VieBeauti Teeth Whitening Kit
Pros
- Built-in timer
Cons
- Took awhile to see results, per some reviewers
Nearly 40,000 (!!) customers have left rave reviews about this kit—which must mean it’s great! For less than 30 bucks, it comes with a light unity, three syringes of whitening gel, one syringe of remineralizing gel, two moldable whitening trays, and a plastic storage case to keep your LED whitening tray clean. The five powerful LED bulbs in the light unit speed up the process of removing stubborn stains caused by things like food, coffee, and wine.
THE REVIEWS: “This whitening kit is easy to use,” wrote one reviewer. “It offers options if you don’t want to bother with fitting the upper and lower molds. I did follow instructions to fit mine to maximize the whitening. It also has a remineralizing solution to apply after whitening for sensitivity. I have sensitive teeth and this is key for me. I highly recommend this kit and would purchase it again.”

Cons
- Makes gum sore, per some reviewers
Leading New York City cosmetic dentist, Dr. Stephanie Dumanian, highly recommends this kit by GLO. “GLO products are top of the line. Their take-home whitening kit provides fast whitening results without being abrasive to your teeth or gum. The advanced technology GLO’s kit offers can help to amplify whitening results received in-office and help maintain those results over time.” Mind you, Dr. Dumanian is the reason behind the popular glimmering smiles of celebs like Busy Philipps and Ashley Park, so you know she’ll only suggest the best of the best.
THE REVIEWS: “I love this product!” one reviewer wrote. “I’m on the last day and my teeth are truly four shades lighter. I love the hands-free ability. I make my kid’s lunch, fold a load of laundry, do a little work, and watch some TV. It is a mild pain to have to reapply the lip protectant and whitening gel every eight minutes, but it’s better than any other option. I love how well this worked! I didn’t experience any sensitivity or issues with my lips. I’m so so so glad I invested in this product. It’s given me so much more confidence in my smile!”

Tons of buyers say that they were able to see super speedy results with this kit, and you only have to use it 10 minutes a day. Easy peasy!
THE REVIEWS: “I had never used a whitening product before, other than whitening toothpaste, because I have sensitive teeth. But this Colgate whitening kit caused no issues,” one reviewer wrote. It also visibly lightened the color of my teeth. Overall, I’m very satisfied.“
| Number of treatments included: | Applications for up to 4 times a year |
|---|---|
| Usage directions: | Apply the serum on each tooth—top and bottom. Wait 10 seconds in between the top and bottom rows of your teeth for them to dry. Then insert the LED light into your mouth and let it sit for 10 minutes. Do not eat or drink for 30 minutes after. Use once a day for 10 days. |

best whitening tray kit
Opalescence Go 15% Teeth Whitening Trays
Pros
- Gluten-free
Cons
- Burning sensation on gums, per some reviewers
Another one of Dr. Dumanian’s favorites! Here’s what she has to say about her top second pick that is known to be mess-free: “These prefilled teeth whitening trays are a convenient kit and easy to use. They eliminate the need for messy gels, and you can just pop them into place. They are a great option for individuals with sensitive teeth. Do keep in mind that trays are not one size fits all so they may not fully cover longer teeth, leading to an uneven whitening result.”
THE REVIEWS: “I am a coffee drinker and started to notice in photos my teeth were not as white as they use to be. It’s been about 3 months and I’ve purchased another box,” wrote one reviewer. “With the first box, I noticed a slight difference in three applications but by the 10th application, my teeth were four to five shades whiter. I use the whites of my eyes for comparison. I was very impressed. With the second box, I see dramatic results with just the second application. I’m thinking the stains are not as deep since I’ve used the product before. I absolutely recommend this product!”

Pros
- Great for travel
Cons
- The gel is runny which makes the process messy, per some reviews
If you’re looking for something that’ll give you pearly whites without breaking the bank, this bad boy is your ideal option. Ahem, where do I start? It’s near five-star rating? The 2,100 glowing reviews? Its under-$10 price tag? Clearly, it checks off a lot of boxes, but let’s get into the official stuff… You can use a mouth tray, toothbrush, or even a Q-tip for it to whiten your teeth which makes it very convenient. (Just follow the designated instructions on the box for the form of application you go with.) Because the gel can be manually applied to your teeth in multiple ways, this allows for the product to reach every single one of your teeth for an even look.
THE REVIEWS: “I’ve been using this product for several years. I get a lot of compliments on how white my teeth look,” wrote one reviewer. “I only use this three times a week. It’s not as expensive as the popular brands. I’m glad I found it on Amazon.“
| Number of treatments included: | Not listed |
|---|---|
| Usage directions: | Apply thin continuous line of gel onto mouth tray. Allow 5 minutes for bleaching agents to kick in and follow the directions based on your choice of application method (located on box). After at least 5 minutes, rinse mouth out to remove the remaining gel. Follow with Plus White StainGuard Rinse and Plus White Xtra Whitening Toothpaste for more whitening protection. For best results, use twice daily for 2 weeks. |

