The same way you need special glasses to look at a solar eclipse, that’s how blindingly white I want my teeth to be. Obviously, this is a lofty goal, but I’ve been working toward it by experimenting with the best teeth whitening kits. This isn’t my first foray into teeth whitening. As a teen fresh out of braces, I tried multiple in-office treatments. Since then, I’ve tested everything from overnight whitening strips to charcoal toothpaste that stained my sink an unfortunate shade of black.
Vogue’s Favorite Teeth Whitening Kits:
Personally, at-home teeth whitening kits have worked the best for both my budget and lifestyle. Unlike strips, these usually combine technology, like LED lights, with active ingredients like hydrogen peroxide and carbamide peroxide that do the actual whitening. And fortunately, today’s top at-home teeth whitening kits can target both surface stains and deeper discoloration from coffee, tea, wine, soda, and tobacco.
Below, we asked three board-certified cosmetic dentists to break down how these whitening kits work, what makes teeth look whiter, how to choose the right one for your needs, and eight options worth trying.
In This Story:
Best Overall: Colgate Optic White ComfortFit Teeth Whitening Kit
- Why We Love It: There’s a level of trust that comes with using Colgate’s dental products, one built over years of growing up with the brand. But just like you, the brand has evolved and now offers whitening kits as part of its repertoire. Cosmetic dentist Dr. Anjali Rajpal explains that Colgate’s whitening kit uses a 9% hydrogen peroxide-based gel, which is a reasonably strong concentration, paired with a flexible LED tray that offers a more tech-forward and comfortable fit. The trays also have a built-in tech element, as each one plugs directly into your iPhone or Android device for power. “It is a little pricier and requires consistent use, but it should generate good results,” she says. The brand recommends using the system for 10 days in a row for best results.
- Key Ingredients: Hydrogen peroxide
- Type: LED whitening light, teeth whitening pen
- Number of Treatments Included: N/A
- How to Use: Apply a thin layer of the whitening serum to your teeth, then use the LED device to illuminate your smile for 10 minutes. The brand recommends leaving the serum on overnight, but you can also brush your teeth to remove the dried formula sooner.
Best Whitening Strips: Crest 3D Whitestrips With Light
- Why We Love It: For those more comfortable with strips than trays, this whitening kit from Crest is both convenient and easy to use. Cosmetic dentist Dr. Jaskaren Randhawa explains that it combines a peroxide-based gel containing 10% hydrogen peroxide with an LED light to enhance the whitening process. “A higher at-home concentration of hydrogen peroxide ensures a more effective and noticeable outcome,” she says. “From a clinical perspective, this is a well-balanced product that can safely whiten teeth over time, making it a reliable at-home option. The addition of light accelerates the chemical breakdown of stains, providing faster results compared to traditional strips.” However, Dr. Rajpal notes that they may cause some tooth sensitivity, so keep that in mind if you tend to lean on the sensitive side.
- Key Ingredients: Hydrogen peroxide
- Type: Whitening strips, LED light
- Number of Treatments Included: 10 treatments
- How to Use: Apply the whitening strips to your upper and lower teeth once a day for one hour. After removing the strips, place the light on both the upper and lower teeth until it turns off automatically.
Best for Strengthening: Snow Teeth Whitening Kit
- Why We Love It: For teeth as white as snow, Dr. Randhawa recommends this kit for its ability to “effectively whiten teeth while strengthening and repairing enamel.” She explains that it contains hydroxyapatite to remineralize, rebuild, and strengthen enamel, along with potassium nitrate, which helps reduce tooth sensitivity. “The whitening serum contains a 6% hydrogen peroxide concentration, which breaks down stains, and the formula is sulfate-free,” she adds. And for those who often deal with zingers, she reassures: “This combination of active ingredients whitens teeth while also maintaining enamel health and minimizing sensitivity.”
- Key Ingredients: Hydrogen peroxide, carbamide peroxide
- Type: LED whitening mouthpiece, teeth whitening pen
- Number of Treatments Included: N/A
- How to Use: Brush your teeth, apply the Diamond Serum using the wand, then wear the LED mouthpiece for 10 to 30 minutes.
