The history, need and development ofadding fluoride based inorganic compounds in the toothpastefor preventing dental decay is presented in this article. Thefine balance required for maintaining healthy teeth and at thesame time preventing dental and skeletal fluorosis by controllingthe amount of fluoride intake is discussed.
