Did I screw up my gum graft?

I got a free tissue gum graft this morning- tissue taken from the roof of my mouth and grafted below 24 and 25 where I’d had some mild recession. Procedure went smoothly and I haven’t had much pain.

However, I stupidly didn’t think while I was brushing my teeth tonight. I obviously avoided the front of those teeth, but I brushed the back of them. Earlier, I could feel my sutures wrapped around each of those teeth. Since brushing, I can only feel the suture wrapped around one of them. I’m worried that I broke the suture that was wrapped around 24.

I’m not bleeding and don’t feel any additional pain, but I’m worried that that suture was holding something up and that I may have screwed up that side of the graft, especially since the procedure was only done 12 hours ago.

Has anyone lost a suture this early in the healing process? I feel so dumb!
