I had 6 teeth out on my lower jaw a few weeks ago, and actually I didn't feel too bad, but there was a fair amount of swelling afterwards, and although I'm not working at present, I would not have wanted to go back to work for at least 2 days afterwards, so I would think that you would probably need a week - are you having a general anaesthetic? The main problem I had (which you won't have, if they are removing all your teth) is they had to take out one tooth that was meant to be holding the bottom denture securely, so I've been measured for a new one, but probably won't get it until after Christmas now. I really hope that everything goes well for you, but probably thinking about it is worse than having it done. I also took painkillers before I went in, which seemed to help. One thing you may do is lisp with the new dentures, but once you get dentures worn in, your speech gets used to it. Good luck.
