Nearly four million bottles of a Listerine brand mouthwash are off the shelves. It's a product called Agent Cool Blue aimed at helping kids develop good dental hygiene.
Jennifer Barnett has a four year old son and she's a school nurse. She says Listerine's Agent Cool Blue mouthwash helped her son get in a brushing routine.
"He like that it turns his teeth blue and he doesn't mind to brush the blue away," she said.
But now every bottle of Listerine's Agent Cool Blue mouthwash made since the product was launched in 2006 is under recall.
The mouthwash is aimed for kids, with a cartoon character on the label and flavors of Glacier Mint and Bubble Blast. The blue coloring sticks to plaque showing kids where, how long, and how hard to brush their teeth.
"The idea behind it is really good, but if we have a problem with it, it needs to be off the market until it can be corrected," said Dr. R. Lynn Pennington.
The company says preservatives in the rinse do not protect against certain microorganisms. Officials say most children should not get sick, but kids with immunity problems are the most at risk. No specific symptoms have been identified.
"Within 24 to 48 hours, if there are any unusual symptoms, consult with a physician and go from there," Dr. Pennington said.
Barnett says she'll have to monitor her son a little closer without the Agent Cool Blue and he likes it so much, she'll have to secretly take it away.
"This is going to make it a little harder on us moms to get those teeth brushed at night," Barnett said.
But with or without a plaque detecting agent, doctors say that close monitoring is the best way to teach children about healthy teeth.
Information released by the manufacturer states that no other Listerine brands are affected by this recall. For more information on the recall including how you can get a refund on the product, log on to http://www.agentcoolblue.com/
