### Human:\nmy city water has fluoride in it. is drinking that enough for my kids or do they need more?\n\n### Assistant: if you go to your municipality's web site you can check on the fluoride levels. as a science-based organization the ada supports the department of health and human services' recommendation to set the level for optimally fluoridated water at 0. 7 parts per million. this adjustment will provide an effective level of fluoride to reduce the incidence of tooth decay while minimizing the rate of fluorosis in the general population.
