Chuck typically concluded his lecture about my father’s miserable dental habits by shaking his head dejectedly and admonishing me: “What a waste, David! Don’t let it happen to you. Be wiser and have those checkups.” Not that I had a choice. Dental misbehavior was not an option for a youngster with Uncle Chuck in the family. He saw to it that I was in his office every few months. I dreaded those visits and could understand why my father had forgone them, whatever the consequences.
