Fluoride is commonly used in dentistry to strengthen enamel& helps to prevent cavities ,large difference in the amount of fluoride found in water supplies.

ACTION OF FLUORIDE: 1-Increase in the enamel’s resistance to acid solubility 2. Remineralization.

3. Antibacterial effects of fluoride.

4. Inhibition of enzymes essential to cell growth of bacteria.
