After having "OK" teeth most of my life (and I admit to being over 50 now), suddenly for the past couple of years, I've not liked what I've seen in photos.

My teeth are fairly straight, but one top canine, in particular, has drifted back and back and back some more, and the other is sort of trying to hide, too. And suddenly, my two front teeth look a little more 'rabbity' than I'm comfortable with.

On the lower teeth, a space has opened up between two teeth, and it's visible. And my bite just simply feels awful. So, after toying with it, I sought an ortho's advice. Three, actually. The first one wanted to do jaw surgery because he said he could not perfectly fix the malocclusion otherwise. I won't do surgery, partly because of the enormous risk of 'permanent pins and needles' in lip and chin in those over 50. He didn't want to do it by extracting two upper premolars because it would not do good things for my face/profile. So compromise is fix upper stuff (there is enough room) and use, as he said, "lots of rubber bands" to bring the lower teeth forward to a) close the gap and b) compensate for the increased overjet that will happen when those canines get shoved back in line.
What does this mean? I mean, I know what he said. But what is "lots?" I also have a slightly off midline. Perhaps I'll have to buy stock in a South American rubber plantation. (BTW, the second wanted to file down the sides of my already smallish front teeth, not appealing, and the third was pretty much in line with the first....so I am using the first. Spacers on Oct. 17, which makes me think the braces will go on on Halloween. LOL.
Maybe I just need to be calmed down. As it happens, the ortho I chose was the same one my boyfriend's two eldest daughters had (I didn't know that; I didn't tell said boyfriend about it all until I was ready to do it...and he says he's OK with it. The ortho says 24 months plus six total retainers...so I guess that might put a wedding off a bit.....

Any information appreciated.
