While keen focus and a strong work ethic are key ingredients for professional success, a lot of successful professionals might also give some credit to their favorite breakfast beverage: coffee. A little caffeine in the morning helps many folks wake up, but that boost can come with the downside of stained teeth. Not ideal for busy executives who spend a lot of time presenting and putting in face time with employees and partners, when a polished presentation matters.
Teeth whitening has become fairly common, and while it used to take place in a dentist’s office, whitening strips have completely changed the game. They offer a less expensive, at-home option that makes whitening way more convenient, with the bonus that you can do it before or after work—no need to use precious PTO. We took a closer look at a few popular teeth whitening strips and asked our testing team to actually try them out. Here’s what we learned.

Our Thoughts on Lumineux Teeth Whitening Strips
Lumineux Enamel-Safe Whitening Strips are designed to “gently lift surface stains using mineral-rich sea salt and oil-based actives,” according to the company website. Lumineux’s whitening strips are formulated without peroxide, alcohol, and other harsh abrasives, which the company says is a “healthier approach” to whitening because it’s easier on tooth enamel. It also allows for everyday whitening, even for people with sensitive teeth.
To use, apply the upper and lower strips for 30 minutes, then remove and rinse with water or brush your teeth. The instructions say to use the strips for seven days in a row, and then once or twice a week after that for maintenance.
A member of our testing team, Frank—an “avid whitening strips user”—tried Lumineux’s whitening strips and ended up a fan. For starters, he found the Instructions “very clear and easy to follow,” and Frank also said, “The strips are easy to apply and use.”
“During use, the strips stuck on easily and didn’t bother me too much for the recommended 30 minutes of use,” said Frank.
After using the Lumineux strips, Frank noted, “There was a slight residue left on my teeth that was easily wiped off. My teeth felt very fresh and clean after use.” He rated the strips a 4 out of 5 for how they felt on his teeth. Frank also said he has very sensitive teeth, but only experienced “one brief episode of slight sensitivity” while using this product. “I really appreciate the clean ingredients in this product and that they do not use peroxide,” said Frank, adding, “I feel like this helps with sensitivity.”
Our tester also liked the taste, saying, “The taste is a very subtle fresh lemon flavor which is different than usual mint flavored strips.” He rated the product a 3.5 out of 5 for its taste.
“I was impressed with my first few uses of Lumineux whitening strips,” said Frank, explaining, “I noticed a big difference in teeth whiteness and brightness by my third use.” He rated the strips a 4.5 out of 5 for whitening. Seeing visible improvement in just a few days means executives can whiten their teeth on a tight timeline, perfect for a fast touch-up before client meetings or industry events.

- Our thoughts: Our tester found these effective if you use them as instructed
- Who it’s for: Busy professionals looking for maximum teeth brightening without having to spend time at the dentist’s office
- What makes it different: The longer duration—these strips need to be used for 20 days—and longer application time of 45 minutes
Pros
- Effective at whitening teeth
- Strong grip makes it possible to talk and drink water while wearing the strips
- Enamel-safe formula
Cons
- Greater time commitment required (45 minutes per day for 20 days)
- Slightly unpleasant-tasting residue after removal
- Formula not as “natural” as some
Our Thoughts on Crest3D Whitening Strips
Crest 3D Whitestrips Professional White are meant to “whiten like a professional-level teeth whitening treatment,” but in the comfort of your home. These whitening strips have something called “advanced seal technology,” which offers a “no-slip grip” that keeps the strips in place, allowing users to talk and drink water while wearing them. The company also says the formula is safe for tooth enamel, and that the whitening strips “will make your teeth 20 levels whiter” when used as directed.
Instructions are to use one treatment once per day for 45 minutes, and to do that for 20 days. You just peel the strip from the liner, apply the gel side of the strip to your front teeth, and align the straight edge of the strip with your gumline. Then fold the strip over your teeth and press to secure. To remove, peel the strip from one corner and continue pulling it across, then rinse or brush your teeth to remove any remaining gel.
