When we hear the word fluoride most of us think about its role in keeping our teeth healthy. It’s true that the main function of fluoride in the body is in the mineralisation of bones and teeth therefore, it is critical for healthy teeth and bones. This is why fluoride is now routinely added to most toothpastes. Fluoride is also present in soils, water supplies, plants and animals. Only a trace of fluoride is found in the body, but even at these tiny amounts, the crystalline deposits of fluoride result in larger and stronger bones and makes teeth more resistant to decay.
