I had my bottom left wisdom tooth (3 8) pulled out last week, it has already started infecting nerves. I was put under local anesthetics, and besides feeling that someone is doing something to my mouth, I didn't feel a thing.
The pain came in afterwards, but I was able to handle it quite well due to the help of 'ibuprofen', a pain relief medicine ingredient freely obtainable at a chemist near you.
I also have to let go of my bottom right wisdom tooth, but since a lot of people, even the two doctors I visited, recommended only getting pulled out one wisdom tooth at a time, since booth teeth are on the same jawbone, and therefore eating becoming quite uncomfortable in the next two, three weeks, I also recommend getting only one wisdom tooth pulled out, as still after one week, eating is quite strange, to write the least. I can't imagine, what it would be like, to have that feeling on both bottom sides.
However it is recommended getting two wisdom teeth being pulled out, when they are on the same side (1 8 and 4 8, or 2 8 and 3 8), as one is still able to use the other side for slight chewing.
I hope it goes well for you, I heard terrible things, but they were not true, for me at least, so good luck and more important, better doctor and assistant to you.