Best for Sensitive Teeth: Moon The Teeth Whitening Device System
- Why We Love It: For a whitening system that is free from potentially harmful ingredients such as SLS, SLES, parabens, artificial flavors, and animal by-products, consider Moon. Dr. Randhawa explains that the system uses a hydrogen peroxide–based gel with a 6% concentration, combined with LED light technology to help accelerate the whitening process. So no matter how much coffee or red wine you’ve had over the years, “this combination effectively targets surface stains,” she says. However, Dr. Rajpal notes that it has limited clinical proof compared to other kits, so it may not deliver results as dramatically or as quickly.
- Key Ingredients: Hydrogen peroxide
- Type: Whitening strips, LED whitening mouthpiece
- Number of Treatments Included: 56 dissolvable strips
- How to Use: Apply the whitening strips to your upper and lower teeth, then insert the mouthpiece and press the button to turn it on. It will automatically turn off after five minutes.
Best for Surface Stains: Auraglow Teeth Whitening Kit
- Why We Love It: This kit strikes the perfect balance between affordability and effectiveness. It uses a 35% carbamide peroxide-based gel in tandem with an LED light to accelerate the whitening process. While the results may not be instant, Dr. Rajpal notes that it “delivers results gradually,” making it a reliable pick for those who prefer a gentler approach.
- Key Ingredients: Carbamide peroxide
- Type: Carbamide peroxide gel syringe, LED whitening mouthpiece
- Number of Treatments Included: 20
- How to Use: After brushing your teeth and charging the LED whitening light, apply a thin line of gel to the top and bottom of the tray. Insert the tray, tap the logo to turn it on, and wear the device for 30 minutes for best results.
Best for Deep Discoloration: iSmile Teeth Whitening Kit
- Why We Love It: If you’re “so over” strips, Dr. Wagner says LED mouthpieces like this one, which keep the whitening agent in place, often perform better. “Think about your lifestyle and your level of sensitivity. If you have 10 to 15 minutes a day and want a deeper, all-over brightening, something like the iSmile LED tray system can be a great fit.” He explains that this kit combines a carbamide peroxide gel with a light-activated tray to help ensure even coverage across all your teeth. “It’s a solid option for people looking for a deeper, more uniform whitening effect at home.”
- Key Ingredients: Carbamide peroxide
- Type: Carbamide peroxide gel syringe, LED whitening mouthpiece
- Number of Treatments Included: 22
- How to Use: Remove the cap from the whitening gel syringe and apply 0.3 to 0.5 mL of gel to the inner front surface of the tray on both the top and bottom. Insert the tray and light into your mouth, pressing it firmly against your front teeth. Press the power button to turn on the light and whiten for 10 minutes. Afterward, remove the tray and rinse your mouth with warm water.
Best Budget: Ollm Teeth Whitening Kit Gel Pen Strips
- Why We Love It: Dr. Wagner describes this kit as a “clever hybrid,” combining the precision of a pen with the ease of a dissolvable strip. “It’s great for targeting specific spots or touching up after a longer whitening cycle, and users love the convenience and low mess factor.” Unlike many at-home kits that require bulky devices or a big time commitment, this one is low-maintenance and travel-friendly, offering flexibility without the need for chargers or accessories.

- Number of Treatments Included: N/A

Whether you’re tackling surface stains or deeper discoloration from coffee or wine, you’ll notice a brighter smile after just 15 minutes. For best results, the brand recommends using it consistently. Each kit includes 14 days’ worth of whitening via whitening strips as well as a whitening pen for touch ups.

Everything You Need to Know
Do teeth whitening kits actually work?
The short answer: yes. The long answer, according to our experts, is that many teeth whitening kits are effective, but their success depends on the product type, ingredients, and the individual’s dental condition, including factors like enamel thickness and natural tooth shade. Dr. Randhawa recommends kits that contain hydrogen peroxide or carbamide peroxide, which are commonly used in professional-grade treatments and are generally effective at lightening teeth.
