(Concern) Gum improvement

I think my gums have receded a lot.

In the case of the lower teeth, about 1cm of the root is visible.

So I think that's why the gums are becoming weaker.

I regularly get scaling, use dental floss, try using a toothbrush for molars, and have even tried an electric toothbrush, but since my teeth are not aligned properly, I don't think my dental care is effective. Is there a way to improve this?
