Sounds as if I was lucky when I had all my wisdom teeth out then, one side first and then the other a few months later. There was nothing wrong with them except that they were coming in sideways like the proverbial train on platforms one, two, three and four....
Dentist two had to saw one in half to get it out. The reverberations from the saw (tiny circular thing) were weird. Do I mean reverberations? Sure you all get the idea anyhow! That and the amount of force needed to pull them. Fortunately local anaesthetic did work on me and my GP gave me painkillers for when that wore off. It did rather feel as if one had been battered about the head!!
Hope it goes well, cari, and I'm sorry you have to wait so long