However, she notes that results vary based on the severity of staining, how consistently the product is used, and whether the stains are intrinsic (deep within the tooth) or extrinsic (on the surface). “Non-peroxide kits may not work as well, and some may contain preservatives that could potentially become acidic,” warns Dr. Rajpal.
Dr. Randhawa also adds, “It is important to note that whitening thin or gray teeth can be particularly challenging, as these teeth may not respond as effectively. While over-the-counter kits can offer more gradual results, professional treatments typically provide faster and more dramatic improvements.”
Are the best teeth whitening kits safe to use?
“When used correctly, most over-the-counter teeth whitening kits are safe,” says Dr. Randhawa. However, she emphasizes that it’s important to follow the instructions carefully to avoid overuse, which can lead to tooth sensitivity or gum irritation. For those with sensitive teeth or gums, she recommends choosing a kit specifically formulated for sensitivity, plus consulting with a dentist before beginning any whitening treatment. “Caution should be exercised with DIY whitening methods, as improper use can cause damage. It’s also crucial to avoid swallowing the product, as some ingredients may be harmful if ingested.”
What makes teeth look whiter?
Dr. Randhawa explains that teeth appear whiter when surface stains are removed, revealing the natural color of the enamel. Common causes of staining include foods and drinks such as coffee, tea, and red wine, as well as smoking, all of which can lead to the buildup of extrinsic stains on the enamel. “The brightness of teeth is also influenced by the thickness and quality of enamel, which is the outer protective layer of the tooth,” she says. Over time, enamel naturally thins due to aging, bruxism (teeth grinding), or prolonged exposure to acidic foods and beverages. “This thinning exposes more of the yellowish dentin beneath, contributing to a duller appearance.”
Whitening treatments can help restore the look of your smile by either removing surface stains or reducing the visibility of yellowing. Whitening gels with active ingredients like hydrogen peroxide or carbamide peroxide contribute to this process by penetrating the enamel. “These compounds work by breaking down stain molecules and chemically bleaching the enamel, lightening the overall tooth shade. Scientific studies have shown that hydrogen peroxide, in particular, is an effective bleaching agent, as it releases oxygen molecules that break apart the chromophores, color-producing molecules, in stains, resulting in visibly brighter teeth,” explains Dr. Randhawa.
In addition to whitening, treatments that strengthen and protect enamel, such as remineralizing agents or fluoride treatments, can help preserve tooth structure and prevent further discoloration, enhancing long-term results. Dr. Randhawa also stresses the importance of routine dental cleanings for maintaining a bright smile.
How to Choose a Teeth-Whitening Kit
If you’re looking for faster whitening and more intense results, Dr. Rajpal recommends choosing a hydrogen peroxide gel. “However, if you prefer gentler whitening with longer-lasting results and less risk of sensitivity, you may prefer a carbamide peroxide gel. The most beneficial kits are those that contain either hydrogen peroxide or carbamide peroxide, which are the same active ingredients used by dentists, just in lower concentrations,” she explains.
Dr. Rajpal also notes that whitening strips are easy to apply and mess-free, making them a good option for those who want simplicity. LED kits may require more setup, but they often provide a stronger and more customizable whitening experience. Gel pens are convenient for quick touch-ups, though they may not deliver long-lasting results.
When selecting a whitening kit, it’s important to consider factors such as the type of stains you’re targeting (surface level versus deeper stains), your level of tooth sensitivity, and how much time you’re willing to commit to the treatment. Dr. Randhawa also advises checking whether the product has the ADA (American Dental Association) Seal of Acceptance or other professional endorsements to ensure its safety and effectiveness. “It’s important to note that while whitening kits are effective for removing surface stains, they are not designed to treat deeper, intrinsic stains. These types of stains typically require more advanced in-office procedures,” says Dr. Randhawa. Additionally, she reminds us that dental restorations such as bondings, crowns, and veneers will not whiten with these treatments. “Any whitening effect will apply only to natural tooth enamel. Lastly, if you have any concerns or pre-existing dental issues, it’s always a good idea to consult with your dentist before choosing a whitening kit to ensure the best and safest approach for your needs.”
