🔬 Medical science
Teeth enable chewing and speech; enamel covers the mineralized dentin around a living pulp. The main diseases are dental caries (driven by Streptococcus mutans and dietary sugar) and periodontitis (bacterial gum infection); enamel erosion relates to acids.
Diagnosis uses examination and X-ray; prevention uses fluoride and reduced sugar.
🧩 The GNM model
Claimed conflict: GNM links tooth and dentin problems to a conflict of "not being able to bite" — wanting to bite back or assert oneself but feeling unable to.
Germ layer & brain relay (GNM model): GNM classes dentin as new mesoderm controlled from the cerebral medulla, while enamel is treated as ectoderm.
Two-phase course (claimed): GNM claims dentin decalcifies during the conflict-active phase and recalcifies/repairs (sometimes with pain) during the healing phase.
⚖️ Critical analysis
Caries is one of the best-understood infectious–dietary diseases; fluoride and reduced sugar demonstrably prevent it, and periodontitis has identifiable bacteria. There is no controlled evidence for a "cannot bite" emotional cause, and untreated dental infection can spread dangerously.
