Check out this new graphic from the Pew Charitable Trusts on the percentage of homes served by fluoridated public water water systems. Public health agencies have long recommended fluoridated water, especially for kids' dental health. In Rhode Island, just 83.9% of homes are served by such treated water.
News also comes today of new recommendations for brushing baby teeth - recommendations that turn the old ones on their head. From the NY Times, the ADA recommends brushing baby teeth as soon as they come up with a bit of fluoride toothpaste (as opposed to waiting until age two).
