The oral health coordinator for the Fond du Lac County Health Department says they have a program for children in rural areas who don’t have the cavity-fighting protection of fluoride in their water. Samantha Twohig says there’s a program they do in the rural schools. She says they oversee the fluoride mouth rinse program that is a weekly mouth rinse that the kids do. She says fluoride is added to municipal drinking water and it’s a benefit that Fond du Lac and North Fond du Lac offers. Fluoride has been a hot button issue in the Fond du Lac area in the past, but Twohig says that’s died down a bit. She says it’s a naturally occurring substance that is in every source of water, but it varies by location.
