Pros
- 30-minute timer built in
- Includes 20 whitening treatments
- 60-day returns and a 2-year warranty for defects or manufacturing issues
Cons
- 35% carbamide peroxide may cause sensitivity and pain for some users; it’s a high amount of peroxide for at-home use

Our Thoughts on Auraglow Teeth Whitening Kit
Auraglow Teeth Whitening Kit is our pick for the best overall teeth whitening kit because it contains 1 rechargeable LED accelerator light, 2 syringes of 35% carbamide peroxide gel (20 treatments), a storage/charging case, and a charging cable for $48. Between our tester’s high praise and the price for one kit, we think the value proposition of Auraglow’s Teeth Whitening Kit is a standout.
Kendall tested Auraglow Teeth Whitening Kit and was really impressed. “This is my second time using this kit,” she said. “The results are noticeable and fast; I could see a visible difference in just two days of use.” Kendall rated effectiveness a 5 out of 5. If you’re getting ready for a major presentation and you can tolerate stronger peroxide, Auraglow offers speedy, noticeable brightening on a timeline that fits neatly around a typical workday.
When it comes to comfort and ease of use, Kendall found Auraglow’s kit to be incredibly user-friendly. “The guard is comfortable to wear, the application process is straightforward, and each 30-minute session fits easily into my routine,” she said, rating it a 5 out of 5 in this category.
Kendall didn’t experience any unpleasant taste while testing this whitening kit. “My mouth does fill up with saliva and creates quite a bit of foam during use, but that’s a normal part of the whitening process, and it simply feels like having mouthwash in your mouth, nothing off-putting,” she said.
“The only minor issue I encountered was that the power button is quite sensitive,” Kendall said. “If you accidentally touch it during a session, it will restart the 30-minute timer, which can be a bit frustrating. However, this is a small inconvenience that doesn’t detract from the overall quality of the product.” She rated button sensitivity a 3 out of 5.
She rated the value a 5 out of 5. “For the price point, the value is excellent, especially considering the kit comes with 20 days of treatment sessions. Overall, I’d definitely recommend this product to anyone looking for an effective and convenient at-home whitening solution.”

SNOW Teeth Whitening Kit
| Fortune score | 4.5/5 |
at SNOW
- Our thoughts: Our tester says this kit is very comfortable to use
- Who it’s for: Professionals with tooth sensitivity who want a comfortable, hands-free whitening setup
- What makes it different: We like that the LED mouthpiece plugs into your phone
Pros
- Lightweight mouth tray
- Uses USB-C
- Case is travel-friendly
Cons
- Currently sold out

Our Thoughts on SNOW Teeth Whitening Kit
SNOW’s Diamond Series is our pick for the best teeth whitening pen because it’s easy to apply and offers noticeable results without sensitivity (in our tester’s experience). With SNOW’s kit, you use the pen to apply a whitening serum to your teeth, and then put the LED mouthpiece in. The mouthpiece has a USB-C connection, so you can plug it into your phone and multitask while you whiten – great news for busy professionals who want a brighter smile on their own timeline.
Charlotte tested SNOW’s Diamond Series Teeth Whitening Kit.
She rated the whitening effectiveness a 5 out of 5: “I love using this product. It is so comfortable and easy to use! The tray comes with a sleek case to keep it in, and its light weight and easy to store,” she said. “The kit comes with whitening serum you will apply to your teeth, and then just pop the LED mouthpiece in for 10 to 30 minutes. The tray itself kind of feels like a mouth guard I used to use in sports, but more comfortable. I also love that it is a USB-C connection, so I just plug it into my phone and use it while I scroll on social media or read.”
When it comes to sensitivity, Charlotte was worried about using a strong LED light to whiten her teeth for extended periods. “I haven’t noticed any issues with my sensitivity. The light can make my teeth feel a little warm, but I wasn’t in any pain drinking cold water after. It does tell you to wait 30 minutes before eating or drinking anything, so maybe that helps a bit. However, for my worries, this completely blew me away.” She rated comfort and ease of use a 5 out of 5.
