Discovery of the benefits of fluoride on teeth: a historical perspective

In the past, people did not know about the benefits of fluoride for teeth. However, various signs appeared in the world, which gradually enlightened the minds of wise men. In remote areas, people who regularly drank water from the same place had white and strong teeth and rarely had cavities. At that time, everyone was surprised and puzzled.

The initial signs changed over time. In modern times, doctors and researchers gradually paid attention to the relationship between water and dental diseases. Some researchers traveled to various places to observe the water quality and the dental conditions of local residents. They found that the water in a certain area contained trace amounts of fluoride, while the incidence of dental diseases among local residents was very low. So they began to suspect that there was some secret hidden between fluoride and dental health.

After in-depth exploration, many researchers came into being and used scientific methods to explore this. They set up experiments, used animals as experimental subjects, fed fluoride-containing substances, and observed the changes in their teeth. People also saw that fluoride made teeth stronger and the incidence of cavities was reduced. However, there were also some problems during this period. If the amount of fluoride is not appropriate, it will be harmful. Researchers painstakingly studied to get the right amount so that fluoride would be both beneficial and harmless to dental health.

As time went on, the researchers' results gradually spread around the world. The medical community knew that fluoride could prevent tooth decay, so it was promoted to the public. First, fluoride was added to drinking water so that the public could enjoy its benefits. People drank water with the right amount of fluoride, and dental diseases gradually decreased. Then, fluoride was added to toothpaste and other tooth cleaners, and fluoride was a weapon to protect teeth. Everyone began to realize that fluoride is a weapon for dental health. Since then, the fluoride tooth care method has been widely spread around the world, working for the dental health of everyone. From the first observation to the present, it has been widely used, which is actually the efforts of scientific researchers and the gospel of human health.
