so my tooth was really loose. like i could twist it backwards with no pain because of an adult tooth that came up. except for one side of the tooth the vein was still connected. really thin though. so i twisted it too far backwards (i think) and it became even loose where i pulled it out with like no pain at all. but when i pulled it out theres like a thin vein still there in the gap of the adult tooth and my other tooth. what do i do?
