What does dreaming of teeth falling out mean in relation to my current Islamic school environment?

Assalamualaikum Many times I dreamt that my teeth were about to fall or had fallen (3 years ago). The interpretion that I got was that I was not stable at the school where i was teaching. ( I did not like that islamic school as there was many unislamic things going on there). Now I am in a more islamic school and stopped getting that dream, I am happy here because of the islamic environment though there are still few things that need to be done more islamicly. Now I just dreamt few weeks ago that some of my back teeth fell and i even went to the dentist to fix it but she did not get the opportunity to do it (in the dream). I would be grateful to know the interpretation Jazakumullah
