re: Are 6 month dental cleanings necessary in this day and age?

What's funny to me is the only time in my life I ever had a cavity was in school when I had no dental insurance and had to pay out of pocket for the procedure from a dentist who was the uncle of someone I knew and was giving me a 'deal'. 1 cavity on my entire life. Part of me still questions if I really had one or if they did the procedure just for the dough.
