That's about water fluoridation. Not about the direct gel treatments we get which contain very strong fluorine. Which are done on the post-childhood teeth. We get them like 4 times, every 6 months for 2 years for about 5 minutes. They're very strict about not swallowing it because it's toxic and the smell made me nauseous.
As far as I've heard they really improve enamel strength a lot. My dentist used to joke it put them out of business.
