You should watch this video about fluoride and oral health. Fluoride in toothpaste is one thing. You can buy a toothpaste with or without fluoride if you wish so however in the case of water supply you do not have a choice. You are down to a water company. Alternatively you can buy bottled water but then does it make sense to pay twice for water? And/or invest in an expensive filtration system and hope it removes the toxins?
By the way you also want to check the labels on bottled water as unfortunately most contain fluoride as it is bottled from fluoridated source.

Fluoride
You may think that this is not a big of a deal because the big heads must have work it out precisely and ~1mg of fluoride in 1 litre of water should not be a problem, right?

So now imagine 1 litre of water from Severn Trent Water that has been adulterated with 6mg of Hexafluorosilicic Acid to achieve 1mg of fluoride in 1 litre of water.

Now look at this:

This is a 22kg bag of sodium fluoride that is added to drinking water by some water companies in United States to make the teeth of Americans healthy. Can you spot anything worrying on the packaging?

So now imagine that Hexafluorosilicic Acid is much worse because rather than sodium fluoride STW adds the acid but to achieve 1mg of fluoride they have to add 6mg of it so every 1 litre of water you drink or you bathe in has 1mg of fluoride but also 5mg of other harmful industrial waste in it like lead, arsenic, cadmium and nickel.

If it happens that you live in a fluoridated area you drink at least 4 litres of liquids a day. In this case just by drinking tea or coffee with that water you expose your body to about 3-4mg of fluoride a day!

If you didn’t know your skin is very absorbent. I let you work out how much fluoride your body absorbs through skin from bath water and from fluoridated steam you breath during shower.

Remember Hexafluorosilicic Acid is a byproduct of fertiliser production. It’s a toxic waste product that is scraped off chimney filters then sold and shipped to STW and other willing water companies in the world to add it to water.

Fluoride is used in:
1. rat poison (1,3-Difluoro-2-propanol, Fluoroacetamide, Sodium fluoroacetate)
2. drugs like Fluoxetine (Prozac, Trifluoromethyl) to numb the mental patients
3. deadliest of chemical weapons Sarin (Propan-2-yl methylphosphonofluoridate)
You bet fluoride is a necessary ingredient of any poison!
Why? Because fluoride makes it potent, reactive. It binds easily to other molecules.

Why they do that?
The initial problem was that the heavy industry primarily aluminium and fertiliser production had to do something about toxic waste including fluoride they produced. Before any oversight was in place they just dumped it into the rivers but once the public/government oversight was in place they had to go about the problem in a different way.
Imagine loads of commercial recyclable waste that is not profitable to be recycled here in UK so it is shipped to poor countries e.g. to Africa so the Africans sieve through these large piles of rubbish e.g. electronics.
It’s a common practice to find someone either willing (corrupt) or unaware of the danger. In this case they devised a plan to make toxic fluoride look good to your health and force it onto unsuspecting public.

The same is to do with industrial waste. The corporations cannot just dump it into the ocean so they must find other ways to dispose of it.

Remember this fluoride phenomenon is as old as the case of DDT when some scientists and health professionals were confident enough to spray DDT. powder on people including little children to prevent diseases from lice.

How do you think this worked out for these people?

I save you time to read that Wikipedia page. Long story short it turned out DDT is a carcinogen = cancer.

Here is a video where Bryan Johnson talks about heavy metals in chocolate.

He is providing you the laboratory figures for heavy metals in micro grams (μg) not milligrams (mg). Heavy metals are toxic even in tiny amounts.
The worst chocolate in the competition had 10μg of heavy metals in it.
Now fasten your seat belts.
Severn Trent Water puts on average 1mg of fluoride in one litre of water which is 1000μg what is 100 times more but do not forget about the other industrial waste which makes it 6000μg in total in just one litre of water so 600 times more than the worst chocolate on the market.
Can you see the difference or do you need some time to wipe your eyes?
How much chocolate do you consume and how much water do you drink a week?

Now let’s look into the bathroom how much water we use. Standard UK bath tub can hold up to 300 litres of water. Let’s say you take a bath and you fill it in half that makes it 150 litres of water what each time exposes you to ~150mg of fluoride and 5x more of heavy metals.
10 minute shower is about 120 litres of water what again makes it ~120mg of fluoride and 5x that of heavy metals.
In both cases your body absorbs it through skin and through breathing steam.
