Oral surgeon took pan full mouth x ray, and commented about about dark area around root of molar recently crowned. Recommended followup with regular dentist due to appearance of infection there.
New dentist took another x ray and recommended root canal. Dark area was still there, but to me didn't look as dark as in first X ray. I do not have any symptoms from this that are bothering me. I have since had professional cleaning, and am scheduled for 2nd cleaning visit and other work as needed.
QUESTION: Is there any chance that this "infection" will improve with better cleaning and daily oral rinsing or other care?
Is a root canal warranted based on the description above?
