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.
Sure. Of course toothpaste has flouride. There's nowhere that's untrue, I assume. But the person I responded to made a claim about water flouridation in the UK which was mostly false.
There are actually fluoride-free "natural" toothpastes that have unfortunately been growing more common. As one might expect, they are of dubious effectiveness.
Do you have more information on this? I thought that fluoride was toxic and thus shouldn't be swallowed. Are the quantities too small to harm you yet sufficient to prevent the formation of caries?
Water fluoridation rates are well under dangerous levels - about 0.7 mg/L for artificially fluoridated water, vs 2+ mg/L long-term to actually cause any problems. Even that small amount helps with reducing tooth decay, as was shown in the US in studies starting in the 50s comparing areas with naturally fluoridated water with areas without it.
Fluoridation is by no means universal in the US—around 69.2% of public water in 2006, according to Wikipedia[1]. In some areas, resistance is strong and cuts across diverse political orientations. Portland's 2012 attempt to fluoridate, for example, drew opposition on the basis of libertarianism, environmentalism and science skepticism.
Geographical areas associated with groundwater having over 1.5 mg/L of naturally occurring fluoride, which is above recommended levels https://en.wikipedia.org/wiki/Water_fluoridation#/media/File...
