A canal in a tooth is reinforced by forming a lining within the canal. The canal is reamed to a desired size and depth. A light transmitting mandrel is next inserted into the canal and seated in the reamed-out area. A light curable composite is placed around the mandrel. Alternatively, the mandrel is withdrawn, the canal is filled with a light curable composite, and the mandrel is reinserted through the composite into the canal. Thereafter, light is shined on the mandrel to cure the composite. When cured, the mandrel is withdrawn to expose a precise canal in the composite lining.
