Two Canadian friends have invented an entirely new way to brush your teeth – using your tongue.

The tongue2tooth hands-free toothbrush. Coated with toothpaste, it is slipped onto the tongue and used instead of a conventional toothbrush

Adel Elseri and Said Fayad, both 26, say their invention is far more hygienic than a conventional toothbrush.

The disposable gadget, called T2T, which stands for Tongue To Teeth, slips over the tongue, and has a coating of toothpaste.

‘You don’t use your hands, hygiene is key,’ Elseri told the Montreal Gazette.

Elseri, a 26-year-old boilermaker said he was driving home from a 12-hour shift working in Fort mcmurray when he came up with the idea, he said.

The pair have already set up a Facebook page and Twitter account for their invention, and are currently auditioning for the Canadian version of Dragons Den, where they hope to raise $100,000 Canadian dollars to begin production.

The hands-free toothbrush is coated with toothpaste and is designed to be used once then thrown away.

They boast ‘We are the world’s first tongue mounted teeth cleaning product.’
