Is it OK to have metal molar bands near an extraction site? Is my bottom wisdom teeth extraction site healing correctly? (Photo)

I am completely aware that I have to brush a little better which I am trying to do now and I'm doing better at it. I just need to continue. But I took out all of my wisdom teeth out on the 27th of February. I am just wondering if the metal molar bands will affect my healing. Plus, I had to get a bone graft on the two bottom wisdom teeth extractions.
