Fear appeals, individuals' cognitive-behavioral responses, and willingness to pay for safe water in fluoride-contaminated regions.

In rural areas with high fluoride concentrations in groundwater, affordable and effective de-fluoridation technologies can significantly reduce the likelihood of being affected by fluorosis-related illnesses, such as skeletal fluorosis. This is particularly significant in areas where groundwater is the primary or sole drinking water source, such as the Rift Valley of Tanzania. Despite the availability of technologies, people's use of de-fluoridation devices still needs to be improved.
