![]() ![]() How do you use hydrogen peroxide as a teeth whitener? This means if you’re using short, low-concentration treatments, you’ll have to perform more treatments to achieve your desired whiteness. But to achieve the same level of whiteness, one would need to whiten teeth with the 5 percent solution 12 times to get the same level of whitening as one time with the 25 percent solution. This suggests that low-concentration treatments of hydrogen peroxide, applied for shorter periods, have the least potential to damage your teeth.Īccording to a 2004 study, scientists found that a 5 percent hydrogen peroxide solution was just as effective as a 25 percent solution at whitening teeth. They found that higher concentration solutions caused more damage to teeth, as did keeping the teeth in contact with hydrogen peroxide for a longer amount of time. In a 2007 study, scientists applied diluted hydrogen peroxide solutions of 10, 20, and 30 percent to human teeth that had been extracted for varying amounts of time. Concentrations that are too strong can damage the enamel, or outer coating, of your teeth. The amount of hydrogen peroxide in commercial whitening treatments varies and can be as much as 10 percent in some products.īut studies suggest dilution is a good thing when it comes to using hydrogen peroxide for teeth whitening. Here’s what you need to know: Most hydrogen peroxide bottles you can buy at a drugstore or grocery store are diluted to around 3 percent. ![]()
