If achieving a brighter smile is on your 2026 goals list, you don’t have to spend hundreds at the dentist. The Colgate Optic White Overnight Teeth Whitening Pen, now on sale for $19, offers an effective and convenient at-home solution.
The pen, usually priced at $25, was named the best teeth-whitening pen in a Good Housekeeping Beauty Lab roundup of at-home whiteners. Testing involved 150 participants, who praised its gentle 3% hydrogen peroxide formula, noting it is suitable for sensitive teeth.
A key feature highlighted by testers is the overnight application. “Being able to apply and go to sleep with it on was so easy,” one tester said, emphasizing its convenience for busy schedules.
The pen has also received positive feedback from consumers. Over 2,000 Amazon shoppers purchased it last month, with many noting its ease of use, tasteless formula, and visible results. One reviewer said, “It’s not a super miracle worker, but it does do wonders… My teeth evened out in color and whitened within just a few days.”
Lab testing confirmed the pen can whiten teeth by 1.9 shades in seven days, matching Colgate’s promise of noticeable results within a week. Testers did note, however, that the wand can be difficult to clean.
With its current discount, the Colgate Optic White Overnight Teeth Whitening Pen provides a quick, budget-friendly option for achieving a whiter smile at home.
