Or I'm going to give up and not use any. Consumers aren't perfectly rational. This isn't like toothpaste, where, despite being overwhelmed at the store, I still need to brush my teeth so ahhhhhh fuckit and just pick a toothpaste out of the 30 available. The alternative is I keep using Google search and think AI is stupid. Or just use Facebook's thing.
The frontier toothpaste is the one with bioglass 45S5. Especially if you have sensitive teeth or your teeth are prone to caries.
Nano-HAp is good, too
The irony with tooth paste is that out of those 30, probably 28 are exactly identical. If all you want is fluoride tooth paste then pick the cheapest tooth paste.
If you want to go optimize your mouth hygiene it is actually more important to use dental bristles (flossing is not as good), because most of the work is done by the mechanical cleaning action of the tooth brush and you need to reach the places where the tooth brush cant get into.
Once you have done that, the next step is alcohol-free xylitol based mouth wash. Caries bacteria have trouble digesting xylitol so this reduces the presence of them in your mouth.
Only after you have done that, are you ready for something better than fluoride. Fluoride is a remineralization agent. Your saliva also contains calcium that helps your teeth remineralize. So the next thing you need is a more potent remineralization agent. Basically your tooth paste acts as a more concentrated saliva. Because of that, it is actually better to use e.g. fluoride in the morning and a different agent in the evening.
The classic options are bioglass (novamin) or hydroxyapatite. The latter is also available as mouth wash.
