I had a temporary crown done, it kept coming off. Haven't had anything on my tooth over a month, is it going to be damaged??

I got a temporary crown the last week of October , it kept coming off, I went back 4 times. So, I've been without anything on my teeth since November. I've called them back and I keep getting the answering service!! No call back. I'm just wondering is this damaging my teeth?? And I've paid for my permanent already, I was thinking of just having it pulled.
