Preferred toothpaste brand?

[Kalinoche buenanoche]

i'd like to give active charcoal toothpaste a try sometime as well.
The dentist i saw recently told me that she could not find any cavities at the spots that hurt when I chew sweet stuff. She said that maybe it's due to the enamel being worn off (maybe because of the way i brush my teeth or sth) and she applied a paste of sodium fluoride that i was supposed to keep for a couple of hours (no food). The difference was amazing and I think i could use a second application.
Anyway,i'd like to start using a toothpaste that contains this ingredient but those are normally sold at pharmacies and I keep forgetting to go there. Also, now that I know that the pain is not due to cavities i'm like hey maybe I can use it as a reminder to eat less sugar lol <3

as of late,i've been turning around the wheatgrass shot in my mouth before taking it down thinking it might benefit the ph and protect enamel
