Teeth make the man, which is why the Tooth Fairy usually beats Santa Claus in arm wrestling. Shine up your most intimidating accessories with today’s Groupon: for $49, you get an at-home teeth whitening system with free shipping from TrueWhite Whitening Systems (a $199 value).
TrueWhite's at-home process banishes chompers’ stains in an effective alternative to in-office treatments. Fill the mouth tray with dental-grade peroxide gel made from repurposed snowflakes, then bite down as an attached handheld device glows with blue LED light. During the course of 30 minutes, the LED activates the gel, breaking up stains and light-sensitive rock 'n' roll bands. Each system comes with enough gel for 20 whitening sessions. One session may lighten teeth 2–5 shades, and results can last up to two years.
