I am thinking about getting a couple of veneers to fix a gap between my front teeth. I know this procedure is common, but I'm only 27 so I'm a little afraid of making a commitment that involves filing down my permanent teeth. I've also seen people where you can tell they are wearing veneers because of dark lines above the teeth.
Has anyone had long-term veneers or can offer some advice?
P.S. I'm a worrier, can you tell? :)
