Human: Is it safe to drink water that has a high level of fluoride? Assistant: 
Fluoride is a mineral found in many foods and beverages. It is added to public water supplies to help prevent tooth decay, but too much fluoride can be harmful. The American Dental Association recommends that people should limit their daily intake of fluoride to 0.7 milligrams per day for children and 1.2 milligrams per day for adults. It is important to check with your local water utility before consuming any water from the tap.
