I too hated dentists based on the sadistic asshole dentist that made me suffer as a kid, and I paid for it with a lot of dental work after years of neglect. I am not perfect about dental hygiene by any stretch, but after realizing that not all dentists are named Dr. Mengele, I started going regularly and have had few problems ever since. I still dislike the experience, but routine stuff is far preferable to the alternative. Good luck with your current and future procedures.
