I have dental insurance a DMO through Delta Dental but I'm so lax in going to routine checkups. However, I do try to floss and rince with listerine every day and brush a lot. Haven't had any cavities or major dental problems so far!
My dentist charges $50.00 for a checkup/cleaning. My dental insurance premium is about $100.00 a year and that covers my whole family (4). So I definately come out ahead since we each do 2 cleanings a year -- $400 in cleanings only cost me $100 in premium. Not to mention my son recently started the braces saga.
