What was done
This narrative review synthesized historical evidence from large population studies conducted over 50 years in Nordic countries to evaluate long-term trends in caries levels associated with self-performed toothbrushing with fluoride toothpaste.
What was found
The abstract reports no numerical data or statistical estimates. It reports that regular use of fluoride toothpaste achieved and maintained low caries levels over decades, controlled mineral loss to arrest active caries lesions, and shifted population-wide caries distributions downward across all groups, including disadvantaged populations.
Why it matters
It highlights historical population-level evidence suggesting that widespread use of topical fluoride toothpaste can effectively control caries without relying on community water fluoridation in high-income settings.
Limits
The abstract contains no quantitative metrics, specific study counts, or formal systematic search and synthesis methods. The conclusions reflect observational historical trends in Nordic countries with comprehensive public dental infrastructure, which may not generalize to populations lacking reliable access to fluoride toothpaste.
