Ideally we should all be brushing our teeth after every meal, not just at the beginning and end of the day. But slipping away to brush at work or when we’re away from home isn’t always convenient or practical, so a Japanese company called Yumeshokunin has developed the Misoka toothbrush which they claim only needs to be used once in the morning.
So how do you avoid tooth-rot with such a lackadaisical approach to oral hygiene? Well the tips of the bristles are coated with a specially developed nanomineral coating that serves to make the surface of your teeth hydrophilic after brushing. So the saliva in your mouth tends to stick to your teeth, making it difficult for dirt and other materials to cling to their surface. As a result not only do your teeth stay clean all day, but your mouth as well reducing the bad breath typically associated with a lack of brushing.
