I am not sure that the pockets that are 4mm. can be eliminated but I think they are maintainable.I certainly would not like to see them get any deeper.Your age comes into play here. The younger you are the more aggressive I would be to try to eliminate these pockets.Your
perioPerio med condition should be closely monitored.
Recently, for some unknown reason, I started to brush(ultarsonic)and FLOSS after EVERY meal or snack. Within a week most of the bleeding stopped. After less than a month, no more bleeding, not even a trace of a pink in the sink. Dentist is amazed at how health my gums are, though not surprised at the results. No matter where he poked, result was the same: No blood! The gums had tightened up and the depth of pockets reduced.
If only I had started this relationship with floss when I was young!
