Q: How Does LED lights brighten your teeth?
A: LED lights are used in teeth whitening procedures because they speed up the chemical reactions that remove the stains from teeth. By speeding up the chemical reactions simply means that more stains can be removed during this time period. Ultimately, the more stains that are removed, the brighter your smile will be. On average, LED teeth whitening can lighten your smile 6-8 shades during a single whitening session.
