Hope I can help a little...
First off, it's not like we're in the early days of medicine anymore. General anesthetic is considered to be safe, and the people that give it are highly trained professionals who watch you carefully through out the proceddure to make sure that your okay. If I understand it right (I'm a social worker, not a nurse!) the anestheseologist actually stays with you through out the process and monitors your vital signs. I know for some proceedures, you actually meet this person in advance and they walk you through what to expect. It is considered to be safe.
Now as far as wisdom teeth go, mine weren't impacted as badly as yours are, but i had all three out at once... under local anesthetic without sedation. I couldn't understand why they kept pushing sedation on me.... I think they were just used to dealing with people so out of it that they didn't need a bedside manner! I could have chosen general, but i didn't like the idea of being knocked out... Sometimes you can choose it, other times you have to go general. Given your fears, I'd suggest you call the dental office and tell them you have a lot of fear and some questions. See if someone can meet with you to discuss the proceedure more- especially if a blow by blow would helpyou. Or maaybe they can connect you with someone who's gone through it... doesn't hurt to ask. Given your fear, if it can be done by local with some strong sedation, that might be better for you. That's just really strong pain medication and something fairly strong to keep you relaxed and happy. Your actually awake, but not at all with it. However, if you choose to be awake, I'd suggest music and headphones- the sound effects are nasty!!
Mine went off without a hitch, although one of my adult teeth needed a filling, and afterwards I had dry sockets... Once the packing is done, it will feel like there is still something in the whole- that's the clot and it needs to stay there. If it actually feels empty, go in because you could have a dry socket, and for most people that is exceedingly painful. Oh, and don't be a stubborn #%#@ like i was, make sure you take the pain meds the give you, when your supposed to. No matter how well you handle pain, you don't want the freezing to come out before the pills kick in. I was really concerned about narcotics... but it really is important to take what they give you for the pain.
It sounds like you have a problem with fear... Just tell it to leave you alone. Stand in your faith. IT WiLL be OKAY. This is really a safe proceedure...
I'm going in for gall stones soon, and that is a little un nervy for me- I'll actually have to be put out. Never had that before. But I'm not sure i want them cutting into my stomach while I'm awake, either!
Do you have any allergies to medications? If so, just make sure they know about it. The only time things get complicated (to my understanding) is when you have an alergy to the medications. Which is why there's an anethestist watching you, and they take very good care of you. Is yours at the dental clinic or at the hospital? If it's at the clinic, then rest confident their not expecting complications. If they are, they book you into the hospital and do it there so that they everything at their finger tips if needed. Their not allowed to take chances with your life, so rest at ease. Even in the clinics they have everything they could need. They are skilled practioners of their work. Rest at ease.... it WILL be okay. So, if your booked into the clinic, then you have absolutely NO grounds to be concerned for your life. But make sure you talk to them about any medication reactions you've ever had!
This fear... Have you had fears like this before? Is it common for you to react fearfully, or are you more of a gut instinct kind? If you truely beleive this is just a irrational fear, then just push past it. But if you've had alot of gut instinct reactions... weigh this out and see which it is... and if seems like it could be a gut instinct, then talk to your doctors. Then at least they'll be extra prepared in case there is something unusual. Normally, these procedures are routine. But some people's bodies do react differently to things sometimes. Take an objective third person view of your fear. Where is it coming from? What is bothering you so much? Have you just heard horror stories? Is this just a fear of the unknown? Or is there something to this? Is it a gut instinct. or God trying to tell you that this may not be wise? Weigh it out as best you can.
Let me knwo when it is, and we'll be praying!
