why would you want this? brush your teeth or swish with high concentration fluoride mouthwash. there's actually no benefit of ingesting fluoridated water. any benefit is simply incidental since it must touch your teeth down the hatch. don't take my word for it - go read the papers yourself, they all say as much. Or to put it another way, would pumping fluoride to your stomach help your teeth? I hope you know the answer.
literally every toothpaste in the united states explicitly says to spit, not swallow. there's a reason for that.
