Council members had to decide either to fluoridate or put it to a vote. The council decided to put the issue to a vote. And since then, the idea has faced several opposing groups.
Dentist Dr. Sara Meng is among the many Wichita area dentists and doctors who support fluoridation.
"When we see someone who comes into our practice who doesn't have any fillings and are in their early 20s early 30s we can almost guess that they are not from Wichita," Dr. Meng told us.
Dr. Meng believes the dental health of the city would improve with water fluoridation. That's why she joined hundreds of Kansas doctors and dentists to form the group "Wichitans for Healthy Teeth."
"We dedicate our lives to teaching people how to do that and this is the one piece of the puzzle that we are missing," Meng said.
Meng says numerous scientific studies show the benefits of fluoride and reputable health organizations support fluoridation. She hopes Wichita voters agree and vote YES.
"I think we've awoken the silent majority, and I think that is going to help us overcome the vocal minority," Meng said.
At least three groups in Wichita are fighting against fluordiation. Don Landis is with the group Wichitans Opposed to Fluoridation and has worked with another group that opposes fluoridation.
"In terms of why I oppose it," Landis told us, "The number one issue is the freedom of choice."
Opponents like Landis question the benefits of fluoride.
Dr. Paul Connett also questions the benefits. He says the most famous cities in the world are not fluoridating water and Wichita should stay in that league.
"Fluoridation is an arrogant practice" Dr. Connett said. "I define arrogance as ignorance backed up with overconfidence."
Landis believes Wichitans will vote his way, just like they've done several times before.
We've studied it in 1964, we said no, 1978 we said no, the mayor and city council have said no different times throughout the 80s and the 90s," Landis said. "It's come up and it always results in the same thing."
Both sides agree on one thing. They want a lot of voters to cast their ballots on this issue so it shows what the people really want.
