My dentist promised a 7 year warranty on my veneers. After paying for my veneers and having my teeth shaved down (yet the veneers not installed yet), I was given a piece of paper stating they have a warranty on crowns (no where in paperwork does it mention veneers) as well as there is a 5 year (Not 7) percentage structure that they will decreasingly cover repairs/replacements for. He up sold me from clear braces to this (2500 to 4200) I want my money back if no warranty...
