Oral care is still up and coming in the clean beauty space. While you can find effective natural-leaning options to freshen up your smile, it does take a bit more detective work to identify a gentle, high-quality formula—especially when it comes to teeth whitening.
Why? Two words: hydrogen peroxide. The ingredient is one of the only widely studied ingredients for teeth whitening, yet many people claim it can make your teeth sensitive. That being said, it's very difficult to find whitening kits that skip it, especially since we don't have an alternative ingredient that provides just as pearly results.
However! We still have very strict standards when it comes to teeth whitening kits. We made sure the versions below contain no PEG compounds, triethanolamine (a common pH adjuster that has some toxicity concerns), or other iffy ingredients. Take a look, snag a set, and prepare to show off your brilliantly white smile.

This whitening gel toes the line between gentle and powerful, promising up to seven shades whiter in just one week. The whitening pen itself is powered by hydrogen peroxide, but I personally don’t find it to be irritating (and I have pretty sensitive gums). It includes 20 treatments, as well as a patented 20-LED light (with an automatic 10-minute timer) to boost your results and an enamel-strengthening pen for whitening aftercare.
What our tester says
This is the whitening kit I personally use, and I noticed a shinier surface after just one round. As I mentioned, I have pretty sensitive teeth and gums, but I experienced no pain with this whitening gel. The pen is easy to use, and the gel doesn’t taste too funky, which is a feat for whitening formulas—it even has a slight peppermint flavor.
Countless reviews echo my praise: “I still get compliments on how bright my teeth are months after I used it,” one shopper writes. “The gel is easy to apply. The blue light is so convenient being able to plug up with your cell phone for power.”

This on-the-go whitening pen features hydrogen peroxide to easily lift stains, as well as lavender oil, honeysuckle flower extract, and strawberry fruit extract to provide anti-inflammatory and antioxidant properties. Not to mention, it includes light-reflecting pigments for an instantly brighter smile. A great option for instant gratification!
The kit also includes a whitening toothpaste with sodium fluoride, peppermint oil, and a host of antioxidants, along with a “booster dust” you can use to manually buff away stains. The dust contains kaolin and bentonite clays, white turmeric, and sodium bicarbonate to physically lift discoloration—it’s like an exfoliating scrub for your teeth. Simply dip your pasted toothbrush into the dust one to two times per week to enhance your whitening results.
What our tester says
I love the ease of a portable whitening pen (I’ve written about it before), and this design is especially chic, user-friendly, and easy to tuck into just about any tote I own. I haven’t seen the most dramatic whitening results, but I will say that the easy application makes this one an A+ option to use every day.
This reviewer agrees: “The size is a big advantage compared to other products because it is basically the size of a sharpie pen. This is super convenient for putting in your pocket or purse and allows you to apply it whenever. I bring this up because I notice my teeth are whitest right after applying the product.”

Best with LED: GLO Science GLO Brilliant White Smile At Home Teeth Whitening Device
:view on Glo Science | $159:view on Amazon | $159:view on Sephora | $159
Pros
- Comes with lip care to simultaneously soften lips
- Clinically-backed results
- Easy to use device
Cons
- Requires three 8-minute treatments per day
Active ingredients:
Hydrogen peroxide
Price:
$159
Subscription discount?:
No
Number of treatments required:
15
Treatment length:
8 minutes
“While it’s not an active ingredient, an LED light can help facilitate the whitening process,” says premier cosmetic dentist Victoria Veytsman, DDS. “This is because the LED light kickstarts a chemical reaction to help speed up the breakdown of peroxide, the active ingredient in the solution that gets applied to your teeth. This allows the peroxide to fizzle any stains off the teeth at a faster pace, leaving you with whiter teeth in less time.”
This kit includes a patented LED mouthpiece with five clinically-backed teeth whitening treatments (enough for three 8-minute sessions over five days). The mouthpiece calls upon the brand’s advanced heat technology to reach an optimal temperature that whitens teeth faster and brighter. In fact, a study conducted by the brand showed that three 8-minute daily applications, over five days, resulted in an average improvement of 10 shades.
What users say
It’s difficult to choose just one glowing review, but I think this one says it best: “[This] whitening device brightened my teeth and gave me back confidence in my smile again. I am a heavy coffee and tea drinker and felt my smile was not as bright as before. I was ashamed of it. After using this whitening device, I can see gradual improvement day by day. The instructions are super easy to use, and it is convenient to do every day.”

