I'm sceptical of this source. The post claims fluoride in toothpaste (which isn't even ingested!) is a neurotoxin and refers to a review which I cannot find (https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=lanc... doesn't come up with much, closest I got were https://www.thelancet.com/journals/laneur/article/PIIS1474-4... and follow-up https://www.thelancet.com/journals/laneur/article/PIIS1474-4..., neither of which discuss fluoride toxicity in toothpaste). I think we should take this author's claims with a generous helping of salt.

With that said, I wouldn't eat the stuff, but this post goes a lot further than that.

In the US, drinking water supplemented with fluoride for this very reason, so feel free to rinse out your dislodged food scraps after brushing and ignore this advice from the NHS.

In the United States, recommended fluoride levels in drinking water are 0.7ppm, whereas toothpaste is 1000ppm - 1500ppm.

So even with fluoridated water you want to avoid rinsing.

Also from the article: " It's best to floss before brushing your teeth. "

Why? I would have thought it makes more sense to brush, then floss, then wash at the end so the fluoride stays longer

I always thought that flossing mostly moves the dirt from between your tooth to another side. So I always brush after flossing.

(I also never thought about fluoride so of course I rinse after brushing and I will continue to do so because otherwise it would be very uncomfortable)

This is dangerous advice. Fluoridated toothpaste is incredibly important for the health of your mouth. The source you've provided is highly suspect, and the claims contradict mountains of evidence of fluoride's safety.

Enough flouride to cause long-term health issues takes at least 2 mg/liter of water (probably more) over a long period of time, while artificially fluoridated water standards are 0.7 mg/liter. Even many rivers and lakes have a natural fluoride content of 0.3 mg/liter.

While there is risk from fluoridated water in some places, generally this is from unusally high natural fluoridation, from minerals leached from rock exposed by volcanic shifts or badly-regulated mining.

I looked into one of the references...they put 120mg/L in mice and found it to be bad. Drinking water has about 0.7 mg/L. This is a factor of nearly 200x on concentration and another lot on body mass. Shoot, if I drink 200x more water that will cause problems too!

Concentrations matter.

Earlier quoted context omitted.

Have you ever brushed your teeth?? (Just joking)

I think we all use excessive amount of toothpaste. That makes us get a mouth full of foam, that subsequently forces us to rinse instead of just spit.

Great marketing by Colgate. They just show the toothpaste covering the entire length of the brush and we all follow along.

As far as I know a function of flossing is to disrupt bacteria in places that your brush can't reach.

Presumably another is to dislodge food stuck there.

I can imagine that floss + rinse would accomplish both well enough, especially if it's twice a day (but surely most people brush one a day)
