Know this is an old thread, but, yes, I've had Botox and fillers. I didn't much like them, though. I agree with the view that it can be preventative too, as it freezes the muscles, presumably stopping the skin wrinkling up. I do face exercises now, which are free and non-invasive.
I think the reason why older women (and men)! ?? can look odd with Botox is that it smooths out one part of the face only whilst not addressing the general sagging effect an older face has. So, even if you have good skin, if your face has sagged with age you look older anyway.
pompa it's possible to have teeth corrected as an adult but quite expensive, I gather.