Overall, Charlotte noticed brighter teeth within two uses. “I do have pretty good dental hygiene and already have white teeth, but this made them even brighter,” she said. “I was scared it was going to highlight a small stain on my front tooth, but it hasn’t at all! I highly recommend this product.”
For professionals who like to multitask, SNOW’s plug-into-your-phone LED tray makes it easy to whiten while you answer emails or catch up on reports.
Specs:
- Active ingredient: Hydrogen peroxide, carbamide peroxide, and Nano-Hydroxyapatite
- Whitening method: Tray with LED light
- Treatment time: 9 to 30 minutes for 21 days
Best for Beginners: Crest Whitening Strips
Crest Whitening Strips
| Fortune score | 4/5 |
at Crest
- Our thoughts: Great for surface stains and ease of use
- Who it’s for: Professionals trying whitening for the first time who prefer strips over devices
- What makes it different: Has the ADA Seal of Acceptance, meaning the American Dental Association approves of it
Pros
- Easily accessible, sold at your local pharmacy
- Backed by the ADA Seal of Acceptance
- No devices required
Cons
- Requires consistent use over multiple weeks
- Strips must be placed carefully so as not to irritate gums
- Residue may be left on teeth after use
Our Thoughts on Crest Whitening Strips
Crest 3D Whitening Strips is our pick for beginners because they’re very easy to use. The kit comes with strips for your upper teeth and your lower teeth; no extra lights or a serum pen are needed. You simply place the strips on your teeth, avoiding your gums, and then remove them after 45 minutes.
Jared tested Crest 3D White Strips, rating the whitening effectiveness a 4 out of 5. “These strips did a really good job of whitening my teeth,” he said. “You do have to be pretty consistent with them, using them every day to see the best results.”
When it comes to comfort and ease of use, he rated Crest 3D White Strips a 4 out of 5. The upper and lower strips were easy to put on and remove after use.
Our tester didn’t love the film left on his teeth when he took the strips off, however. “There was a noticeable taste to it,” he said. “Thankfully, that residue and taste didn’t stick around for long and were easy enough to rinse away.” Jared rated the taste a 3 out of 5. If you are on a tight schedule, keep in mind that you may have to brush off the sticky residue.
However, if you’re good with a 45-minute routine, Crest strips provide a straightforward, ADA-approved way to whiten your teeth.

Pros
- Easy application
- Lemon flavor differs from typical mint taste
- Strips adhere well
Cons

Our Thoughts on Lumineux Teeth Whitening Strips
Lumineux Teeth Whitening Strips are our pick for the best teeth whitening strips for sensitive teeth because they’re made with a non-peroxide formulation that may be less likely to cause pain or discomfort. Lumineux strips use Dead Sea salt along with coconut and lemon peel oils to whiten your teeth, leaving out any harsh chemicals that could cause sensitivity.
Frank tested Lumineux Teeth Whitening Strips, rating the overall whitening effectiveness a 4.5 out of 5. “As an avid whitening strips user, I was impressed with my first few uses of Lumineux whitening strips. I noticed a big difference in teeth whiteness and brightness by my third use,” he said. “I have very sensitive teeth and only experienced one brief episode of slight sensitivity. The Instructions are very clear and easy to follow, and the strips are easy to apply and use.
“The taste is a very subtle fresh lemon flavor, which is different than usual mint-flavored strips. I really appreciate the clean ingredients in this product and that they do not use peroxide. I feel like this helps with sensitivity,” Frank said, rating the taste a 4 out of 5.
“During use, the strips stuck on my teeth easily and didn’t bother me too much for the recommended 30 minutes of use,” he said. “After using Lumineux strips, there was a slight residue left on my teeth that was easily wiped off. My teeth felt very fresh and clean after use.”
