Japanese scientists have created a film that can coat individual teeth to prevent decay
Scientists in Japan have recently produced a microscopically thin film which can make teeth appear whiter and prevent decay! The ‘tooth patch’ is made from an incredibly durable and flexible material which is found in natural tooth enamel which could also mean a solution to sensitive teeth.
The film contains a number of minute holes that allow gas and liquid to escape to prevent the formation of bubbles on the teeth. The film is also transparent but the researchers say it could be made white for cosmetic dentistry.
