Two Canadian friends have invented an entirely new way to brush your teeth - using your tongue.
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.
They boast, "We are the world's first tongue mounted teeth cleaning product."