Depending on how bright you wanna go, you can choose between two different wands with this kit. The silver wand will whiten your teeth up to eight shades in nine minutes, while the gold one will white them up to 12 shades.
THE REVIEWS: “I was apprehensive to try this at first. The last few times I’ve whitened with my opalescence trays from my dentist, I’ve had extremely irritated and almost blanched-looking gums, so I haven’t been doing anything since. I decided to try Snow and with only 10 minutes on my first go, I was lightened two shades,” wrote one reviewer. “No irritation, no pain, no gross taste or consistency in mouth. I see I’ll have to do it more regularly, but I won’t mind because it’s a pleasant experience.”

|---|---|
| Usage directions: | First, brush your teeth, apply the proprietary teeth whitening gel, and then let the USB-powered mouthpiece work its magic. Make sure to rinse. |

THE REVIEWS: “This stuff really works!” one reviewer wrote. “I am on my third bottle. It very gently whitens and doesn’t bother me while it’s on. It has an extremely subtle mint flavor. The texture is a little thick but I’m not licking my teeth while it’s on. I barely notice it. Best of all, I don’t get terrible pangs of sensitivity like I used to with strips!“

MOON Teeth Whitening Kit
best vegan teeth whitening kit
MOON Teeth Whitening Kit
Pros
- Dentist-approved
Cons
- The device stopped working for some reviewers
Sometimes the gel and LED mouthpiece can get a bit sticky and slippery to work with. But with MOON’s whitening kit that uses dissolving whitening strips instead of gel, that doesn’t have to happen anymore. Plus, it’s super travel-friendly too thanks to its cordless design and the travel case that comes with the set.
THE REVIEWS: “I’m glad I went with this kit!” one reviewer wrote. “Whitening pens are more of a gimmick than a true whitening solution… and strips kill my teeth. I happened upon this kit in a search, and I’m happy I did! They legitimately made my teeth much, much whiter in the 14-day treatment cycle. I honestly don’t know how to tell whether they’re ’12 shades whiter’, but I can say it definitely works. It’s a fantastic product!”
| Number of treatments included: | 56 |
|---|---|
| Usage directions: | Apply MOON Dissolving Whitening Strips to upper and lower teeth. Gently insert Whitening Device into mouth and press button to power on. After 5 minutes, device will automatically power off. Remove device and allow up to 10 additional minutes for Whitening Strips to fully dissolve. No rinsing required! |

VVARDIS White Enamel Anti-Aging Serum
best strengthening teeth whitening kit
VVARDIS White Enamel Anti-Aging Serum
Pros
- Peroxide-free
Cons
- Expensive
It definitely is worth a lot more than a pretty penny, but it’ll def be worth your buck. I mean, the fact that it only requires two small products—a brush and a serum—to whiten your teeth up to 10 shades in just a week is pretty wild! And it’s got the stamp approval from Dr. Dumanian… “VVARDIS’s whitening serum kit which comes with a brush offers fluoride, bleach, and peroxide-free healthy whitening from the first application. It regenerates and strengthens enamel (the first of its kind to be recognized by the American Dental Association CDT).”
THE REVIEWS: “I applicated a very thick layer every night before going to bed for SIX nights in a row until the bottle was empty. My teeth are definitely whiter and they feel smooth and healthy,” wrote one reviewer. “I had no sensitivity or gum issues. I can really recommend this one-week intense healthy whitening treatment!”
| Number of treatments included: | Enough for 1 week |
|---|---|
| Usage directions: | Before bedtime, use the applicator brush and apply a thick layer of VVARDIS White Enamel Anti-Aging Serum to your exposed teeth, extending the serum over your gum line. It also safely whitens porcelain crowns and veneers. After applying, keep your lips drawn for 10-15 seconds. Don’t rinse, drink or eat, just go to bed. |

