Hello. I Seem To Have Detachment Of My Gums On

hello. I seem to have detachment of my gums on my front lower teeth. It doesn't look like i have plaque on my teeth and it looks clean. I just recently started flossing until 6 months ago and i have had bleeding on my gums before when i flossed. But now i barely bleed anymore. But it seems like my gums in the front lower tooth is slightly ripped or detached. its not noticeable but if i push it with my finger it is loose. I think i might have gingivitis but it doesn't seem like its severe. My teeth looks clean and i don't bleed anymore. I thought it would've healed by now but the gums still look detached in that one tooth. Also i believe i see signs that my gums are receding but have stopped. I haven't seen much change in months. Even though it's not noticeable the signs are there. I'm just worried.
