I think I spent a long time with Gingivitis. My Dentist and Hygienist did not mention anything, since then I have exercised excellent oral hygiene, my gums look and feel better, have I fixed the problem?

Q.
Mr Dunn I have a question for you please. I think I have periodontal/gum disease as I spent a lot of time with gingivitis where my gums would just bleed without being brushed and so on. I am not sure and have since seen my dentist. she did not mention anything just ummed and ahhed for a bit before referring me to the hygienist (which I was expecting as it was sometime since I had been). the hygienist also did not mention anything and after the scale and polish there was some minor bleeding .I have since exercised excellent oral hygiene and am due back in April. My gums now seem to be fine and don’t bleed at all,ever and aren’t nice and pink. Is it possible that I could have treated it or is it something that ‘needs’ to be fixed in another way and could still be eating away at me? thank you for your time and I’m sorry for the long question I just needed to explain fully my situation.
