In October Listerine launched a new digital campaign, 'Mouth Off', aiming to raise awareness of all the things people put their mouths through.

The Listerine Mouth Off depicts the 'ultimate rap battle' that takes place between the mouth's worst enemies to determine who really is the 'baddest' for the mouth.

The six rappers battling it out for the title include some of the freshest UK rap talent such as Pen'alty – strong flow writer, weak gum biter; Miss Tea – the queen of stains; and Sir Rap'Shallot – a rap superstar with big beats but bad breath.

The host of the show, MC Total Care, announces the winner which is then followed by the ultimate 'beat-down rap', proving his seniority over any of the wannabe contenders because when it comes to mouths, nothing is 'bad enough' to beat Listerine Total Care.

For the first time, Listerine also has a presence on Twitter, where the @ListerineUKMouthOff handle will allow fans to follow and interact with these outspoken chins.
