Hello mam....gum diseases are like sslow poison they dont generally give any pain but as the gums are receeding that means there is infection in the gums and that arises due to the tartar in the gums ( subgingival) and so cleaning is the first mode of treatment to stop the gums receeding further more. Later u might have to undergo flap surgery for ur gums depending on the bone levels around your teeth. Pls take out a dentap opg. And brushing or flossing is not going to help now. Gums will never grow back automatically now.
