(TOPEKA, Kan.) — It's a question many viewers have shared with us. How does the process of adding fluoride to water work?
We traveled to Topeka, which treats 30 million gallons of water a day. The capital has fluoridated its water for decades.
"Is there a lot of controversy around it here in Topeka?" said Bruce Northrop who runs the Topeka Water Plant. "In the 40 years I've been doing it, there has been very little controversy about adding fluoride to the drinking water."
Topeka dentist Dr. Amy Thompson says the same thing. In her practice, most of her patients don't even know about it - or they simply don't talk about it.
"It's not something you hear about around here." Dr. Thompson told us. "Here in Topeka it's not something you hear a lot about."
