Scientists discover way to 'grow' tooth enamel
Though enamel is the hardest tissue in the body, it cannot self-repair. Now scientists have discovered a method by which its complex structure can be reproduced and the enamel essentially "grown" back. The team behind the research say the materials are cheap and can be prepared on a large scale. "After intensive discussion with dentists, we believe that this new method can be widely used in future," said Dr Zhaoming Liu, co-author of the research from Zhejiang University in China.
