Not sure if this is 100% scientifically backed but I read a bit by a dental hygienist on a forum that you shouldn’t rinse when brushing with proper toothpaste because it can help remineralize the teeth if when its not rinsed away after
Its annoying but its a good way to cut down on mindless snacking at the very least for me so its something I do sometimes. Hope its not voodoo
I used an e-brush for all my life and only got cavities from lack of brushing and being negligent.
But you shouldn’t brush right after eating.
Eat something, wait 30min, then brush.
That’s how I do it for breakfast.
