Anyone fix "black triangles" between their teeth?

[Nickname1980]

I've just had a lot of gum work after gum disease. It seems to have gone really well but... I have the most awful "black triangles" now where my gums have shrunk back and recessed. It goes to show how bad my gum disease actually was without me realising

I feel so self conscious now though.

Has anyone had their black triangles fixed in a way they're really happy with?

I already have quite big teeth and all the treatments I've seen seem to make your teeth look bigger...

Is it possible for you to get the teeth filed and then use a brace to bring closer together? I was quoted £5k for this and didn't go for it.

Have you considered a gingival prosthesis?
It's usually impossible for anyone to notice their presence.
With any removable appliance, plaque control/ oral hygiene has to be impeccable to avoid exacerbating the underlying periodontal condition.
