I had composite veneers done twice, the first time they had deteriorated so had them redone but I didn't like the shape & colour. I now have porcelain veneers I feel like they based them off the second composite over my teeth not my tooth under. They feel big, don't match my other teeth and feel like they are a mouth guard just stuck there or a beak. The dentist said it's because I have an over jet and need Invisalign but it is the thickness of them. My original teeth are quite small and flat.
