Phoned the dentist today and he asked me to go in.
When I got there he had a look and poke about my mouth and said that the reason it had came out was because my gum was swollen and it had pushed the screw out.
As I am back for my next adjustment on the 3rd July he said he would leave it out for now to let my gum calm down and heal as if he put it back in while my gum was still swollen, it would just push out again and come loose.
He left the elastic bit in tho so that’s kind of annoying when I’m trying to eat but apart from that there are no issues. Will update after my next appointment on the 3rd 🙂
