Nearly three weeks ago I had four porcelain bonded crowns put on my
upper incisors. The upper left central and lateral incisors had both
turned black as a result of long-ago root canal treatment, so posts
were put in before those two crowns were fitted. I'm delighted with the
appearance of the crowns, and getting used to the pleasures of
unembarrassed smiling again. However, I've been noticing the past few
days that the crowns seem every so slightly unstable in the sense that
if I "suck" my teeth (if you know what I mean), there is a slight
sensation of them "giving" way and then subtly moving back into place
when the pressure's released. There's not quite a click, but a definite
sense of subtle movement as they settle back. After all the processes I
went through re the crowns, which as I said look fine, I'm  reluctant
to go back to the dentist esepcially over something that may not be a
problem. Is this feeling of slight instability, which I am particularly
conscious of when I focus on it but which is in no way serious,
something normal? I'm 56 years old, so I suppose there may anyway be
some "give" in the roots and gums.
