Teeth become discolored after years of drinking coffee and seconds after growling at a squid. Correct discoloration with todays Groupon: for $99, you get a Zoom! teeth-whitening treatment at Preferred Dental Spa, valid in Vernon Hills and at four Chicago locations (a $570 value).
At Preferred Dental Spa, tooth whisperers apply a specialty Zoom! gel onto chompers, which then bathe in focused, intense light for three 15-minute cycles. The 45-minute service causes minimal discomfort, if any, and brightens nutcrackers up to eight shades with more efficiency than holding a flashlight between the teeth. Zoom! reports that with careful upkeep, results can last for years.
For best results, the treatment should be applied within six months of a professional cleaning, not included with this offer.
