3 days ago I had 2 up my upper back teeth extracted. At night when a lay down I have this salty like drainage that comes in my mouth. I try to always spit it in a cup just in case it’s infection. I little bearable pain I do have can 9/10 be stopped with Tylenol. However, I’m very worried that I have an infection by the way my sockets look. Could someone please help me out?
