That pesky wisdom tooth you're glad you got rid of is apparently a great source of stem cells that could save lives. However, it's not easy getting to the tooth root pulp that contains those cells: drilling into the tooth generates damaging heat that lowers the number of cells that can be harvested. In addition, the water used to rinse the tooth could have corrosive elements and the enamel particulates from the drilling could contaminate the pulp.
