Introduction: Dental fluorosis remains one of the commonest disorders affecting the teeth, starting right from the early age. Hence the importance of preventing dental fluorosis is at the school age level. To a certain extent (as per WHO; 0.6 ppm) fluoride ingestion is useful for bone and teeth development, but excessive ingestion causes a disease known as Fluorosis.The greatest concern in dental fluorosis is aesthetic changes in the permanent dentition (the adult teeth). These changes are prone to occur in children who are excessively exposed to fluoride between 20 and 30 months of age. The critical period of exposure is between 1 and 4 years old, and the child is no longer at risk after 8 years of age. The severity of dental fluorosis depends on the amount of fluoride exposure, the age of the child, individual response, and weight, degree of physical activity, nutrition, and bone growth.
