Q: I already had a root canal done. Several months later, I had an x-ray done and there was a small gap between my permanent crown and my gum. And whenever I finish eating, I must floss to get the food out between the space, or it feels very uncomfortable. If I leave it alone, what kind of damage would my gum have? I don’t think there is any sign of infection but I’m afraid it would harden my gum.
A: I am not sure exactly what this “gap” is from your description. Is there a gum pocket present? Does the crown have the proper contact and emergence profile? Is there an open contact? Does the floss drop in the space without any contact? It would be useful to see the x-ray, but short of that, maybe have a Periodontist examine you and give you another opinion.
