Q. I am aged seventy two and I have had upper crowns and bridges for about twenty five years, now two of the teeth are crumbling inter palatally. This involves the left central incisor and the canine tooth. The remedy which has been suggested is to cut of my bridge between the central incisors, have the teeth removed on the upper left and then have implants. Until I get a new bridge I will need to wear dentures, the estimated cost for this is £9k. There will be two dentists involved in this; one says that I must stop smoking and the other dentist say that I do not need to. At present I am hoping that “cosmetic bonding” is an alternative. My questions are. Could “cosmetic bonding” prevent the offending teeth from additional crumbling? If implants are the only solution, will I need to stop smoking? Many thanks.
