Go for it!
I know how you feel. I avoided the dentist for ten years because I was too scared / phobic, which led me to have nine cavities and wisdom teeth problems. In the end I was in so much pain that I had to go to a dentist. Like you, I researched dentists in the area speciailisng in nervous patients and found one that does IV sedation.
If you're scared of the exam, please don't be! I was terrified, but the dentist I went to was amazing. To calm me down, I just got to sit in the chair for ten minutes while he chatted about the exam itself, how it works etc. He reassured me I wouldn't feel any pain during the exam and that he was just going to have a look. When I finally did it, wow it went so smoothly! It was nothing!!
He concluded I needed nine fillings and both of my wisdom teeth extracted. My goodness I was TERRIFIED!! I opted for IV sedation as he told me I wouldn't be aware of what was going on and I wouldn't remember a thing.
The big day came two weeks ago. And let me tell you, I was crying my eyes out in the waiting room because I was so scared!! My husband could do nothing to calm me down and I was sure I was heading for the worst pain in my life.
Then the kind nurse came to get me. Sat me in the chair and together with the dentist reassured me I wouldn't feel a thing. In my head, I was thinking that was crap!! How could I possibly not feel anything?? And not be scared??
Then the IV went into the back of my hand (small pinch, no biggie!!). And that was that. Don't remember a thing (even though apparently you're still awake as it is conscious sedation). Woke up in the recovery room with a lovely nurse who said everything went great. Said I was on cloud nine for the whole time and had no idea what was happening.
And now it's done and my teeth are healthy. I'm telling you, it's worth going to get checked out before it gets worse. I was such a phobic, but this has cured me. You realise it really isn't that bad at all. With a good dentist who understand fear, you're in safe hands. I went through exams, nine fillings and two extractions, and I'm sitting here fine. And I didn't feel a thing when they did any of the procedure. Nothing at all. So go for it, you can do it!!
