“After 20 days of daily use in our Beauty Lab, scientists found that these strips whitened teeth two to four shades,” says Beverly Hills-based celebrity dentist Kevin Sands. Lieb is also a fan: “This new version in particular gives a burst of mint flavor to make whitening more enjoyable,” she adds.

One satisfied customer writes: "I was shocked at how much whiter these made my teeth after a couple treatments. I saw immediate results after first session. The overall result is equal to the $100+ treatments I was doing at the dentist's office. Plus this is equal to at least 4 dentist office treatments. And you plug into your phone so you can walk around and do other things and multitask while whitening. Highly recommend!" —Rachel

One satisfied customer writes: "I'm a frequent coffee and tea drinker and regularly use professional whitening kits given by my dentist that involve needles and overnight retainers, and cause a lot of sensitivity.

One satisfied customer writes: "These have a nice thick lining to cover your teeth which stays on the whole time. It doesn’t seep out from behind the layer that holds it in place. The trick to getting even coverage is to push the gel between all the crevices of your teeth and it comes out with amazing results!" —Nicole

I know that I will continue to use it." —katiel339

These gentle whitening strips combine the best of both worlds: a combination of coconut oil and enamel-safe hydrogen peroxide provide noticeable brightening without being too harsh. It includes 20 total treatments (10 for the top, and 10 for the bottom row of teeth), along with three bonus treatments for stain emergencies.

One satisfied customer writes:"I haven’t bleached my teeth for at least three years and they whitened quickly. I used them for seven days without sensitivity and with much whiter teeth. They adhere really well which is a bonus." —Arline K.

When it comes to the natural shade of your teeth, a variety of genetic and lifestyle-based factors can directly impact their color. "Tooth color is a result of both the natural structure of teeth and the presence of stains on teeth. Stains typically come from external sources such as foods, drinks such as tea, coffee, and wine, tobacco use, and tartar," Venda Maloney, senior director of early oral care research at Colgate-Palmolive, explains. "Over time, tooth color becomes darker due to continued exposure to stains as well as enamel wear."

A couple common chemicals used to whiten teeth include carbamide peroxide and hydrogen peroxide, which work in similar ways. Carbamide peroxide lasts longer when its in active form, but needs to be stronger than hydrogen peroxide to work well.

According to experts, whitening can temporarily dry out your teeth, which is ultimately what causes their sensitivity. As the teeth rehydrates, the sensitivity diminishes. "You should always visit a dentist prior to teeth whitening, because whitening in the presence of tooth decay is not advised," continues Lewis. "If you get a clean bill of health from your dentist and you have straight teeth, trying over-the-counter teeth whitening is a great option. If you don’t get the results, you want form those kits you should visit your dentist for stronger concentrations that can be applied safely."

During the whitening process, Lewis notes that one red flag to keep in mind is increased sensitivity that doesn’t diminish after a 48-hour period. "Another is gum irritation, as some people will have increased sensitivity, and will need to take more time in between whitening," he adds.
