question: I recently had a root call retreatment on #14 and had a crown replaced after. The tooth was asymptomatic prior to the retreatment, but had what appeared to be a periapical radiolucency on the mesial root. Several months later, I now have a fairly deep periodontal pocket on the mesiolingual surface despite having an excellent hygiene routine: I floss 1-2X a day, brush 2-3 times a day, and my last prophylactic cleaning was in June.  Is there anything I can do to help this pocket outside of seeing a periodontist?  It isn't painful, but can be a food trap and it is sometime malodorous when flossing.
