Millions of people in England receive fluoridated water. This means fluoride has been added to bring it up to around 1mg of fluoride per litre of water, which is a level found to reduce tooth decay levels.
Now I know there is a running joke around the English having bad teeth. But I imagine if millions of people were having issues we’d know about it.
With all of this being said, once you're an adult there's no longer any particularly viable pathways from the bloodstream to your outer teeth, so flouride in the body becomes mostly disconnected from flouride in the teeth (and vice versa). Flouride's effects on the body are less well understood, albeit only because we struggle to measure such apparently small effects on a general population.
That’s why second opinions on important things are vital.
Turns out health professionals are themselves skeptics... (covid showed us already)
Well it's science and at some point, science claimed that earth was flat so...
Good luck again :D
(point is, don't trust blindly)
> Severe : 5 : All enamel surfaces are affected and hypoplasia is so marked that the general form of the tooth may be affected. The major diagnostic sign of this classification is discrete or confluent pitting. Brown stains are widespread and teeth often present a corroded-like appearance.
This is very clearly a conspiracy theory, but water fluoridation is one of those topics that seems to attract them.
If your water is over-fluorinated, you have far bigger problems that stem from your local government.
“These sources include drinking water with fluoride, fluoride toothpaste—especially if swallowed by young children” Ie: swallowing makes it worse but the point of fluoride in toothpaste is to be absorbed, so some will get absolutely even in those who already have issues.

It’s a shame if you mention anything about possible negative effects of fluoride you get lumped in with the crazies.
(just to be clear I am a rational science freak, but my kids have higher priority and we know scientists and corporations have messed up more than once, not going into 'just trust us' with literal poison just because it has good side effects on teeth)
Only at low levels: “Moderate and severe forms of dental fluorosis, which are far less common, cause more extensive enamel changes. In the rare, severe form, pits may form in the teeth.”
He said it happened as he grew up. Wikipedia says almost half of Americans have at least mild fluorisis, there's no need to blame the parents when an environmental/governmental cause is so readily established...
> Also, fluorosis is a cosmetic issue
That's what I thought too but Wikipedia also disagrees on this count:
The pits, bands, and loss of areas of enamel seen in severe fluorosis are the result of damage to the severely hypomineralized, brittle and fragile enamel which occurs after they erupt into the mouth.
Even if that was not the case, you'd need to prove that it's better than hydroxyapatite when applied topically, which (assuming effective) delivery will obviously not be the case.