Best for sensitive teeth: Lumineux Teeth Whitening Kit
:view on Amazon | $45
Pros
- Peroxide-free
- Most natural option
- 30-day money back guarantee
Cons
- Some reviewers say the strips easily stick to each other
Active ingredients:
Coconut oilSage oilLemon peel oilDead sea saltXylitol
Price:
$45
Subscription discount?:
No
Number of treatments required:
4 days in a row, then once a week as needed
Treatment length:
30 minutes
Some folks are fans of strips, since the adhesive evenly coats the tooth’s surface and leaves little room for error (whereas with a pen or tray, you must manually brush on the whitening gel). And if you’re looking for peroxide-free strips (which are hard to find!), you can’t go wrong with this Lumineux kit: The strips contain natural brighteners, coconut oil, sage oil, and lemon peel oil, while the pinch of Dead Sea salt delivers precious minerals—calcium, potassium, and magnesium, to name a few—to your enamel and gums.
To amp up your results, feel free to brush with the natural whitening toothpaste and take a swig of the alcohol-free mouthwash—both of which include xylitol to help strengthen enamel.
What users say
“These are the best toxin-free whitening strips I’ve found,” writes one reviewer. “They don’t cause any sensitivity, and you can see a difference with just one use.”
Some people say the super-thin strips can easily stick to the packaging, but it seems storing them in a cool area helps with that issue. “Store them in a cool place. Not the bathroom,” one shopper writes. That’s the mistake I made at first, and the bottom strip would not come out of the package properly so the bottom strip would then be wasted…when you store them in a cooler place, there are no problems, and boy do they work!”

Best for tough stains: Dr. Brite Wireless Advanced Whitening System
:view on Dr. Brite | $200

- Strengthens enamel
- Booster pen enhances results
Cons
- Pricey
Active ingredients:
Hydrogen peroxidePeppermint oilHydroxyapatiteChamomile flower extractCarbamide peroxide
Price:
$200
Subscription discount?:
Yes
Number of treatments required:
1-2, then as needed
Treatment length:
10 minutes
This “Advanced Whitening” kit includes two types of gels: a standard whitening gel to use with the LED-powered tray (which offers both blue and red LED light), and a “Brite Booster” pen to really elevate your results. Each formula features hydroxyapatite, which is a naturally occurring mineral that makes up 97% of tooth enamel, so it simultaneously strengthens teeth as it whitens. It does come with a steep price tag, but you’ll only have to buy the full device once—the pen refills are $50 a pop.
What users say
Despite the hydrogen peroxide, reviewers say there’s little to no sensitivity involved with this system. “This is the best whitening system I have used,” one shopper writes. “I have not experienced any sensitivity and usually with other products I get extreme sensitivity. I 100% would recommend.”
And users are notably impressed by the formula’s ability to lift years-long stains with ease. “[I] have always been embarrassed by my yellow teeth and felt like I couldn't even smile with teeth showing,” one reviewer shares. “Now, I feel like I’ve got to show them off…I even had someone DM me on Instagram asking if I had edited my teeth to look whiter.” That’s when you know it’s good!

What users say
Users definitely notice a change in just a few days. “I drink a lot of hot herbal tea every day, and my teeth were a little stained from the tea. I already can tell a difference after five days,” one shopper recounts.
Even the nonbelievers are floored! “If I'm being honest, I was skeptical at first [because with] every other whitening product I've tried before I saw no results or it would make my teeth sensitive,” says another reviewer. “This, I must say, I saw results within two sessions [and] no sensitivity at all. I recommend it 100%.”