For professionals with sensitive teeth, Lumineux offers a gentle, peroxide-free formula, making it a smart upgrade if you want whiter teeth without worrying about pain during your busy work week.

Best Natural Teeth Whitening Strips Kit: Boca Bella Teeth Whitening Strips
Boca Bella Teeth Whitening Strips
| Fortune score | 4/5 |
at Boca Bella
- Our thoughts: We like the very mild mint taste; it didn’t overwhelm our tester
- Who it’s for: Professionals who prefer to use teeth whitening strips with natural ingredients
- What makes it different: Uses coconut oil, papaya enzymes, and baking soda
Pros
- Flavor is pleasant and not too strong
- Strips stay in place well while wearing
- Flexible wear time (30 to 60 minutes)
Cons
- Very thin strip material can be tricky to handle, per our tester
- May experience leftover strip residue on your teeth
- Upper strip may be too small for your teeth, per our tester
Our Thoughts on Boca Bella Teeth Whitening Strips
Boca Bella Teeth Whitening Strips are our pick for the best natural teeth whitening strips kit because the formulation is made up of coconut oil, papaya and pineapple enzymes, green tea extract, and baking soda.
Courtney tested Boca Bella whitening strips.
When it comes to comfort and ease of use, Courtney rated Boca Bella a 3 out of 5. “The instructions recommend wearing the strips for 30 to 60 minutes. I liked having the flexibility of a longer wear time, but I was curious about the large time range. I wondered if the shorter wear time is recommended for people who experience sensitivity, especially since the product advertises a gentle, no-sensitivity experience,” she said. “I decided to wear the strips for the full 30 minutes. During that time, they stayed in place well and did not slide around.”
Our tester liked that Boca Bella whitening strips don’t have the strong whitening gel taste that many strips have. “Instead, they maintained a mild minty flavor throughout the entire wear time, which became less noticeable as time went on,” she said, rating the taste a 5 out of 5.
After removing the strips, Courtney drank some cold water and noticed that her teeth were slightly sensitive but didn’t feel overly uncomfortable or severe. “I typically have lower sensitivity when using whitening products, and when I do experience sensitivity, it usually goes away fairly quickly. Compared to other whitening strips I have tried, the sensitivity level was manageable and did not last long,” she said.
Overall, our tester liked the fresh mint flavor, easy-to-follow instructions, and comfortable wear experience. “My main concerns were the thin material, which made application more challenging, the upper strip fit, and the difficulty removing the strips and cleaning off the leftover gel afterward. A thicker strip, improved upper strip sizing, and a formula that rinses away more easily would make the overall experience better,” Courtney said. She rated the whitening effectiveness a 4 out of 5.
Boca Bella offers strong whitening with more natural ingredients than some other OTC teeth whitening kits. Keep in mind that you may need extra time to apply, remove, and clean up after use.
Specs:
- Active ingredient: Coconut oil, papaya enzymes, and baking soda
- Whitening method: Strips
- Treatment time: 30 to 60 minutes daily or every other day
Why Teeth Whitening Kits Matter to Professionals
How you feel about your appearance makes a big difference in how you feel about yourself and how you’re perceived. A bright and healthy-looking smile can help you feel more confident when talking in meetings or seeing clients in person.
Many professionals might not have the time to do teeth whitening at their dentist’s office. These at-home kits can provide a more flexible option; that way, you can whiten your teeth when it works best for you. You can also choose a formula that works well with your tooth sensitivity and comfort.
How We Tested and Selected the Best Teeth Whitening Kits
Our team tested six teeth whitening kits, then selected five that we feel are worthy of consideration. Here’s how we tested and selected the best teeth whitening kits.
Effectiveness
Testers took notes on how quickly they noticed their teeth became whiter. Sometimes, this was as soon as two days of testing, while others took longer. Testers rated effectiveness using a score of 1 to 5.
