Pam Yelick, G89, a professor of orthodontics and director of the division of craniofacial and molecular genetics, and her colleagues are developing ways to grow healthy new teeth and bone from dental stem cells—a type of “universal cell” that can morph into many different types of oral tissue. After harvesting the stem cells from healthy adult tooth pulp, Yelick’s team isolates them in the lab and gradually coaxes them into forming new tooth buds, the tiny clusters of soft tissue that eventually grow into a mature tooth.
Scientists in the UK have developed a new material that can be inserted into teeth to repair and regenerate dentin - the hard, bone-like tissue that makes up the bulk of all teeth.
Just like regular fillings, which are inserted into a tooth to block off spaces where bacteria could colonise, the new material is injected into the tooth and hardened with UV light. But once inside the pulp of the tooth, it actually encourages stem cells to proliferate and grow into dentin.
"We have designed synthetic biomaterials that can be used similarly to dental fillings but can be placed in direct contact with pulp tissue to stimulate the native stem cell population for repair and regeneration of pulp tissue and the surrounding dentin," says lead researcher Adam Celiz, a therapeutic biomaterials researcher from the University of Nottingham.
As mentioned earlier, the team hasn’t released a lot of information about their new material, and have yet to publish it in a peer-reviewed journal, so we’ll have to be cautiously optimistic about it for now until we can see more information about exactly how it works, and how expensive it will be.

well Thank god. Hopefully this works. I and my medical insurance company seem to pay and pay and pay. No matter how well i take care of my teeth.
