question: I have a traditional bridge. My dentist has told me the rear anchor, tooth number 15, upper left, is decayed and needs a root canal . He s not even sure it will be strong enough for a new bridge. One plan he has is to cut the traditional bridge at the decayed anchor and, in effect, make a cantilever bridge out of the bridge. He will also extract the rear, decayed, tooth. Is this a good plan?
