Head Bang Test for Bad Root Canal

I had a bad tooth removed, #2, that had had a root canal and a post and apparently the tooth cracked, and a dark area around the tooth showed up on the X ray.  When I lightly tapped my head, my #2 and # 3 teeth would feel loose.

Now that #2 has been removed, I felt much better walking out to the car from the Dentist office from having #2 extracted.  I had sort of been feeling dragged down, lowered energy. 

Now Only # 3 feel loose, when I bang my head, lightly.  I have had a root canal in # 3 a few weeks ago, and they are ready to put a permanent crown on #3, but I am trying to figure out what indications tgher might be that will indicate whether #3 should also be romove.

 This is a real lesson for me, because I have not been brushing or flossing as often sas I really could have.  So I will try to be kinder to the rest of my teeth.  I tink I have some other root canals, but they are not bothering me, that I am aware of.

 Anyone have other tests for checking a bad root canal? 

 I mad an appointment with the Root Canal Dentist, so he can check the tooth out, maybe do some more cleaning of the roots, or whatever.
