The gingival sulcus is another niche held by neutrophils; once a keystone pathogen turns the guard, leaked inflammation becomes food — the same class of loop as a gut community feeding on inflammation.

Heart
Severe periodontitis and cardiovascular disease are independently associated; candidate mechanisms are bacteraemia plus systemic inflammation, not a dirty mouth wrecking the heart.

Lymphatic System
What leaks from the sulcus into blood is bacteria and fragments; the lymphatic island is transport, not flushing bacteria out of the groove. Detox massage is not on this chain.

牙龈沟是一个生态位

Stop 1/4

The sulcus is a niche

The shallow groove between tooth and gum is normally held by neutrophils and complement, with a mixed community doing its jobs. Once the groove deepens, oxygen falls and anaerobes have a place to live. This island is not simply whether you brushed. It is who pries that groove open.

Hajishengallis 2015 turns the old model over: periodontitis is not a few classic periopathogens acting alone. It is a community in which different members play different roles that converge to feed destructive inflammation. The fluoride island covers enamel mineral. This island covers the soft tissue in front of the periodontal ligament and the bone.
