Tooth Whitening Goes to Masses
Jim Valentine,founded WhiteSmileUSA with two fellow entrepreneurs in February 2007, describes the company as "one of the pioneers in this new industry segment" -- a segment that could generate $3 billion in sales this year.
WhiteSmileUSA now operates in 22 states. Soon, its technicians are expected to start working at some Wal-Mart locations, moving the company one step closer to its goal: "to bring professional-grade teeth whitening to the masses."
People who work in the kiosks generally aren't dentists or even dental hygienists, they're legally prohibited from working inside customers' mouths. As a result, they merely help prepare the mouthpieces, or trays, that contain the whitening agents and then hand them to the customers, who insert them.
Dentists typically charge $350 to $1,000 for teeth-whitening treatments in their offices. At-home kits provided by dentists usually cost $250 to $350.
Recently, at the Sam's Club on Sawmill Road, WhiteSmileUSA was offering a "double application" for $143.27. A "complete" package, which featured the double application as well as an "aftercare kit," was going for $173.15.
WhiteSmileUSA has served more than 30,000 customers, and none of them, he said, has encountered any problem other than teeth sensitivity and gum irritation, temporary side effects spelled out in the company's consent form. This is what company spokesman said when Dentists protested against such practice as being unethical.
Some states have filed suits and have ordered such kiosks to shut down, MORE HERE
