Interesting Fact - Health
Scientists in Japan have created a microscopically thin film that can coat individual teeth to prevent decay or to make them appear whiter.
(Don't get too excited though. It will take 5 years or more before the film could be used in practical dental treatment such as covering exposed dentin, but it could be used cosmetically within three years. If it means I don't need to have my teeth sand-blasted every year, I'm all for it.)
