The AcceleDent—which was recently approved by the FDA and should be available in the US by the end of January—looks like a mouthguard but with a vibrating apparatus hanging off the end. When used for twenty minutes each day it's been found to increase tooth movement up to 106 percent in the initial phase of braces treatment, and up to 38 to 50 percent as the teeth get closer to their proper alignment.


Unfortunately the amount of time you use the AcceleDent doesn't directly correlate to how sooner you can get your braces off. It's been found to be most effective with the recommended twenty minute per day treatment, while prolonged use can actually hinder its effectiveness. So cranking it to eleven and sleeping with it strapped to your face will actually do more harm than good. [AcceleDent via CNET]
