Q. I have recently had root canal work on one tooth and the tooth next to this had been removed due to previous failed root canal work. So far the recent root canal work seems to have worked although I do feel some discomfort from time to time, I am about to have bridgework to rectify the missing tooth. My concerns are what if the root canal work hasn’t worked sufficiently what options am I left with once the bridge is fitted and I’ve paid all this money for a bridge to be fitted over a troublesome tooth would I have to get the bridge and tooth removed. At the moment the gum around the tooth just seems permanently swollen is that normal?? root canal procedure was done twice and almost a month ago now, I suffer from TMJ could this be slowing down the healing process as I’ve notice the temporary crowns I have over my teeth have been ground down?
