Q. Hello, I have a question. I have had a marilyn bridge (between my canine and front incisor) since I was about 13 due to a congenital missing upper left incisor. Over the years my marilyn bridge has decemented (and subsequently fallen out) about every five years. About 5 years ago I tried to have an implant put in, but that surgery failed (and subsequently I lost most of my bone where the implant tried to take hold). My bridge feels loose again, but last time it was cemented in my dentist mentioned that I’m loosing a lot of enamel due to the sandblasting/adhering agents put on the back of my teeth. Is there something else I can try? I really don’t want to go through the bone regrafting and implant process again due to cost; but I’m worried about what will happen if I have to keep recementing the bridge back in… is there anyway to repair the enamel? Or another technique I could try? Thanks so much in advance for your advice.
