From plain english Cochrane:
Data suggest that the introduction of water fluoridation resulted in a 35% reduction in decayed, missing or filled baby teeth and a 26% reduction in decayed, missing or filled permanent teeth. It also increased the percentage of children with no decay by 15%. Although these results indicate that water fluoridation is effective at reducing levels of tooth decay in children's baby and permanent teeth, the applicability of the results to current lifestyles is unclear because the majority of the studies were conducted before fluoride toothpastes and the other preventative meaures were widely used in many communities around the world.
There was insufficient information available to find out whether the introduction of a water fluoridation programme changed existing differences in tooth decay across socioeconomic groups.
There was insufficient information available to understand the effect of stopping water fluoridation programmes on tooth decay.
No studies met the review’s inclusion criteria that investigated the effectiveness of water fluoridation for preventing tooth decay in adults, rather than children.

Thats not what the Newsweek article said.
shame the "journalist"' did not read the entire Cochrane review and was clearly not a native speaker as he "misinterpreted" insufficient evidence for "fluoridation is shite"
As for the Cochrane Review, the stringent inclusion/exclusion criteria eliminated 97% of all research articles.
The reality is that the efficacy of fluoridation is less than it was when first introduced as there are many more sources of fluoride today. Foodstuffs made with fluoridated water plus toothpaste, varnishes and the like have increased the bioavailability of fluoride in non-fluoridated communities.
This debate has and always will be primarily a political one.
