Why is fluoride important for teeth?
Fluoride is often called nature’s cavity fighter and for good reason. Fluoride, a naturally-occurring mineral, helps prevent cavities in children and adults by making the outer surface of your teeth (enamel) more resistant to the acid attacks that cause tooth decay.
Is there fluoride in bottled water?
