Systematic review of cessation of water fluoridation (2016)
A recent systematic review of the dental health effects of cessation of water fluoridation (1) has concluded that “overall, the published research points more to an increase in dental caries post-CWF cessation than otherwise”.
The review analysed data from 15 instances of CWF cessation in 13 countries, which covered a broad time frame (1956 to 2003) and diverse geographical and political/economic contexts.
BFS has made the author aware of an important early UK study which was not included in the review (2), but would likely further strengthen this conclusion.