Jared, one of the expert testers on our testing team, used the Crest 3D white strips.
“I recently tested the Crest 3D White Strips, and generally, they did a really good job at whitening my teeth,” he said. He rated these strips a 4 out of 5 for whitening efficacy. While Jared was impressed with the results, he did note, “You have to be pretty consistent with using them every day to actually see the best results.” For professionals accustomed to creating structured routines in order to achieve the best results, though, using whitening strips for nearly three weeks straight may be well worth the time investment.
Jared rated these teeth whitening strips a 4 out of 5 for ease of use, finding them pretty simple and straightforward to apply. However, he added, “One downside was that when I took them off, they left a bit of a film on my teeth that had a noticeable taste to it. Thankfully, that residue (and taste) didn’t stick around for long and was easy enough to rinse away.” Still, for that reason, Jared rated this product a 3 out of 5 for taste.

at Amazon
- Our thoughts: We liked the clear instructions and mild minty flavor
- Who it’s for: Professionals who prefer a gentler formula and familiar mint flavor
- What makes it different: One-week treatment using enamel-safe ingredients
Pros
- Mild minty flavor
- Clear instructions
- Enamel-safe formula
Cons
- Website didn’t list the number of strips and customer service seemed unsure as well; took a while to get an answer
- Difficult to remove the strips
- Gel residue was challenging to rinse off
Our Thoughts on Boca Bella Teeth Whitening Strips
Boca Bella Natural Teeth Whitening Strips claim to “whiten your smile the gentle way,” without harsh bleaching. The company says its formula includes enamel-safe ingredients like coconut oil, papaya enzymes, and baking soda “to gently dissolve tough stains,” and that these whitening strips can leave teeth up to eight shades whiter in just 10 days.
To use these strips, first clean and dry your teeth, then press the strip firmly onto the front of your teeth, beginning with the lower strip. After applying the lower strip, apply the upper strip. Peel off both strips after 30 to 60 minutes and rinse off any remaining gel.
Our tester, Courtney, who says she’s used a wide variety of teeth whitening strips in the past, tested this product.
Courtney first noticed that the instructions were easy to locate and understand, saying, “I especially liked that the first step included a visual guide showing which strip was designed for the upper and lower teeth.”
When applying the strips, said Courtney, “I noticed that the top strip was noticeably thinner and smaller than the bottom strip. I would have preferred a larger top strip because it did not fully cover the area behind my teeth as much as I would have liked.” She also said the strips were thinner than other whitening strips she had used, and because of the thinner material, she had difficulty using these strips as they’d fold or bunch before she could apply them.
Additionally, said Courtney, “Removing the strips was a little more difficult than expected. It was hard to find a good edge or piece of the strip to grip, and once I was able to grab them, I had to pull with more force than I expected because they were strongly stuck to my teeth. After removal, there was a noticeable amount of gel residue left on my teeth, and it was not as easy to rinse away as I would have liked.” She rated the product a 3 out of 5 for ease of use and another 3 for how these whitening strips felt on her teeth. For busy professionals who thrive on schedules and efficiency, the extra effort required to remove the strips and rinse away remaining residue may necessitate an adjustment to their morning or evening routine.
One other thing Courtney liked, though, was that these whitening strips had a “mild minty flavor,” rather than “the strong whitening gel taste that many strips have.” She said the mild minty flavor eventually became less noticeable during the 30 minutes that she wore the whitening strips and rated the taste a 4.5 out of 5.
Specs:
- Ingredients: Papain, bromelain, aloe extract, coconut oil, green tea extract, mint and cinnamon oils, sodium bicarbonate
- Treatment time: 7 days, for 30 to 60 minutes once per day
- Best for: Experienced users who prefer a gentle formula
Why Teeth Whitening Strips Matter to Professionals
Similarly to hair growth serums, teeth whitening strips can help boost confidence and give a more polished appearance—which is important for executives and consultants who frequently present and speak in front of people. And once more, getting professional-looking results without spending time in the dentist’s chair is one of the biggest perks of these kinds of at-home whitening strips. So high performers with packed schedules can get whiter teeth without having to leave work for a dental appointment.
