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
Rinsing with salt water seems to work well for me. I have no idea what the science says about it though. But there is some talk in new treatments about ionizing stimulating healing, and I wouldn’t be surprised if salt water does a bit of that too.?
I also wouldn’t be surprised if it helps remineralize. Very subjectively it feels like it does a little, but it’s easy to fool oneself with wishful thinking. Preferably have a dentist monitor results.
My hygienist recommended that I use salt water instead of mouthwash, so I’d think you’re probably barking up the right tree
