The few cavities that I have had were all extremely tiny and hardly visible to the eye. You won't really know on your own that you have a cavity until it's much more fully developed. At that point, getting it repaired is much more aggravating and a pain. I'd highly recommend getting to the dentist more than once every 6 years.
