Im sure with all the latest dentistry techniques available these days, your discomfort could be kept to a minimum, i do hope so, there is always intravenous sedation, works very well, with some procedures ,and laser dentistry which is considered to be painless, whether its done for wisdom teeth, im not sure, but check out all options before you go ahead,and dont be too scared, no surgical procedure is pleasant, but im certain things wont be near as bad as youve been hearing, times have changed and things are usually much better these days , heres hoping.
