When I went to him as a new patient, Dr. King started off by telling me that I should consider having my teeth whitened. Then he told me that I had half a dozen cavities. Since I've had only one filling in my entire life, I questioned this assessment. I went to another dentist for a second opinion, and sure enough, he detected no cavities at all. Now this may simply be a difference of opinion, but my sense was that Dr. King was eager to sell me whatever products he could.