How We Tested and Selected the Best Teeth Whitening Strips
Here are the things we focused on when choosing our top teeth whitening strips.
Effectiveness
We looked for whitening strips that produced noticeable results when used as instructed. While rating efficacy is somewhat subjective—each tester’s teeth don’t necessarily have the same degree of staining, for example—we relied on their reports to find products that seemed to result in whiter teeth.
Comfort & Ease of Use
Whitening strips are applied directly to teeth and left for a certain period of time, which isn’t necessarily the most natural-feeling thing. So we looked for strips that were easy to apply and mostly comfortable to wear for the designated period.
Sensitivity
Applying whitening strips to your teeth and removing them can sometimes result in tooth sensitivity. We looked for products that had a range of formulations and asked testers to report on whether their own teeth were sensitive and whether the whitening strips they tested produced any feelings of tooth sensitivity.
Value
Here’s a cost breakdown of each product, though determining value is subjective. Some people may feel it’s worth paying for certain ingredients, for example, while others may want the teeth whitening strips that offer maximum whitening. Be sure to think about what matters most to you instead of focusing solely on price.
How to Find the Best Teeth Whitening Strips for You
If you’re interested in at-home teeth whitening strips, here are some things to keep in mind.
Whitening Goals
Are you looking for a slightly whiter smile, or significantly whiter teeth? Some strips offer gentle whitening, while others claim to produce a more noticeable result, so choose the product that best fits your goals.
Active Ingredients
Formulas vary, as noted in our lineup. Some products use ingredients marketed as natural or clean, while others might have more synthetic ingredients. If you have a strong preference, keep an eye on ingredient lists to find options that appeal to you.
Cost
We looked at the overall cost of each product, as well as the cost per treatment. Price itself isn’t a great indicator of quality, but we know many people factor it into their purchasing decisions, so we’ve done the math for you.
What to Avoid in Teeth Whitening
While individual preferences vary widely, here are some things to be aware of when shopping for teeth whitening strips.
- Harsh or overly abrasive ingredients can be too strong for tooth enamel. Some ingredients you may want to avoid include high levels of hydrogen peroxide, charcoal powders, and gritty pastes, to name just a few. Instead, look for products marketed as safe on enamel.
- Unrealistic product claims are a red flag. If a company says its teeth whitening strips will remove every stain and result in exceptionally bright teeth, be wary. We also recommend reading online reviews directly on the company’s website before purchasing.
Fortune’s Final Thoughts
Lumineux Enamel-Safe Whitening Strips are made using a gentle formula that suits even sensitive teeth, and our tester saw whiter teeth after just a few days—making this product perfect for busy executives who want a quick smile-brightening before a major presentation.
We also like that these whitening strips can be used once or twice a week on an ongoing basis for maintenance, so professionals can keep up their newly whiter smiles without taking time off work for dental visits.
Frequently asked question
Should you brush your teeth after whitening strips?
We recommend reading the instructions carefully, as each product has slightly different instructions. Some recommend rinsing or brushing, whereas others may recommend only rinsing. Be sure to follow the manufacturer’s instructions for the best results.
Are whitening strips bad for your teeth?
Whitening strips vary widely when it comes to ingredients, and some may use harsh abrasives that could damage tooth enamel. We suggest looking for products with enamel-safe formulations that offer gentle whitening even for sensitive teeth.
How often should I use whitening strips?
Again, we recommend carefully reading and following product instructions to ensure proper usage—including noting the recommended frequency and duration of use. Some whitening strips are designed for shorter-term use, like one week, while others may have a longer usage period, even up to a few weeks. Pay attention to the instructions for whatever product you’re using, as that’s the best approach to ensure safe usage and maximum efficacy.
What should you avoid after using teeth whitening strips?
Make sure to read product instructions before using teeth whitening strips, and note whether the company recommends avoiding any specific substances or activities after use.
