I would go 4 or 5 years without seeing the dentist because of my phobia. I remember the days of no novacaine and the pain. I have sensitive teeth where a cleaning can sent a few jolts of pain through me. Lucklily I have found a hygenist that is excellent and she doesn't chide me if I go a little longer than I should between cleanings -- I always hated the lectures, that would keep me away even longer.
As I get older I realize how important it is to keep my natural teeth as long as I can. Most of my fillings are older and I have had some teeth break and go through having caps done. It's expensive but worth it.
That reminds me, I need to make an appointment for a cleaning!
