Fluoride is known to lower IQ in children, cause bone cancer in boys, and induce dental and skeletal fluorosis.  In fact, fluoride can cause more harms than those diseases/conditions.

According to a report released at https://www. researchgate.net, World Health Organization recognizes that fluoride can cause harms listed below:

• Neurological damage

• Reduced IQ scores in children

• Dental and skeletal fluorosis

• Osteosclerosis

• Calcification of tendons and ligaments

• Bone deformities

• Conjunctival hyperaernia (excess blood in the eye)

• Respiratory disorders

• Chronic cough

• Bronchitis

• Chonic Obstructive Pulmonary Disease

• Lung Cancer

• Haematological Disorders

• Nervous conditions

• Hearing and Visual disorders

• Cognitive Decline in older people

• Exacerbation of Asthma

• Diabetes

• Obesity

• Dental Fluorosis

• Cardiovascular disease 

• Cancer

• Osteosarcoma (bone cancer males)

• Thyroid Cancer 

• Osteoporosis 

• Decreased Bone Density
