I'll preface my response to this by saying that I've never been very consistent about taking care of my teeth. So, most things I've had done at one point in time or another over the course of my life.

I had an abscess that was excruciating. Anti-biotics sometimes help. Otherwise, they have to get in there and drain the infection, either by drilling the tooth or removing it if it can't be saved. Awful experience. If the abscess is bad enough, anesthetic won't always work. Anything beyond that that I've ever had, regular OTC pain killers usually do the trick.
What's a root canal feel like?
The answer to this is the same as the answer to most dental procedures. Depends on the dentist. If they know their stuff and properly administer the anesthetic before hand, I don't find them to be significantly worse than any other procedure other than the time required to do them. If also depends on whether or not they are killing all the nerves or just one of them. If they are killing just one, the tooth can be quite sensitive for a while afterward. Oherwise, there is no nerve left so there shouldn't really be any pain to deal with after the fact. Your jaw may hurt like heck, though, from being pried open that long, depending on where it is.
The tooth may or may not require a crown afterward, depending on how much of it they destroy in the process. With a full root canal, the tooth may eventually have to be pulled, but I have not yet had that problem on the couple I've had done.
Are dentures worth it?
In general, I'd say yes. If you're missing all of your teeth, you obviously need to ask yourself how much of a headache do you want to go through to eat tough foods.
I'll qualify this by saying that my mother has dentures. I have a bridge. So, there is a bit of a difference there. I have always been of the opinion that the human mouth is designed to have a certain number of teeth. You can get away with having one or two on the ends pulled, but if you start pulling teeth in the middle you're going to eventually have issues. May take a few years but missing teeth will likely cause the surrounding teeth to loosen. At least, that's been the case with those I've known, anyway. Everybody is different, I suppose.
Implants are another option that alleviate some of the headaches of dentures. A lot more expensive, though. I don't know anybody who has them to really comment on them beyond that.
I was just talking to a friend of mine and she's in some really bad dental pain and I was thinking that I don't know what it feels like.
I've never had a cavity, a root canal or a filling. I take really good care of my teeth and I see the dentist 6 times a year

Like I said, I don't take the best care of mine. In contrast, though, my mother took great care of her teeth. Brushed all the time and still ended up having every tooth in her mouth pulled as they became infected at the roots. There are some people who, unfortunately, have dental problems no matter how well they take care of them.
Other than that, I'd just say... 6 times a year? Sheesh.
