You can't scroll through Instagram without seeing a million celebrities endorsing LED light teeth whiteners, but believe it or not it's more than clever marketing. "LED lights work well to whiten teeth because they speed up the bleaching process and catalyze the release of oxygen molecules that break up the stains on the teeth and make them whiter," Lowenberg says.
When you purchase an LED light teeth-whitening kit, it will include the LED light, a mouth tray and whitening gel. Once you have placed the whitening gel into the mouth tray and applied it to your teeth, you'll sit for the next 30-60 minutes while the LED light works its magic and speeds up the gel's bleaching process. "The peroxide [a major teeth-whitening ingredient], is activated by the power light, and causes the oxygen molecules to penetrate the enamel surface and break down the dark stains within the inner tooth structure," Lowenberg says. While the at-home LED light treatments are not as strong as in-office treatments (Lowenberg says in-office treatments contain 35 percent hydrogen peroxide while over-the-counter typically contain seven to 10 percent), with consistent use (on average about a week), this at-home teeth whitening technique still gives you noticeable results.
