I have previously had two replacement crowns in both front teeth from a young age. I later replaced one of them with a screw in crown. I have a problem with grinding my teeth as well. My dentist has suggested I have short teeth and should use a guard but I grind my teeth in the daytime so not sure how this would help? The other and main problem is my screwed in crown is receding due to the grinding apparently. It feels loose and is painful. There is no infection but I would like this replaced and have asked about a bridge, my dentist has said no because it would take to long to heal and I would need my healthy teeth removed. I am confused, do I need to wait until it falls out or can I seek alternative treatments?
