If you are billed for your water by a local water system/district, you can contact your community water district to determine whether your water is fluoridated and the level of fluoride in your water. Check your water district billing statement for the utility's contact information.
Single-family well owners can have their water tested for fluoride at a laboratory; local health districts often have testing capabilities.

“As a doctor, I support community fluoridation because I know that good dental health is connected to overall health. In fact, children with dental disease are more likely to face other serious health problems. In my mind, fluoridation is a no-brainer for the better health of our community.”
