A perfectly white smile determines how others perceive you by shining brightly enough to blind them to your second head and compound eyes. Let dazzling teeth disguise the effects of your mad science hobby with today’s Groupon. For $149 you get a one-hour Kool Lite teeth whitening session (a $700 value) valid at 10 Ontario Altima Dental Centre locations. More than 200,000 patients a year plop into the seats at Altima Dental Centre for dental and cosmetic services dealt by the hands of skilled professionals. The enamel enlightening procedure uses the Kool Lite system, which employs hydrogen peroxide whitening gel in conjunction with the luminous power of a blue UV light to accelerate the whitening process. Incandescent incisors will leave shades whiter without resorting to painful Chiclet implants. A complimentary screening exam is available, ensuring each patient is a proper candidate for the procedure.
