I have read and asked professionals and read some more and finally have decided that brushing and flossing every 4 hours is ideal. Using a very soft tooth brush daily and a hard one once a week is ideal. A motorized brush is okay too but not necessary imo. And using a water pic with ozonated water is ideal. This would replace a need for bad bacteria killing mouth wash. I wonder if this routine would help with your situation.
Our dental health is not as good as previous generations probably due to our gut bacteria being so out of wack from lack of proper nutrition. There is one bacteria that every healthy human gut in the world is supposed to have that is in danger of becoming extinct! So this is why we must now keep our teeth brushed and flossed etc.

I think if you can live with stained teeth that the greens may be a good thing for remineralizing the teeth. I do not use tooth paste except a powder with baking soda once a month. There are some remineralizing pastes that are vegan you could try for sensitivity. I would try different things and see what works for you but look up the ingredients and make sure you are not using anything bad. I remember reading about someone doing a Gerson protocol to heal her cancer and was doing everything right except using fluoride toothpaste and her cancer was not healing. Then Gerson told her to stop the toothpaste and she did and then started seeing results of her cancer going away.
