I pretty much gave up going to the dentist years ago. When I broke a tooth in 2003 I went to have it fixed, although with the benefit of hindsight what the dentist did merely set it up to break again a couple of years later. So I had it fixed again. When it broke again (early 2009) I just figured I'd leave it alone.
When I had it fixed in 2006 (for the second time) I also had a full checkup and found nothing much had changed in the 14 years since I'd last been to see the dentist. She said I needed a couple of small fillings, and the teeth she filled hadn't given me any grief at all until a week or so after she filled them.
So now I figure I'll keep my teeth in as good order as I can manage but I've become somewhat cynical about dentists.
