IT'S been billed as the biggest event in a generation for people with mouths.
Launched today, Mountain Mouth becomes the world's one billionth dental product and promises a totally new oral hygiene experience.
According to the manufacturers, Mountain Mouth will 'capture the freshness of a mountain and put it in your mouth'.
Henry Brubaker, professor of oral medicine at Colgate University, said: "As a man who talks to dentists a lot, I know they are worried about the lack of mountain freshness in the mouths of their patients.
"We went to the mountainous regions of Tibet, India and China and discovered that those people who still had teeth, had very nice teeth."
He added: "Mountain air can reduce plaque by up to 25% – that's a fact. It reduces the instance of acidic breath by 35% – that's another fact."
Every can of Mountain Mouth will contain fresh, crisp air captured at more than 2000ft above sea level.
People with mouths simply squirt the mountain freshness using the special applicator and instantly feel ready for their next big challenge.
Consumer analyst Tom Logan said: "I honestly felt that a toothbrush for your tongue was as far as oral hygeine could possibly go.
"Now I can't wait to have a mouth full of Mountain Mouth."
