i have a question about vaneers, and gum problems.

I have severe gum problems on my bottom teeth, the gums have been receeded since i was a young child, i think primary school. I do my best to look after them now but they do get gradually worse each year. the front two teeth also happen to be quite long. I know there isnt much i can do about the gums now other than make sure they dont get worse, however my question is can i get vaneers and not damage them more. My top teeth are overcrowded and my front two teeth in particualar are rather large, with one now overlapping slightly. As the bottom two teeh are also large as well, i can see them looking all that nice just straightened (or if they would even fit!) so i wanted to get vaneers in the hope of reducing the size of my front teeth at the same time. is this somethign that is even possible or that i can have done with damage to my lower gums.

Thanks
