The focal point of a beautiful, confident smile? Sparkling white teeth, of course. And the benefits go even further: Having bright-white teeth can make you look up to five years younger, according to Karen Asp, author of Anti-Aging Hacks: 200+ Ways to Feel-and Look-Younger. But even with the aid of great dental products like water flossers, the best electric toothbrushes and natural toothpaste, daily wear-and-tear to your pearly whites can lead to stubborn surface stains over the years. Luckily, there are at-home teeth whiteners that effectively help erase stains and brighten teeth.
Our top picks:
At-home teeth whitening kits are a more accessible alternative to professional whitening treatments, which can deliver instant and more dramatic results but at a higher price. DIY teeth whiteners can include whitening strips, trays, gels, pens, toothpastes, whitening mouthwashes and LED lights as accelerators, which can provide noticeable effects both immediately and with use over time. "They use various chemical or abrasive agents to lighten or remove stains on your teeth to make them appear whiter," explains Marina Gonchar, DMD, orthodontist and owner of Skin to Smile in Morristown, New Jersey.
To find the best over-the-counter teeth whitening products that really work and rival professional treatments, Good Housekeeping Institute Beauty Lab scientists rigorously evaluate them on consumer testers for factors such as ease of use, sensitivity and lightening of tooth color. Ahead, GH Beauty, Health & Sustainability Lab and dental experts share everything you need to know about the top at-home teeth whitening kits and treatments that are worth it, including options for sensitive teeth.
