PS: I've considered getting yet another opinion to keep the situation
honest here.  Would a Periodontist be a good option, or should I try
another family Dentist?  (A previous Dentist suggested I may be having
problems with 13-15 because of underlying gum issues.  And, Dental Rinse
[Ciclopirox - not sure of spelling] seems to help relieve the pain, so I
wonder if the tooth is pushing funny on the gums somehow).

I'd greatly appreciate any help/advice as I am going absolutely out of
my mind with constant (now 3-year long) pain from this [that's when the
first restoration [CEREC] was put on 14.  It was replaced by a porcelain
crown 6 months ago].

Really a tough call.  There are often inaccuracies in registering the
bite when a crown is made, but usually this can be checked and corrected
before the crown is cemented.

As a patient who's had more than his fair share of bad dental work by
bad dentists, I say that if I were you I would
1) get a 2nd opinion about the bad fitting crown
2) if the opinion is that it fits badly, and should be re-done, then
you have to decide: Is the dentist who did it CAPABLE of doing a good
job if you re-do it? Or will it just be botched again? Or should you
have it re-done by a - hopefully - more competent dentist?

Then you have to decide if you can get any money back from the
original dentist who did the bad crown.

I had a situation where my wife had a bad root canal causing her to
have to have an apicoectomy. We got severeal opinions that the root
canal had been botched, and so I sent a registered, certified letter
to the dentist stating that I knew the root canal had been botched,
sent him copies of the opinions from other dentists, told him that it
cost my wife a lot of pain in having to have gum surgery to fix it,
and that I wanted the money back that I paid for the root canal (and
if he would pay me that I would not sue for damages for having caused
the need for the gum surgery, pain and suffering, etc.)

After a couple months of follow-up phone calls and letters, and
finally threatening to file a law suit in small claims court, he
agreed to pay me back for the root canal which was around $600 as I
recall.)

So you probably do have some legal muscle in getting him to pay you
back for the bad crown if you can present enough evidence that it was
done badly. You can also threaten him with complaints to the American
Dental Association or local or state dental association if he's a
member, or whatever equivalent you have where you live.

Good luck.

Also: I had a crown re-done and it was no big deal, he just popped off
the old one, and put on a new one.
