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
All the advances in toothcare seems to be around fancier electric brushes or other gadgets, but regardless we’ve never been able to move away from ‘brush for 2 minutes’. I want some fancy device I just bite down on and it zaps my whole mouth clean in 5 seconds.
