Q. I am on my 5th set of veneers. I have the top front four teeth veneered. I started with NHS but they kept chipping and falling off. My dentist then talked meinto private veneers and I am still having problems with then chipping and cracking. Last night my front veneer chipped again and looks awful. My dentist has not charged me for replacing up until now and I guess he wont believe it when he get’s my call first thing Monday morning. Is it time to replace the veneers with crowns?,
