Hello, several days ago my wife suffered a fall (face first) and had a concussion, bloody lip and some pain to her front teeth area that has since subsided. She went to a local dentist who took an X-ray that was normal. No nerve damage, no injury to the teeth. Despite this, the dentist told her that it was likely that she would lose these teeth, that in the coming months she would see discoloration and would then require a root canal. This seems unusual to me, given the lack of apparent damage. Can you tell me if this sounds right? Thank you.
