Fluoride helps strengthen tooth enamel. Protects teeth from damage by creating compounds with calcium and phosphorus, which are stronger and less soluble than other calcium salts. These compounds remain in the bones and are hardly absorbed into the circulation in case of need for calcium. Children whose mothers during pregnancy consume enough fluoride have less damage to the teeth than children whose mothers had not consumed enough of this nutrient.
Bones are more stable and resistant to degradation if the food has a sufficient amount of fluoride.
