No Duh!!!

So I'm watching television and there is a commercial where people shopping get their teeth scanned to show the plaque on their teeth, then they get re-scanned and are amazed having fewer plaque in their mouth.

NO DUH -- you just brushed your teeth!

And as far as having a lot of plaque ... how long had it been since you brushed last? I mean actually brushed instead of just popping in a stick of gum.  How long had it been since you ate or drank something?

C'mon!  How stupid do they think people really are?  You have to wonder if the same results would have been seen with any toothpaste ... probably
