How stem cells ‘under the spotlight’ could grow new teeth

Studies have revealed that natural tooth restorations are closer than you may have thought.

Special lights and tooth stem cells combined, look set to assign bridges, crowns and fillings to the Museum of Dentistry

The Harvard School of Engineering and Applied Sciences is leading the way in a study of stem cells. The leader of the study is David J Mooney, who is using light to make the tooth stem cells regenerate.

Already, Dentin, the hard tissue that makes up teeth, was easily formed with a low-powered light. In this study rodents were used in the laboratory, drilling holes into the molars, whereby tooth stem cells were inserted and treated with a low light laser. Temporary caps were then used to seal the holes. Just 12 weeks after the study, X-rays revealed that dentin had formed.
