The reason fluoridation is not more widespread is the opinion held by some that adding a "medication" or other substance is the thin end of the wedge for some folks in that it infringes their personal liberties.
It is the fear that any future government of the day can add other substances to the populations' water supply to suit the government public policy of the day.

Regarding the British public dental health, we have free dental health care until 18 years old, including oral hygeine lessons in primary school.
The reason for private health tourism to countries you mention is not only the rise of Fear of missing out and keeping up with the likes of the CarCrashians and their ilk but lack of dental hygiene a cause of tooth decay.
Im in my sixties and I have every single one of my teeth as does my husband and my offspring.
I forgot to mention I also provide toothpaste and floss for my guests too as well as sanitary towels and tampons as standard along with linens etc.
I am not interested in the race to the bottom regarding hosting standards or price or the cut price cheapskate values that accompany this mentality.
