I grew up in the US and remember this too, an absolute gag inducing gel that they put in a little mouthguard shaped thing and jammed in your mouth.
There have been various iterations of dentist office flouride treatments I remember.
As an adult the dentists I went to switched to a 2x 30 second rinse (60 second?) with a mouthwash at the end of the appoinment.
The last 10 years they eliminated that and I do a nightly flouride rinse.
I lived various places as a kid, from 10-18 I lived somewhere with no flouride in the water (rural with well water) and we did pills and dentist treatments instead.
Too much in this thread assumes everything is the same everywhere in a given country.
I have also probably never brushed my teeth with a non fluoride toothpaste living in the US. So it's not like that's different from the EU.

I have very little tooth decay in my mid 40s.
