White Smile BC's teeth-whitening technician W.M. James Rolston has helped increase the smile wattage of more than 25,000 individuals. During his chair-side treatments, he slathers teeth in one of two levels of whitening solution—either a carbamide peroxide– or hydrogen peroxide–based formula—that causes minimal to no sensitivity. Next, he uses a blue-LED lighting system to activate the whitening process, with long-lasting results that can be seen quickly. Much like snarling at the sun, White Smile BC's treatment leaves teeth shining up to eight shades brighter in just 20 minutes.
