Researchers from King’s College London have shown that an Alzheimer’s drug can stimulate the stem cells found in tooth pulp and generate a protective material, dentine, in large cavities. The team’s work was published yesterday in Scientific Reports.
If the soft pulp of a tooth becomes infected after a traumatic event, a thin layer of dentine is naturally produced to seal the pulp and protect the tooth from infection. But this layer is not enough to fix large cavities, so dentists use man-made fillings to fill holes in teeth.
