My dentist has prescribed me Duraphat 5000 (5x normal fluoride content). He said that I should:
1) Brush my teeth with my usual toothpaste.
2) rinse with water
3) apply a small amount of Duraphat on my teeth and rub.
4) don't rinse afterwards.
However, at the back of the Duraphat box, I read:
"Do not swallow!"
Forgive me I'm wrong, but if you don't rinse, you're going to have some toothpaste circulating in your mount and, at one point, you are going to swallow it. Or am I missing something?
Is the dentist giving me wrong advice? It seems this advice is quite common here in UK:

It's a matter of degree. I knew Duraphat as a fluoride varnish. I see
it now comes as a toothpaste, 5000 ppm. As such, it appears to
Prevident 5000, which I prescribe in my practice. The instructions are
however to BRUSH with it for 2 minutes, and spit out (not rinsing). The
idea is to thoroughly expose tooth surfaces and leave a residue that
will increase resistance to decay. Right off the top of my head, it
seems you'd get better penetration by brushing, but I don't know this
for a fact. Also, rubbing on teeth and not rinsing would seem to leave
more fluoride in the mouth.
In your linked article, there is no mention of a high-fluoride gel or
paste. In the U.S., these are available only by prescription. Most
fluoride toothpastes deliver 0.1% fluoride (1000 ppm.) So your
high-fluoride paste is 5 times as concentrated.
I would be inclined to urge caution--if you're going to do this, use a
very small amount to rub into your teeth.
