I had a root canal work recently on my upper front tooth and the nerve was removed. My doctor did not insert a post saying that it would require a crown as a consequence and that it would change the apppearance of the tooth (it will change color, etc). He also said that this is an overall complicated procedure in my case. At the same time, he said that this tooth has a tendency to rotate over time. Also, the tooth without a post is fragile and my doctor said that I need to take a good care of it.
Now I don't know what to do -- I don't want to loose my tooth over time, and on the other hand I don't want my tooth to loose appearance.
So, my question is how dangerous is it to be without that post for upper front tooth?
Thank you very much!
