Question about replacing single porcelain veneer?

Okay, so Saturday I am going to the dentist to ***** about my veneers... One of them looks like it is starting to pull away from the gum and my real tooth is slightly exposed (this is the second tooth that has happened to) and my two front teeth, one of them is slightly longer than the other. It looks like one is pushed up higher then the other





Here is the picture: http://aycu14.webshots.com/image/43333/2...





Is there anyway they can fix it? Will they be able to replace them and push it up higher to match the other one? and if so, does anyone know how it would be done. Cause I am really pissed off about the problems I've been having and I've only had my veneers for 3 months..

Question about replacing single porcelain veneer?
This is the part of veneers they do not discuss before hand. Gentle brushing, soft or extra soft toothbrush. They can replace the veneer and make the new one fit close to the gum, but this will not even out the other tooth. They would need to do some crown lengthening/ laser part of the other gum down to match.
Reply:hey stop worrying they will be able to fix them or replace the ones misaligned.by the way i think you have beautiful teeth,may i ask why you got them in the first place?i know there very expensive,i have been looking into them for myself.my hubby has them and hasnt had any problems so far.good luck hon and calm down there fixable for sure.
