In adults

The short version: the retrieved studies do not directly test whether mold damages adult teeth, and the adult evidence for mold harm is mostly respiratory, not dental.

The records here focus on mold and breathing problems. One large Nordic study of about 11,500 adults found dampness and mold at home or work raised the odds of new asthma, wheeze, and cough [2]. A separate review found limited and inconsistent evidence that mold causes adult asthma in the general population, with the strongest adult link only in occupational settings [1]. Another review judged the evidence as association, not causation, for respiratory and allergic outcomes [3]. None of these records measure tooth decay, enamel defects, or gum disease in adults.

The indirect pathway from your earlier question, infection-driven enamel damage, applies mainly to children whose teeth are still forming. Adult teeth are already mineralized, so that mechanism largely drops away. What the records do show for adults is chronic airway inflammation from mold [1, 2, 3], which could plausibly affect oral health through systemic inflammation, but no retrieved study tests that link. The retrieval also surfaced several unrelated records on nail fungus, aflatoxin, and dental restorative materials; they do not bear on this question.

The honest gap: no retrieved study compares dental outcomes in mold-exposed versus unexposed adults. The mechanism is plausible but unproven.

My call: the evidence does not establish that mold damages adult teeth; it supports respiratory harm only. Confidence: low.
