Before we went to Dr. Young, my son had no cavities. He fill a few cavities that our previous dentist said were small and didn't need to be filled. He did such a poor job that 3 years later, when we returned to our first dentist, the teeth had rotten at the roots and he had to get root canals. We had only changed dentists because we moved here from Canada. Now my son returns to Canada to see our previous dentist.