twice. Teeth Whitening Strips
Now 17% Off
Pros
- Vegan and sulfate free formula
Cons
- According to some reviews, people didn’t see until after than the indicated timeframe
The iconic Lenny Kravitz is one of the brains behind these whitening strips, and I feel like that’s all I gotta say?? But really though, with these strips, you won’t have to worry about your teeth or gums hurting during or after as they were thoughtfully made for those with high sensitivity. It contains dentist-recommended levels of hydrogen peroxide and coconut oil to whiten and reduce that sensitive/delicate feeling.
THE REVIEWS: “These are the BEST!” one reviewer wrote. “I have tried almost all whitening strips. They either skipped off my teeth, tasted awful, burned, or did not work. I could never finish a pack because of too much sensitivity. These Twice strips are amazing though!!! They really work and none of the bad stuff happens. My teeth are so white, and they were so easy to use. They stayed on, had good taste, and I am hooked! I bought some for my whole family! Thank you for finally a good solution to my smile. I love my white teeth!”
| Number of treatments included: | 20 |
|---|---|
| Usage directions: | Apply the sticky gel side of the strip against your teeth. Line up with the edges of your gums and apply gentle pressure to mold the strip securely to the teeth. Fold over teeth to secure. After 30 minutes of uninterrupted use, peel off strips and dispose. Brush teeth to remove any residual gel. Use once a day for 30 minutes for 5-7 consecutive days |

best chemical-free teeth whitening kit
Lumineux Teeth Whitening Kit
best chemical-free teeth whitening kit
Lumineux Teeth Whitening Kit
Pros
- Chemical-free
Cons
- The toothpaste and mouthwash don’t have a pleasant taste, per some reviewers
After practicing dentistry for nearly 30 years, Dr. Kourosh Maddahi founded his own brand of oral care that didn’t use harsh chemicals and alcohol. Then, Lumineux was born. Dr. Maddahi’s brand consists of fan-favorite products like whitening strips, whitening mouthwash, and a whitening toothpaste that includes natural ingredients like coconut oil, sage oil, and dead sea salt. And in this kit, you can get all of them in a single bundle! That glowing smile you’ve been dreaming of is just days away, my friend!
THE REVIEWS: “Okay, this stuff works amazingly well,” wrote one reviewer. “I have tried other higher-end whitening brands and they didn’t come close to what these products do. I think the star in this set is the mouthwash. It’s pretty powerful at whitening and it doesn’t make my teeth sensitive. None of these products do. The taste is unique but it’s not bad to me at all. My only gripe is the mouthwash bottle is usually the first thing I run out of because it’s easy to go through fast. I only use it once a day to make it last longer. But other than that I love this set!!! Highly recommend.“

best no-slip teeth whitening strip kit
Crest 3DWhitestrips Bright At-home Teeth Whitening Kit
Pros
- Can wear on-the-go
Cons
- Per some reviews, they made some people’s teeth sensitive
Personally, I love these strips because they don’t slip off. And honestly, that’s the number one thing I look for when it comes to this type of teeth-whitening method. Because if they’re constantly slipping and sliding off, what’s the point!! These puppies have a great grip and they’ve made my teeth look so luminous for years. I swear by ’em!
THE REVIEWS: “I really like these strips,” one reviewer wrote. “They are great for sensitive teeth, but still get the job done. I love how convenient they are. I can throw them on while doing my makeup and by the time I’m ready to hit the door my teeth are sparkling.”
| Number of treatments included: | 22, 11 for top teeth and 11 for bottom teeth |
|---|---|
| Usage directions: | Peel Whitestrips from backing liner. Apply using a mirror and apply gel side of strip to front teeth. Align straight edge of strip with gum-line. Fold over teeth and press to secure. |

best violet light whitening kit
Hismile VIO405 Teeth Whitening Kit
best violet light whitening kit
Hismile VIO405 Teeth Whitening Kit
Now 20% Off
Pros
- Paraben- and alcohol-free
Cons
- Light may be too strong on the eyes for some people
What’s so cool about the VIO405 Teeth Whitening Kit is that the mouth tray device uses 32 LED violet lights instead of the typical five which activates the brand’s PAP+ formula. The researchers behind this Hismile formula found that PAP (aka Phthalimidoperoxycaproic Acid), an organic peracid, is a safer alternative to peroxide. Used together, they’ll give you game-changing, noticeable results without the side effects that could happen with peroxide-filled kits just after one to two treatments.
MY REVIEW: I love that with the VIO405 Teeth Whitening Kit you’re basically getting ~exclusive~ treatment. It includes the world’s first at-home VIO405 light and its own whitening formula. And the fact that this set has over 12,000 glowing reviews to back it up with a near five-star rating explains it all, IMO.
| Number of treatments included: | 6 |
|---|---|
| Usage directions: | Apply a layer of PAP+ primer to each tooth. Wait 10 seconds then expel excess before beginning the whitening treatment. Each refill contains enough gel for a single whitening treatment. Twist off the cap, and apply half to the top of the mouth tray, and the other half of to the bottom of the mouth tray. Power on the VIO405 device by gently pressing and holding the Hismile logo on the front side of the device. Place the device in your mouth until the device automatically powers off after 10 minute treatment. Expel any excess gel and rinse mouth thoroughly with water. |
