Why is too much Fluoride in water a problem?

Our bodies need certain amounts of Fluoride for strong bone formation. However and like everything in life, too much of anything is poisonous. According to KEBS and WHO standards for drinking water, the maximum fluoride limit acceptable for human consumption is 1.5mg/l. Consuming water that has Fluoride above this limit will result in bone deformation. This is because the Fluoride in the water attaches to the Calcium in the bones therefore altering their properties and making them brittle (easy to break). When this happens, it is evidenced by the browning of teeth of the affected person. This may sometimes affect the self esteem of the person thus limiting their life potential.
