#1 Opalescence Go – Prefilled Teeth Whitening Trays Kit
Opalascence Go Prefilled Trays wins our pick for best teeth whitening trays. A whitening tray can offer a happy medium between white strips and an LED device, typically with a more comfortable and sometimes more effective output. The Opalescence Go Prefilled Trays use a 15% hydrogen peroxide treatment, which is higher than some of the other options on our list, meaning you’ll get faster results.
We noticed almost immediate results after one use, although the higher dose causes some discomfort and sensitivity. We tried the higher formulation, but Opalescence also makes its trays in a 10% hydrogen peroxide formulation.
Opalescence is also a favorite brand of dentists, particularly Dr. Velayo. “More clinical studies, articles, and reviews have been published on Opalescence whitening than any other professional whitening brand. It’s part of the reason why it’s so highly trusted,” she says.
#2 Crest 3D Whitestrips Professional Effects Teeth Whitening Strips Kit
True to its claim of professional-level whitening, these Crest Whitestrips are the GH Beauty Lab’s gold standard for smile brightening. Lab evaluations found that after 20 days of daily use, they lightened teeth a noticeable two to four shades. The strips simply stick on teeth and can be worn during daily activities for convenience. (Note that they must applied for 45 minutes to achieve best results and some reviewers experienced discomfort during use.)
They are touted by dental professionals, too: “These strips are the most effective at-home teeth whitening product,” says Michael J. Wei, DDS, FIADFE, a cosmetic dentist in New York City. “They are designed to remove tough stains from coffee, tea and smoking, and they’re easy to use, since they don’t require any special trays or gels.” Ellen Katz, DDS, Co-Founder of Maison BE Dental Studio in New York City, also recommends this kit and Dr. Gonchar calls it “one of my personal favorite over-the-counter whitening products.”
#3 Snow Advanced Wireless Teeth Whitening Kit
No pesky cords attached to this innovative Snow LED teeth whitening kit, which has a wireless LED mouthpiece to use with the included hydrogen peroxide gel. In GH Beauty Lab testing, it received a perfect score for not sensitizing teeth or gums, was easy to use and brightened teeth by one shade after one week of use for the recommended nine minutes per day.
Though one tester found the LED device uncomfortable in the beginning, another liked the “durable” silicone mouthpiece and that she could “walk around and do things while using it.” It earned raves for being painless: “This is the easiest and most painless whitening kit I’ve used,” a fan said.
#4 Crest Whitening Emulsions Leave-on Teeth Whitening Kit
An easy-to-use Crest teeth whitening gel with a spatula applicator, this delivers real lightening effects in a single day, no rinsing necessary. (Some users commented that it didn’t adhere to their teeth well, however.) “It painlessly whitened my sensitive teeth about two shades over one day — the difference is noticeable,” marveled GH Beauty Lab Senior Chemist Sabina Wizemann. “It stayed put, and after a minute or two, I didn’t even feel it on.”
#5 Colgate Optic White Overnight Teeth Whitening Pen
If you’re looking for a portable teeth whitening option, many brands offer whitening pens filled with a gel formula of whitening ingredients like hydrogen peroxide or carbamide peroxide. To use a whitening pen, you brush the gel on your teeth and repeat as directed.
Colgate Optic White’s White Express Teeth Whitening Pen contains hydrogen peroxide and comes with enough gel for 35 treatments. The pen has a narrow applicator brush, whitening treatment can help whiten your teeth more than two shades in three days when used as directed, according to Colgate. However, to achieve the best results, be sure to follow the seven-day plan detailed on the whitening pen’s packaging.
#6 SmileDirectClub Teeth Whitening Kit
If you’d rather use a rechargeable, wireless whitening light, SmileDirectClub’s kit comes with a battery-powered tray that has built-in LED lights to help activate the included whitening gel. You also get a charging case for the tray, plus a travel cover. One charge lasts one full week of treatments, according to the brand.
SmileDirectClub’s kit includes a gel pen filled with a hydrogen peroxide-based whitening formula, which you brush onto your teeth before inserting the LED light into your mouth. Treatments last five minutes – the light beeps and turns off to alert you when you’re done. The brand recommends using the teeth whitening kit twice a day for the best results.
