impossible to know since i was improving on many fronts. frankly, i think the daily distilled Myrrh dose really did the trick, along with very low sugar intake. but maybe it was the Neem bark? or the cod liver oil? the water pik? the coconut oil. the 5x a day flossing?
from wikipedia:
Peer-reviewed dental literature thoroughly establishes that bleeding on probing is a poor positive predictor of periodontal disease, but conversely lack of bleeding is a very strong negative predictor. The clinical interpretation of this research is that while BOP presence may not indicate periodontal disease, continued absence of BOP is a strong predictor (approximately 98%) of continued periodontal health.[8]
