I like to work without fluoride and I suggest that the toothpaste be free of it. And I give the same recommendation when it’s about oral rinses. The characteristics of a good oral rinse is that it doesn’t contain preservatives, preferably that it doesn’t contain folic acid, vitamin D, coenzyme Q10, flavonoids and natural herbs like chamomile, peppermint and sage. Preferably, that the bottle is amber color: amazon.
Any one that you can find in stores like Sprout’s or Trader Joe’s will be of greater quality than a commercial one.
