Water fluoridation is a safe, efficient, and well-proven way of preventing dental decay in the community. In countries such as Israel, where dental care is not covered by the national insurance law, this has an important role in reducing social inequalities in health care. For toddlers and children, water fluoridation is the only way of promoting dental health without a need for regular visits to dental clinics, and without regard to parent awareness and motivation. The other methods of fluoride supplementation do not succeed in reaching the level of safety and cost-efficiency of water fluoridation, and their use is successful only among upper socio-economic classes. Water fluoridation has been defined by the US CDC as one of the main achievements in health care during the 20th century. In spite of the legal difficulties raised by various activist groups, the use of water fluoridation is growing steadily among developed as well as third world countries. The Israeli bylaw of national water fluoridation that is in effect will enable the safe improvement of the overall dental health status of the population at an extremely low cost.
