The research I read says that Americans are accepting Community Water Fluoridation in droves
The latest data show that in 2014, 74.7% of the U.S. population on community water systems, or a total of 214.2 million people, had access to optimally fluoridated water. This is continued progress from the Healthy People 2020 baseline of 72.4% (2008) towards the target of 79.6%. Since 2008, nearly 19 million more people have received the benefit of fluoridated water.  Evidence shows that the prevalence of tooth decay is substantially lower in communities with water fluoridation.
