Do I have gum recession and what can be done?

I had a dentist appointment last week and asked about gum recession they didn’t seem concerned and said my X-rays and gums looked healthy they did give me an orthodontist recommendation but other than that no cavity’s everything’s good but I’m worried about gum recession on my top and lower front teeth I might be imagining it it dosent cause pain or discomfort just is bugging me mentally and driving me crazy worrying about something I don’t even know is real
