Hi Jason, thanks again for all the information you continue to provide and help. I am hunting down a cerec dentist here, attempting to find one that does not charge too much for the, plus reduces the cost if he's doing many at once. I have found "one", and the cost is lower than any of the others, but I am still going to contact others in case I can get an even better deal. Doesn't mean I'm going for it though, but it's good to "shop around".

I am keen on cerec, but I still get jittery about the metals, even if they are in the oxide form, because it does seem porcelain has much more in them, but again they seem more stable so..... and perhaps they do not have all the other things composites do. Hard to tell.

I asked a holistic doctor on a website for dental issues,questions etc and asked him about both dental materials heliomolar and cerec and he informed me that both of them were "ok". So I don't know, hearing so many things it's hard to know what to believe.

But the fact that Cerec lasts for so long also, and the fact as far as I know it is very hard for any plaque to form around it and it can rebuild teeth in a sense also (this I need, because two of my teeth are very suspect).

Jason, do yourself a favour, request a local anaesthetic WITHOUT a vaso-constrictor. Vaso-constrictors in local anaesthetic are designed to reduce/prevent blood flow to the area, which makes the numbing last longer etc etc.

They are finding out slowly but surely (well some dentists), that this can be a prime cause of cavitations in the jawbone, plus can risk tooth death, simply because the blood flow is removed for an extended period of time. I wonder if this is what happened to me, because a doctor detected gangrene in my mouth, dead pulp as he called it. Could have been wisdom tooth removal though, but could have been the anaesthetic bringing the cavitation on, or a deadening of the area itself, allowing a kind of rotting to stay there.

So my advice to you is, request the non vaso-constrictor local anaesthetic. THey can also cause heart palpitations as well. I remember I had one done and the oral surgeon could not get me numb (interesting considering it's supposed to numb more effectively than other local anaesthetics) and he injected me over an dover again and I was close to passing out. I had to sit up, my heart was pounding and racing and I was terrified, he was too. My pupils were apparetnly dilated. It was like having masses amounts of adrenaline pumping through. He still could not get me numb properly and I was in some pain.

So, so much for it's effectiveness. Who knows what that may have done to me and my gums.

and don't take any vitamin C on the day, or in fact the day before you get dental work done. You may know this already, but in case you don't, it can eraze the effects of the anesthetic and you will be in pain. Better not to take vitamin C for a few days beforehand to be even safer. Fine to resume immediately afterwards of course.

Keep us posted Jason. when are you going through with the dental job by the way? I'll be very interested to hear how it goes.
