Teeth become discolored after years of drinking coffee and seconds after growling at a squid. Correct discoloration with today’s Groupon: for $149, you get a Zoom! teeth-whitening treatment at Preferred Dental Spa (a $570 value), valid at the Hamilton location.
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 nut-crackers up to eight shades with more efficiency than holding a flashlight between teeth. Zoom! reports that with careful upkeep results can last for years.
For best results, the treatment should be applied within 6 months of a professional cleaning (not included with this offer).
