i don't have any of the signs of gum disease - there's no bleeding, no redness, no swelling.

they're just receding.

and, whether it's due to genetics or brushing or something else (i quit smoking in 2016 and, when i did, i had no gum recession. so, this has developed entirely post-smoking. it's an easy answer to blame it on smoking, but it's wrong.), i don't know....

but, i need an expert to look at it and tell me what can be done about it.
