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 do the xylitol gum! I think countries in asia regularly markets this as part of good dental hygiene for those reasons you listed. Some of the gum containers advertise, white healthy teeth. Not sure why the US doesn’t promote xylitol gum more.
The USA wants sick and diseased citizens because it’s good for the economy.
