Not sure why you’re being downvoted. The anecdote happens to parallel the scientific consensus, but “I’m told that dentists can tell” isn’t an appropriate argument when discussing medical research.

The link above is not reputable and was directly refuted by, among others, the American Dental Association, the American Dental Education Association, the American Association for Dental Research, the American Academy of Pediatrics, and the Harvard School of Dental Medicine itself. From the response letter signed by the dean of the HSDM:

The magazine article states that CWF “does not appear to have any benefits in adults” based on the results of the Cochrane systematic review. However, the Cochrane review did not make this conclusion. Rather, the review specifically states “We did not identify any evidence, meeting the review’s inclusion criteria, to determine the effectiveness of water fluoridation for preventing caries in adults.” Due to the lack of studies that met the inclusion criteria, the Cochrane authors were not able to make any conclusion on the effect of CWF on adults. In fact, there are studies that were not included in the Cochrane review that demonstrate a caries preventive benefit of CWF in adults.

See the letter I linked for the studies it’s referencing with a demonstrated benefit to adult teeth. The Cochrane review’s inability to conclude whether there was a benefit or not was a limitation of the Cochrane review’s inclusion criteria, and not an absence of studies indicating a benefit.

The source is not as reputable as it appears. The article in question is not from the Harvard School of Dental Medicine, and in fact was condemned by the HSDM. The actual dental experts at Harvard requested a formal retraction of the article: “Based on the significant flaws in the magazine article, we respectfully request that the article be rescinded, and a correction be published to clarify any misleading information that was provided.”

Thank you for the link. It’s worth mentioning that there are response letters to the publication you linked from other experts, the majority of which are critical and point out misinterpretations and omissions by the author. It’s always good to question, but in this instance it looks like the consensus amongst experts evaluating that publication is still that fluoridation is safe and improves dental health.
