Q. I have had 4 porcelain veneers done in Sept 2009 on my front teeth and wish I hadn’t now as have had problems in that after the permanent ones were placed on one came off after 3 days as it appears I grind my teeth at night. I know the veneers are slightly longer that original teeth which i didn’t agree too and so now everytime i talk, they ‘catch’ with the bottom teeth. I am concerened this catching will lead to other falling off prematurely so want them altered so they are same length as original teeth. Will there be damage to underlying teeth if these veneers are taken off to be replaced?
