question: About a year ago, I had a root canal on a tooth. Yesterday I went to my dentist because I thought the filling had fallen out. Turns out that the tooth was cracked and split in two. The dentist pulled the loose half out. He suggested a crown but said I had to wait until the area heals. Today, the material from the root canal fell out. I called my dental office and was told that as long as it doesn t hurt, I m okay. I don t know what to do.
