Lying through their teeth.

Have you had gingivitis? Do you know someone who has? According to this Crest commercial one in two people gets gingivitis so you should know dozens of people who are suffering from or been treated for gingivitis. But I doubt that you do. I think this is an outrageous exaggeration and I can't imagine why Crest thinks anyone will believe it. Making such a statement brings into question all their other claims for fewer cavities, whiter teeth, better checkups. There was a time when there were watchdogs to protect consumers from these kind of absurd claims. But it seems that truth in advertising has gone by the wayside. Pity.
