I'd be lying if I said I'm not confident in my smile. My parents spent good money on years of orthodontic work to get my pearly whites in tip-top shape. And for that, I'm eternally grateful. My smile is one of the things I get complimented on the most, so I'm forever indebted to my parents' good genes and my hardworking orthodontist. Bless up.
However, being the curious beauty editor that I am, I'll never turn down the opportunity to make my smile a little brighter. When the opportunity presented itself to try out laser teeth whitening, I was all in. Like many other beauty treatments that seem cool in my head, I walk blindly into them with minimal information and maximum excitement. According to a recent research report by research firm Arizton, the global teeth whitening industry is expected to reach revenues of more than $6 billion by 2025. In short, the hype surrounding whiter teeth is real and I was all in.
What Is Laser Teeth Whitening?
Laser teeth whitening is an in-office, noninvasive treatment that uses a zoom light and high concentrations of hydrogen peroxide to create a visibly whiter smile.

As soon as I walked into the office of Marc Lowenberg, DDS; Brian Kantor, DDS; and Gregg Lituchy, DDS, I was greeted with a big smile by Lowenberg, who has a star-studded lineup of smiles under his belt, from Chris Rock's to The Rolling Stones' and Russell Simmons's. A few minutes after meeting me, Lowenberg gave me the lowdown on all things laser teeth whitening including the zoom light and high concentrations of hydrogen peroxide that would be used to create my whiter smile.
"The thing about whitening that people don't realize is it does not work on everyone," Lowenberg emphasizes. "The marketing of this industry is so convincing, making everyone feel like they can get whiter teeth. However, lots of the results have to do with the genetic makeup of your teeth. Some people's teeth are dark because they've stained over the years, and others' teeth are dark genetically—just like the color of your eyes. Sometimes you just can't whiten your teeth enough to see an obvious difference. You never know with anyone until you actually do it. You can sit here through the whole process and not see any difference, or sometimes you'll see a great difference—this varies from person to person."
"Some people's teeth are dark because they have internal stains on the tooth, not on the surface," Lowenberg differentiates. "Surface stains come off, but the deeper stains embedded in the enamel are what comes off during in-office treatments when the oxygen molecules from our zoom light are released from hydrogen peroxide, which causes the stains to break up and dilute, which makes the teeth whiter.”
What to Expect
At the start of the procedure, an employee took a mold of my teeth to create a custom tray for my mouth, which I'd need after I left (more on that later). They gave me safety eyewear and set up a contraption inside my mouth to protect my gums from the strength of the hydrogen peroxide. Kantor did the honors for my first lasering session, applying bleach to my teeth and explaining the process.
My teeth were positioned in place, and I didn't move for 15 minutes at a time during each laser session. Kantor checked in on my teeth periodically and applied more bleach after each one to ensure I'd get the best and brightest results possible. Toward the end of my procedure, I started feeling sharp electric shocks. Kantor warned me that these feelings were normal and are signs of my teeth's sensitivity to the high percentage of hydrogen peroxide. The shocks were bearable, just a tad uncomfortable.
Afterward, Kantor and Lowenberg revealed my results, and to say I was happy and thoroughly impressed would be an understatement. I could not stop staring at them. My teeth were shades brighter than what they were before.
At-Home Whitening vs In-Office Whitening
Kantor breaks down the difference between treating teeth stains with at-home versus in-office treatments. "Things like oil-pulling, white strips, whitening toothpastes, and charcoal-based cleaners to whiten your teeth are removing surface stains and making your teeth appear whiter," explains Kantor. "Those products don't actually bleach your teeth like professional teeth whitening. What determines how white your teeth are going to get is how concentrated the hydrogen peroxide is, which is a bleaching agent. With our treatment, the peroxide is remaining isolated on your teeth for a significant period of time."
Hydrogen peroxide is a chemical compound made of H202 that kills germs that cause bad breath, reduces bacteria buildup, acts as a bleaching agent, and diminishes gum inflammation.
"When we're doing it in the office, we're using 35% hydrogen peroxide," says Lowenberg. "When you do it at home, it can be anywhere from 7% to 10%. When you're doing an in-office treatment, there's a much better chance that your teeth will whiten."
Lowenberg recommends coming for an in-office treatment every six months. You can use the at-home, customized tray to whiten your teeth once a month. "The fastest way of bleaching your teeth in-office is by using a zoom light, which activates the hydrogen peroxide and the bleaching gel, which in turn whitens your teeth.” explains Lowenberg. “The way it works is hydrogen peroxide releases oxygen molecules. The molecules are what lifts the intrinsic stains out of your teeth. We use a concentrated amount of 35% of hydrogen peroxide on the teeth. The zoom light acts as a catalyst to release those oxygen molecules so we can break up the stains in the teeth."
It's important to note that one treatment doesn't mean your teeth are eternally white. "The bleaching doesn't last forever," says Lowenberg. "We can whiten your teeth in the office, but eventually, it fades back. In order to maintain it, we make you customized trays that you take home with you. Once your teeth are white, you can do it once a month for a half hour—this will maintain the whiteness."
"Even when teeth whitening does work, the fade-back period varies from person to person," Lowenberg explains. "Some people's teeth get whiter and they stay that way for six months. While for others, their teeth can get dark again a month later. This is why we make the custom trays because I believe no matter how white they get, you have to maintain them or they will fade back."
I was instructed to use my customized tray and apply a lower dosage of peroxide on my teeth for 30 minutes for seven days straight post-procedure to maintain the look of my icy whites. I was also given soothing gel in case I experienced those tingly, shock sensations in my gums again.
But here's the game changer: I couldn't eat any colorful foods or beverages for the next week since they could stain my teeth—a hard task. As a self-proclaimed foodie, colorful foods and beverages fill up my palate. No green juices? Matcha tea? Coffee? Berries? Or hot sauce? I wasn't allowed to eat or drink anything that could potentially stain a white T-shirt.
The reason I had to avoid colorful foods and drinks was because my teeth were extra-sensitive to staining in the next seven days post-procedure. "Right after your teeth are professionally whitened, you can't eat or drink anything with color," Lowenberg told me as my eyes widened. "Don't eat things like spaghetti with marinara sauce, red wine, ketchup, or blueberries. If you're a coffee or tea drinker and you absolutely can't go without it, drink it through a straw. After five days, the new color of your teeth is locked in."
"If your teeth are whitened and you can't fight the urge to drink red wine afterward, you can rub Vaseline on the fronts of your teeth," suggests Lowenberg—it's an old-school trick that works. "The vaseline will act as a barrier so it won't allow the liquids that stain teeth to permeate the teeth. Also, if you're going to drink red wine, coffee, or tea, it is imperative that you immediately drink water afterward so that the residue doesn't sit on your teeth and you're washing it away with water."
This was the hardest part for me. But I stuck to the rules, and I'm glad. I got through it one day at a time.
The Final Takeaway
It's been two weeks since my session, and my teeth are still frosty white. According to the experts, this is the absolute best way to maintain the whitest smile. "The best way to keep your teeth as white as they can be from surface stains is by mixing a fresh batch of Arm & Hammer baking soda powder and liquid hydrogen peroxide. Be sure to mix it to the consistency of toothpaste. If you brush your teeth with that, it'll remove all surface stains.”
