Fluoride-containing dental care products (mainly fluoride toothpaste) vs Dietary fluoride sources (drinking water, beverages, food): Contribution of dental care products to total daily fluoride intake (TDFI), by tap-water fluoride level
In adults in poor-fluoridated tap water areas, dental care products contributed on average 12% of total fluoride exposure (ungraded; 1-2 studies).

Studies behind the findings
None of these reviews ties its included studies to this outcome in the data here. Cochrane reviews and reviews with headline outcomes only do not list their studies yet.
How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
