A new study has looked at how fluoride in water that you drink when you are a child affects your teeth when you reach middle age.
The study was done by Matthew Neidell and his colleagues and has found that the when you are a child and have added fluoride in your water it will help with dental health much later in adult life.
“Your fluoridation exposure at birth is affecting your tooth loss in your 40s and 50s, regardless of what your fluoridation exposure was like when you were 20 and 30 years old,” said Neidell.
Neidell and his researchers used data from the Centers for Disease Control and Prevention community health study in addition to a water census to look at the impact of drinking fluoridated water in the 1950s and 1960s on tooth loss in the 1990s.
The American Dental Association recommends having public water contain fluoride. There is a lot of history of water fluoridation and opposition. New studies such as this one by Neidell attempt to show scientifically that there is a benefit to water fluoridation.
