I recently had some composite veneers top and bottom at the cost of nearly £7000. At first I was pleased with what my dentist had done and they looked great though a week or so later they are already looking stained around edges. Also on one side of my mouth two teeth are already looking quite worn. I have not been given a night guard as yet and was told I'd be given a whiten kit to keep staining down. Am I entitled to have the worn ones redone at the dentist expense?. Thanks
