Best Teeth Whitening Kits 2022

Amanda Gerla

At-home teeth whitening products offer a convenient and effective way to achieve a brighter smile. Many options can lighten the shade of your teeth as well as a professional treatment could, and often at a fraction of the price. We’ve asked several dentists to break down the best teeth whitening kits on the market. These recommendations often feature active ingredients like hydrogen peroxide or carbamide peroxide to lift stains.

“Hydrogen peroxide is the main ingredient in most tooth-whitening products,” says dentist and If Your Mouth Could Talk author Dr. Kammi Hoss. “Products containing peroxides, such as hydrogen peroxide and carbamide peroxide, act as bleaching agents to change the color of teeth. Peroxide can partially penetrate the layers of teeth, removing compounds that cause discoloration.” According to Hoss, most over-the-counter products feature a range in concentration from 3% to 10%, while dentists typically offer treatments with concentrations up to 40%.

Keep in mind that these aren’t a substitute for routine dental cleanings and exams, but maintaining those can certainly help. “Those who see their dentist regularly, brush twice a day and floss regularly will be able to keep the whitening effect lasting longer,” says cosmetic dentist and Silicon Beach Dental founder Dr. Lawrence Fung. “For some people, the brightness can last a month or two, while for others it may last up to six months.” Ahead, find the best teeth whitening kits for getting a more radiant smile, according to experts.

A Set Of Pre-Filled Trays For Easy Whitening

The Opalescence Go is an easy-to-use system that’s available in various strengths, like 10% hydrogen peroxide, to suit various needs. NYC-based dentist Dr. Sharon Huang finds it perfect for at-home use. “It’s strong enough to be effective, but not too strong that it will make teeth sensitive or cause harm when used as instructed,” she says.

Dr. Fung also prefers this system over other options. “I like the Opalescence Go versus some of the other brands, as their whitening gels not only include hydrogen peroxide but also potassium nitrate, which helps desensitize the teeth,” he says. For best results the trays should be worn for 15-30 minutes daily over the course of 5-7 days.

A Tailor-Made System Delivered To Your Doorstep

This system from Smile Brilliant takes the guesswork out of whitening your teeth. “You take molds of your upper and lower teeth, and the company creates trays that fit your teeth” says Dr. Huang, who considers it as close as it gets to a customizable take-home whitening solution. It comes with a whitening gel made from 22% carbamide peroxide and a syringe for applying the solution to the trays. “If you choose the sensitive option, they will also include desensitizing gel to make the process more pleasant,” she says.

“This kit uses carbamide peroxide, a version of hydrogen peroxide that has a proven track record for whitening,” says Freking. It’s enamel-safe and won’t cause any tooth sensitivity, according to reviewers. The kit should last you four whitening cycles, and when you need a refresh you can repurchase the pen alone, which is great.
