Same here. Nothing to do as stopping the hard brushing stopped recession progress and gum graft is a heavy, expensive procedure that definitely leaves marks on the gums. It also makes me queasy knowing you’re basically getting gums grafted from a donor who died. Mine are recessed enough that it can get painful brushing after eating too acidic foods but not enough to justify the procedure. For acidic foods, I rinse my mouth with baking soda dissolved in water right after eating and it helps a lot. Dentists can also apply fluoride to the exposed parts but it tastes horrible while they do it, and only lasts a few weeks before it’s gone.
