regenerate teeth

The team used high-resolution x-ray imaging and microscopy techniques to assess the formation of reparative (tertiary) dentin 12 weeks after the low-power laser treatment. In the microscopy images shown here, the yellow hashtags (#) sit atop the newly-formed tertiary dentin; there is more tertiary dentin in the laser-treated teeth than in the control.
