I liked these animated commercials with the Cavity Creeps, Toothopolis and the Crest Force. I know there were others besides this one where the Cavity Creeps would be trying forever to put holes inro the teeth of the gates surrounding Toothopolis but the Crest Force would always be alerted and repel the Creeps by blasting them with Crest toothpaste. That sure seemed to be a good way to encourage youngsters to brush their teeth with this brand of toothpaste.