Comfort & Ease of Use
Testers noted how the whitening kit strips, mouthpiece, or pen felt while applying them to their teeth. Most whitening kits are worn daily for anywhere from 20-60 minutes. So, throughout their testing period, the testers noted how comfortable it felt. Testers also considered how easy the whitening kits were to use: did the strips stay on their teeth? Was the mouthpiece/LED light tray comfortable?
Sensitivity
Our testers noted how their teeth felt during the whitening treatment and afterward, paying close attention to any pain or discomfort.
If you’re experiencing reactions to foods or certain drinks (outside of teeth whitening), it may be good to talk with your doctor. See Fortune’s guide to the best food sensitivity tests for more.
Value
When considering the overall value prop, we looked at each whitening kit’s effectiveness, price, duration of use, and most importantly, sensitivity and comfort.
Types of Teeth Whitening Kits
- LED whitening kits (The LEDs are usually built into a mouthpiece where you put the whitening serum)
- Whitening strips
- Whitening trays
- Pens (Brush-on)
- Whitening toothpaste and mouthwash
- Kits that combine several of these products
How to Find the Best Teeth Whitening Kits for You
Here’s what to consider when shopping for the best teeth whitening kits.
Your Whitening Goals
Consider how quickly you’d like to whiten your teeth. Is it for a special event, like a wedding or an important conference presentation? Are your teeth stained from years of drinking coffee? Or are the stains on your teeth milder? This will help you decide on the level of teeth whitening you may need.
Active Ingredients
Hydrogen peroxide or carbamide peroxide are often the active ingredients in OTC teeth whitening kits. Both ingredients may cause sensitivity for some folks; there are also teeth whitening kits that use gentler ingredients like lemon, salt, papaya enzymes, and coconut oil. Consider any tooth sensitivity when choosing the best teeth whitening kit for you.
Fit
Consider whether you want to use an LED mouthpiece, a tray with whitening serum, or a pen to whiten your teeth. Sometimes the mouthpieces or trays are very large and can be too big for people with smaller mouths.
Certifications
The American Dental Association awards its Seal of Acceptance to oral health products. Keep this in mind when considering the best whitening products for you.
Cost
Tooth whitening can be pricey, so consider how much the kit will cost, and if you’d like to buy whitening toothpaste or mouthwash to go along with it.
What to Avoid in Teeth Whitening Kits
Here are a few things to avoid when shopping for a tooth whitening kit:
- Kits that include proprietary blends of whitening ingredients or are not transparently labeled
- Kits with harsh chemicals
- Kits lacking professional organization endorsements (look for the ADA Seal of Acceptance)
Fortune’s Final Thoughts
Some at-home teeth whitening kits can be effective, at least for a little while. At-home whitening typically involves a 20-day commitment, which can be tough to keep up with if you travel frequently or don’t have the time to use the kit every day. If you’ve had dental work previously, it’s best to talk with your dentist about getting professional whitening done to ensure there aren’t any complications with your teeth. In-office whitening done by a professional can be faster (done in one session rather than multiple days), though it may cost more and require an appointment.
Fortune recommends considering teeth whitening kits by looking at the ingredient list/potency, certifications (ADA Seal of Acceptance), and reading reviews about sensitivity and level of effort. Then, you can choose the best option that aligns with your routine and current work schedule.
Frequently asked questions
Should you brush your teeth after using teeth whitening products?
After using teeth whitening products, most dentists recommend waiting at least 60 minutes before brushing your teeth. Talk with your dentist to confirm this before starting a new teeth whitening regimen.
What do professional dentists use to whiten teeth?
In a dentist’s office, professional dentists may use a peroxide gel to whiten your teeth. It may be used along with a light to activate and enhance the bleaching process.
How long does it take for a tooth whitening kit to work?
An at-home OTC tooth whitening kit may take as little as two sessions to show a difference, or up to twenty days or so.
Can I use a tooth whitening kit if I have crowns, veneers, or fillings?
Tooth whitening kits will only work on natural tooth enamel. We recommend talking with your dentist if you have crowns, veneers, or fillings and want to have your teeth whitened.
