No. plaque will accumulate there. Check between teeth with dental floss.
Ideally, it should be redone if this is true.

Overhang on the filling. Get if filed, with anesthesia if necessary.

Dental explorer, which is like a sharp pin.

What is the definitions of margins? Is it this kind of space
underneath the tooth I am asking about? i.e there should be no space
between tooth and gums?
How difficult is it to redo?

Is this considered poor work also i.e. the crown should have been
lower and no overhang necessary. Is the cement or overhang just going
to erode away, etc?

I asked the dentist about this and she feels it's fine and she is
comfortable with it. She did 2 crowns, an upper bicuspid and a lower
first molar.
I said that the floss does not catch on the mesial of molar or on
either side of bicuspid. She then used the floss on the bicuspid and
said: "see it catches there, too. If you maintain good hygiene, it'll
be fine."
Now I am worried. I guess I should get a second opinion?
I did get that office as a referral from a neighbor who has been going
there for a while, however they do charge about 2/3 of the cost of
others.
Should the floss not catch whatsoever?

This is an ideal, but it is not always achievable. For that matter I
sometimes catch floss between teeth that have never been filled or
decayed, much less crowned.
It's probably fine, but by all means get a second opinion if you have
any doubts.

That usually indicates night-time parafunction-

Tablet PC? That's a step back.
I personally like Cuneiform on a clay tablet but its way too slow for
me!

Darn,
Are you referring to both buccal and distal areas?
Have you seen the gum improve once parafunction situations are
resolved e.g. with NTI.
Is there anything else that can be done to make the gum go over the
tooth.
Should the area be cleaned/brushed/flossed etc in some other way or
best left alone?

Buccal

It should stop the progresion of the recession (as long as the device
dontinues to be used)

All areas of the mouth need to be clean.

Could parafunction cause something like that immediately or would it
take time. If a splint is worn can this still happen.
This was noticed on a new crown within 2 weeks. I don't know if it was
there immediately or not. The original tooth had nothing like that
before the crown.
Another crown was done on a bicuspid and no space between the gum on
any side is present.

A properly done splint should prevent this occurrence.
I doubt it could occur in a period of only 2 weeks.
