Practicing lawyer Mark Rossman replaced his name on the lawsuit with that of Leslie McQuillan from Saginaw, Michigan, according to an Associated Press report.
Rossman’s law partner Gerard Mantese told the news service that Rossman did not want to be too closely linked to the story.
Lawsuit has generated further complaints
However, Mantese did state that since the story about the lawsuit was broken by the US media, their law practice has heard of ‘dozens’ of other users of the mouthwash who claim to have experienced similar problems.
Rossman said his wife alerted him to the stains and after doing some internet research he discovered that the same complaint had already been made by a number of other consumers, an Associated Press report said.
P&G has not responded directly to the lawsuit, although it did say that '99.9 'of product users had not complained, and even ventured to claim that the tooth stains might be a sign the product is working.
'Violation' of consumer protection act
Rossman has filed a class-action lawsuit against the company in Michigan, claiming that P&G is violating the state consumer protection act.
In a related incident last October, Johnson & Johnson (J&J) re-released a tinting mouthwash a year after the product was pulled from the shelves when testing uncovered contaminates.
Listerine Agent Cool Blue is a mouthwash that colors the teeth blue to encourage children to pay more attention when brushing but the product returned to the labs for reformulation in April last year.
