About 2 years ago I had a root canal done on a molar next to anothe root canal with a temporary crown. I never got a temp crown for the new root canal or a permanent crown. Larry night i noticed clotted blood on the root canal tooth and it was bleeding some. I am in no pain but have a fear of ending up with major issues. I do not have the funds or insurance right now for a crown.... what should my concern be. Obtw i only experience this every once in a while and only while sleep.