What to look for
Here's what to consider when purchasing a kit:
1.
Peroxide content
"Peroxide is the most common ingredient in teeth whitening kits," says Veytsman. "When looking for whitening strips, gels, pens, etc., some concentration of peroxide should be on the ingredient list, whether in the form of hydrogen peroxide, carbamide peroxide, etc. Peroxide is the active ingredient that works to oxidize or 'fizzle' the stains off, leaving you with a brighter, whiter smile."
However, if you have sensitive teeth, you might want to look for a lower concentration of peroxide, like carbamide peroxide. "Carbamide peroxide is actually a little more gentle," says board-certified endodontistAlexa Martin, DMD. Research has shown that a 16% and 35% carbamide peroxide concentration1 are effective and safe for teeth without additional side effects (aside from some sensitivity).
2.
Enamel-strengthening ingredients
Especially if you do have sensitive teeth, you'll want a product that simultaneously strengthens and soothes your gums and enamel. Think anti-inflammatory ingredients like aloe vera (which actually functions as a natural tooth brightener), vitamin C, xylitol, hydroxyapatite, and other botanical extracts.
3.
Form
Teeth whitening products come in various forms, the most common being gels, strips, pens, and trays. Gels tend to be the most potent, which means they may also cause the most sensitivity.
"Pens and strips tend to have a lower percentage [of peroxide] but will also be easier to 'clean up' if you're on the go (like driving)," says Martin. "Strips are great to store in your bag for vacation [or] to use while you're getting ready." Choose your own adventure here, depending on your lifestyle and commitment level.
Are teeth whitening kits safe?
At-home teeth whitening kits are totally safe—assuming you use them correctly. Always follow the instructions on the product, and always speak with a dentist if you have any specific concerns.
"If you have any gum issues, gum recession, cavities that haven't been treated, or extreme teeth sensitivity, I would recommend being extra careful when using at-home whitening kits," adds Veytsman. "I also suggest connecting with your dentist should you experience any discomfort when using whitening products or dental products in general."
The most common side effect from whitening products is sensitivity and irritation, likely from the peroxide. "The peroxide, the same way it stings when you put on a wound, is irritating to the soft tissue inside the tooth, which contains thousands of nerve endings," says Martin. "Start slow [with] shorter windows of time, and see how your teeth respond."
Some people can only handle whitening once or twice a week, and that's OK! But according to Martin, the discomfort shouldn't last for too long: "Studies show that even if you get irritation during the bleaching (sometimes your gums around your teeth will be sore and white, too!), it's completely reversible," she notes.
You'll still want to avoid staining your gums with the product the best you can, but rest assured that any irritation should ebb. If it doesn't, that's your sign to consult a professional.
How teeth whitening impacts health & longevity
Wanting whiter teeth isn't only about the aesthetics. A brighter smile is nothing to brush off, of course, but a whiter smile is often a healthier smile—and oral health is crucial for longevity.
Your mouth, after all, is the gateway to your body and the beginning of your gastrointestinal tract, and your gut affects virtually every function of your body.
"[Your mouth] is right next to the brain," functional medicine psychiatrist Kat Toups, M.D., says on the mindbodygreen podcast. "And what's in the mouth and nose can travel right up into the brain so easily." In fact, the bacteria P. gingivalis, the key pathogen in periodontitis, was identified in the brain of Alzheimer's disease patients2. Another study suggests a possible link between F. nucleatum 3(another periodontal pathogen) and Alzheimer's disease3.
That being said, you should prioritize oral care for the sake of your overall health. It may take more than a whitening kit to secure a healthier smile, but it's not a bad way to start—especially when you use these clean, high-quality options.
The takeaway
Looking for clean oral care? You can't go wrong with any of these teeth whitening kits, though I personally love SmileDirectClub's user-friendly design and MOON's on-the-go ease. Consider these formulas an investment for a brighter smile—arm yourself with a whitening toothpaste, too, to really elevate your routine.
