Lost and broken teeth could one day be regrown, scientists believe after finding the stem cells responsible for tooth formation and the gene that switches it on.
Scientists at the University of Plymouth discovered a new group of stem cells which form skeletal tissue and contribute to the making dentin — the hard tissue that surrounds the main body of the tooth. They also showed that a gene called Dlk1 sparks the stem cells into action, so they can mend damage such as decay, crumbling or cracked teeth.
Currently there is nothing to be done to repair damaged teeth apart from fillings or crowns.
