Agent Cool Blue: "Does It Work?"--UPDATE-PRODUCT RECALLED



Parents, there's a new secret weapon out there to help you get your kids to brush their teeth. Chances are, if you can get them to brush at all, you still have trouble getting them to brush long enough to do any good. But what if they could see the plaque and have fun brushing it away? That's why the folks at Listerine came up with something called Agent Cool Blue. Kids will love the way it's marketed. But before you fork over the money, we'll put it to the "Does It Work?" test.

Here's the idea. Tint otherwise invisible plaque with this bubble gum flavored blue dye. Then have fun brushing. Just rinse for thirty seconds. Spit it out and look for the blue marks on your teeth. Tyler dentist, Dennis Stansbury tested it for us on his own teeth. "All I can see is just a tiny bit (of blue) between his teeth," says Dental Hygienist, Cadey Gillert.

So how do we prove or disprove Listerine's claims? What if Dr. Stansbury has not plaque on his teeth?

Remember those small red tablets they gave us as kids? They still exist today. They're called disclosure tablets. They're really nothing but vegetable dye. They should show us if Cool Blue Missed anything.

Dr. Stansbury chews one up. Swish and spit. "Oh yeah. See, look at that," says Gillert.

Dr. Stansbury had red dye all over his teeth, especially along the gum line and between teeth. We had the exact result, except more convincing, with a dental assistant. What Cool Blue missed, the red tablets found.

"The Cool Blue, although it has merit, is still inferior to the traditional disclosing tablet. As we saw, the disclosing tablets show more than the Cool Blue shows," says Dr. Stansbury.

So, Does it work? "I would say no," says Stansbury.

 And the Hygienist? "I would say for someone who has extremely heavy plaque it might show some results. But the standard patient with minimal plaque with there, it doesn't disclose the plaque like it's supposed to," says Gillert.

"Does It Work?" They give Agent Cool Blue a "no."

We paid $4.50 for a 500 ml bottle of Agent Cool Blue. You can order those little red disclosing tablets online. They run about ten cents a piece...and they work!
