Yes, there cases where crowns and bridges have lasted many years. However, there are too many outside factors that influence the longevity. Is the patient complient with his home care? Does he see his dentist on a routine basis? If their diet is high in acidic foods or beverages the incidence of deay is greater. What if they are a bruxer or ice chewer the porcelain can fracture.There are just too many things that are beyond the dentist's control to guarantee his work if the patent is not doing their part.

Therfore, I am against such an action by the Board.
