Gum problems

afterglow

Hi all
Hope okay to post this here.
A while ago, I had to get a load of work done, fillings really, thankfully no extractions. I hadn't been to the dentist in years because of my fear of needles.
When I went to the dentist last time, she talked to me about a lump on the back of one of my gums on my bottom teeth, said it was something to do with plaque.
She said I have to get it removed but it takes ages on medical card at dental hospital, and that she was putting my name down for this proceedure.
I now try to take care of my teeth but admittedly sometimes I am probably not as good with it as I could be, meaning I only brush once instead of twice, and I can't floss because I'm visually impaired and have no idea how it's done.
Now the same gum where that lump I mentioned earlier has like a soft lump on it now as well, this is on the top of the gum, but on the same bottom tooth.
It has felt soar when I touched it over the last few weeks and tonight I was trying to see if a little pressure on it would make it come out of my gum as it's annoying.
Does anyone have any idea what this is, and is it my fault it's there, and how can I prevent needing more fillings done in the future? The thought of that scares the sh*t out of me.
Thanks and sorry for length of the post.

see your dentist urgently , visually impaired doesnt preclude you from flossing, I have two blind patients in my list and both of them successfully floss their teeth without any issues

Most dentists/hygienists are very good at explaining flossing or other procedures to patients. I admit I felt sheepish as an adult being told how to brush my teeth and floss properly but boy am I glad I did. I had no idea what I was at when I was younger.
