Hello, yesterday I had my teeth professionally cleaned with ultrasound (it felt like something sharp was going underneath my gumline) and "sanding" - like fine sand solution and a powerful jet of water going everywhere. My gums hurt a lot now, and seem somewhat "shrunk". The oral hygienist said that I had quite a lot of pigment but no tartar, plague. or gum disease anywhere. Is the soreness of the gums normal? When will it pass? Is there anything I can do to make it pass quickly?
