Hi rom - I went to the dentist last year after nineteen years' absence! I had a massive pain and there was nothing else I could do. I ended up having a root canal filling, and have gone from being one of the most terrified people ever of dentists, to making my own appointment next month for my checkup! One tip would be, don't get there too early, try and get there at the exact time of your appointment so you're not sitting for ages in the waiting room wondering what's going to happen, and what the hell that noise is! Good luck!
