Nope—it’s called fluoridated toothpaste or fluoridated mouthwash.
Which is only ten times more expensive. It’s also more effective than just drinking fluoridated water, as you might expect, so the comparison isn’t that clean.
Hopefully you’re buying toothpaste anyway, so the relevant number is the difference in price between fluoridated toothpaste and non-fluoridated. I think it’s more or less zero. In fact, non-fluoridated toothpaste is likely to be some all-natural all-organic fancy expensive thing :-)
