So let me get this straight...It is NOW the last tooth in your mouth on that side because the original last one was pulled? If there is a tooth on either side of it, it will be ok for now until you decide to get a bridge. If it is the last tooth, it shouldn't interfere with chewing too much, once you get used to it. The top teeth might shift a bit but that takes time, you can get away with it for a while. Dentist need to make money, like the rest of us, and usually will recommend more extensive treatments before just pulling. It's up to you in the end. I had one pulled that was between two teeth, and went for years without a bridge, nothing happened, but then I got the bridge because you could see the hole between the two teeth and it bothered me cosmetically. Sometimes root canals don't even take, and they tooth has to be pulled anyway.
