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

#Ancient observations
In the past, the people did not know the benefits of fluoride on teeth. However, there are various signs in the world, which gradually enlighten the minds of the wise. In remote places, there are people who often drink water from the same place, and their teeth are white and strong, and dental caries are rare. At that time, everyone was surprised and did not understand.

#The first signs
have changed over the years. To the beginning of the recent era, doctors and researchers have gradually paid attention to the relationship between water and dental diseases. Some researchers have traveled to various places to observe the water quality and the dental condition of residents in various places. See that the water of a certain region contains a trace amount of fluoride, and the dental disease rate of its residents is quite low. Then I suspected that there was a hidden mystery between fluoride and dental health.

#After in-depth exploration
, various researchers arose and explored it with scientific methods. Set up experiments, take animals as a test, feed fluoride-containing substances, and observe the changes in their teeth. It is also seen that the tooth is stronger due to fluoride, and the incidence of dental caries is reduced. However, there are also problems during this period. If the amount of fluoride is inappropriate, it will be harmful. Researchers painstakingly study, trying to obtain the appropriate amount, so that fluoride is beneficial but harmless to dental health.

#It is widely recognized that
The years have passed, and the fruits of researchers are gradually spreading in the world. The medical community knows that fluoride can prevent dental caries, so it is promoted to the public. First, add fluoride to drinking water, so that the public can enjoy its benefits. People drink water containing an appropriate amount of fluoride, and dental diseases gradually decrease. Then, toothpaste and other dental cleaners also add fluoride, which is a sharp tool for tooth protection. Everyone began to understand that fluoride is a great tool for tooth health. Since then, the method of fluoride tooth protection has been widely spread all over the world, seeking well-being for the teeth of all people. Since the first observation, it has been widely used so far. It is actually the efforts of researchers, and it is also a blessing for human health.
