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
My dental hygienist told me not to rinse. "You're paying for the fluoride, why wash it away?" Makes sense. The dentist told me not to use mouthwash, because it upsets the mouth's natural pH.
My biggest find lately is silicon toothpick thingies - interdental brushes. They get to crevices floss can't reach.
Oh, it gives some physical shudders and looks terrifying to me :-). That felt pretty strong so I had thought that it might be a reaction most folk have.
