A week or so ago, I posted a little snippet about advances in dental filling material that promise longer-lived fillings. But what if we could get teeth to repair themselves?

Almost all human tissue can regenerate to some degree. Even dentin, the mineralised material under the enamel, can grown back a little if it is exposed. But the enamel itself? No way. Or so it was thought. But it seems some Chinese scientists may have cracked the problem. As you can read, they have managed to recreate the unique and complex structure of enamel within a cavity. As the researchers say, turning this laboratory work into a clinical treatment is a long-ish road, but I’ll be keeping my eye on it!
