Lasers have been used to regenerate parts of damaged teeth and could one day be used to prevent root canal treatments, claim US researchers.
The laser beam triggered a series of changes that led to the formation of new dentin, the layer below the enamel, in animal tests.
The results, in Science Translational Medicine, showed stem cells in the dental pulp were activated.
Experts said it was intriguing, but a long way from the dentist's chair.
The team at Harvard University used a drill to remove part of a tooth in mice and rats.
One dose of laser therapy on the damaged tooth led to the production of a partial layer of dentin 12 weeks later.
