Is it Good to Drink Water that Contains Fluoride?

by Dr. Joshua Davidson, Senior Dental Care Expert
June 09, 2017

Question: I have heard drinking water with fluoride is good. Is this true and if yes, why?

Answer: Water from planet earth contains fluorides, a naturally occurring substance. In some areas the concentration is quite high and some areas quite low. Foods contain fluoride as well.

When we are young children and forming the enamel of our primary (baby) and permanent teeth the fluoride molecules will mesh with the other minerals (calcium and potassium) to make very strong enamel. If your water contains LOTS of fluoride, then your teeth may have what are called “white spot lesions” – just an abundance of fluoride in your enamel. This is not harmful.

Water containing fluoride can be helpful for growing teeth in that this molecule confers strength to tooth enamel. Here in the US nearly everyone gets a good supply of fluoride from food, water and dental care (fluoride varnish painted on your teeth).
