Dr. Frederick McKay developed the idea of using fluoride to prevent tooth decay.
The idea of using fluoride to prevent tooth decay was significantly developed by Dr. Frederick McKay and Dr. G.V. Black in the early 20th century. They discovered that fluoride was linked to lower rates of dental caries, leading to widespread implementation of water fluoridation starting in the 1940s as a preventive measure for tooth decay. However, fluoride naturally occurs in water, and its dental benefits were observed before formal trials, dating back earlier than McKay's studies.

The idea of using fluoride to prevent tooth decay was developed by Dr. Frederick McKay.
Dr. Frederick McKay, along with Dr. G.V. Black, played a crucial role in researching fluoride's effects on dental health in the early 1900s. Their work led to the understanding that fluoride in water reduced cavities, influencing public health practices. However, fluoride's natural presence and earlier observations by other researchers also contributed.
