About 8 years ago I had a root canal procedure, less than a week later the tooth broke off at the gum line, next i went through a very painful tooth extraction followed by not one but two crowns to anchor the now necessary bridge. About two months ago i had to have another root canal on one of the teeth anchoring the bridge. yesterday while haveing Christmas Dinner my whole bridge/partial broke off. Question, how long should these last? The teeth in question are my two front teeth and the one to the right side of my mouth. secondly would implants be the best way to cure this problem?
