Do you understand that sodium fluoride consists from sodium and fluoride? :)
Take some school textbook on chemistry and learn something about halogens, activity and so on.
Fluorine is very active halogen. It can't stay in free form in normal environment. It will replace any other acid base in salts dissolved in water or will immidiately react with anything it touches. So, even if water is fluoridated by passing fluorine gas through it, you will not get a fluorine dissolved in water, but a bunch of fluoride salts - NaF, KF, CaF, MgF from salts like CaCO3, NaCl, MgSO4, whatever you have in water.
So, drinking fluoridated water is in no way different from eating toothpaste with sodium fluoride. :)
Accounting consumption of watever element is done for this element separately, even if it is consumed as salt or some other composition this element part of. So, it does not matter whether you drink fluoridated water, eating sea fish or brush your teeth with toothpaste with sodium fluoride.
