So, does RO remove fluoride? Yes. It removes it with the enthusiasm of a teenager offered free coffee. It’s gone. Vanished. Poof. But – and this is a big, sparkly, toothy but – it also removes other stuff that might be good for you. It’s a water apocalypse, but only for the minerals you didn’t know you loved.
My advice? If you’re not a conspiracy theorist who thinks fluoride is alien brain-control juice, then don’t stress. Drink your RO water, brush with fluoridated toothpaste, and maybe eat some cheese (it’s great for teeth). Life’s too short to overthink your drinking water. Unless it tastes like a sock. Then, definitely get the RO. Just don’t blame me when your dentist gives you the disappointed parent look.
And remember: you can always buy a bottle of fluoridated water from the store and mix it with your pure RO water if you want to create the ultimate custom blend. Be the alchemist you were always meant to be. Just don’t sell it for $12 a bottle. That’s silly. Even for a café conversation.
