A little over 24 hours ago, i had an implant crown fitted on tooth #14. since placement, have had a sensation of tightness / pressure. no pain. is this normal? feels weird?

I would say it not unusual. You just wait for another day or two. If sx persists or gets worse, which I doubt, you can call your dentist.

It can be adjusted by your dentist if the feeling persists.

Restoration may be infinitesimally wider than the space available between the crown and the adjacent teeth. This microscopic difference helps prevent food impaction. Should disappear in 48 hours. If not, call your Dentist.
