Tooth and Mouth Problems

I have 4 dental amalgam as old as 17 years. Extraction of upper and lower wisdom teeth and have much bone loss around. One of my amalgam filled tooth is scheduled for adv rct. So I am looking for best dental cap for that. As i have toothache and gum swelling round the year so I really want the cap to be the best fitted. And yes I have ultra sensitive teeth. Mostly in my lower jaw. And have gaps between teeth.

I got crowns on front two teeth on the lower jaw and sometimes i cannot close my mouth when i do, upper teeth hits lower teeth and i cannot close my mouth i have to forcefully close it and then my teeth starts paining. I dont know why this happens. when i wakeup there is  gap and upper and lower teeth does not even touch each other but in the evening or at night they rub with each other very heard if i close my mouth and this doesnt happens when i wake up in the morning and when i asked about this problem to a dentist they didnt gave me any good reason for this. When i consulted for this problem the doctor reduced lenghth or upper front teeth and reduced lenghth of my crowns and because of this my crown is now chipped but now i have some sort of relief because upper teeth are now smaller and lower crowns are now thinner and smaller but why this problem is only happening at night or evening and not in morning?
