Am I a good candidate for pinhole surgery? How much would this cost? (photo)

I noticed recession happening on the gums above my front two teeth which is super asymmetrical. I believe it’s because of switching to a new electric toothbrush which may have been too aggressive. I got bonding 10 years ago to close a gap, so I don’t want to look into reshaping, as it will make my teeth appear even larger. I do plan to have the bonding redone at some point soon. I also think maybe I should get the gums on the inside of my bottom front teeth done?
