommends the TWICE toothpaste line because it's "ingredients that are safe and help to remineralize the teeth" with its low abrasive index numbers. Translation: It's gentler on teeth.

It's made with vitamins A, E and aloe vera that the brand claims to support gum health and freshen breath. Several online reviewers called it "refreshing" and agreed that it left breath smelling better. "This toothpaste is so good!" an online shopper raves. "I love the taste and the feel: Super clean and very fresh! My teeth are even a little whiter."

Standing out among "natural" toothpaste brands by earning ADA approval, Tom's of Maine Simply White is a shining example of why the brand is well known in the natural products realm. For those who wish to steer clear of conventional toothpaste due to worries about ingredients, production methods or personal preferences, this selection is a suitable natural alternative that still whitens teeth.

Similar to most whitening toothpaste options, it's formulated with hydrated silicas to effectively remove surface stains and fluoride for cavity prevention. One GH editor enjoyed its subtle minty freshness but found it offered more of a gel-like consistency than a traditional thick paste, as a matter of personal preference.

Ingredients: Hydrated silica and fluoride | Size: 5.5 oz

The GH Institute's Beauty Lab rigorously tests all types of oral care, including water flossers, toothpaste, whitening strips and more. For past whitening product tests, scientists measure testers' tooth shades under standardized lighting before and after using a label-masked teeth whitening product as directed over a specified time period to gauge changes in tooth color.

Testers also evaluate the products at home on factors such as ease of use, flavor, tooth sensitivity, cleaning efficacy (if applicable) and perceived whitening effects. Beauty Lab scientists then tally hundreds of data points to determine the top performers. While we haven't tested this category at large, the picks we included on this list were either approved by dentists, analyzed by our team of chemists or have ADA acceptance, meaning the organization supports that its efficacy and safety claims are backed up by clinical research.

✔️ Active ingredients: The dentists we spoke with unanimously agreed that bleaching agents hydrogen peroxide or carbamide peroxide are key ingredients in whitening toothpaste. For peroxide ingredients, the maximum percentage is 10% for over-the-counter products, says Sharon Huang, D.D.S., M.I.C.O.I., a cosmetic dentist and founder of Les Belles NYC. Hydrated silica acts as a polishing agent to help remove stains. Baking soda also works to that effect while raising oral pH, adds Dr. Levine. Low pH levels mean high acidity, which can lead to demineralization, or the layer of protective enamel wearing down. This can make teeth more prone to cavities and other damage.

✔️ Sensitive-friendly formulas: Those with sensitive teeth may look for a formula with potassium nitrate, which is known to reduce sensitivity. Fluoride also helps prevent sensitivity and hardens the tooth's surface, according to a study. There are also products that don’t contain peroxide and instead are made with ingredients like aloe vera and coconut oil, which have natural whitening effects that pull stains from the teeth, according to Dr. Huang. "They're not as effective as peroxide, but are a good natural option that’s gentler on the teeth," she notes.
