Yesterday had back molar prepared for crown and temp put on .Today the
gum around the tooth is swollen and very sore there is also a large
ulcer near the tooth also I think this could be because the saliva pad
was cutting into this area when the work was being done why do they
have such sharp edges on them?Anyway is this normal ? Thanks.

Hard to tell. _Some_ inflammation around the gum may be seen, especially
if the prep was made to under the gumline. This would be unusual in the
back tooth area unless it would be needed to have enough tooth for the
crown to grab onto. If it doesn't resolve tomorrow, I would say ask to
have it verified by your dentist.
Hope this helps

Finally: take out the TRASHH

thanks for your reply.Yes there was not much tooth left so prehaps that
is why it had to go under the gumline further than what is considered
normal.Why did my dentist push this string type thing under the gum it
had a bitter taste also, any way it is feeling a bit better today I am
rinsing with this stuff which helps with the pain the worse thing is
this large ulcer on the outside gum which I think is from the saliva
pad.Thanks again

The string is called 'retraction cord'.  If a crown prep goes below
the gumline, it can be more difficult to get the impression material
to the bottom of the sulcus (the impression must record all of the
detail of the preparation for the lab to make a good fitting crown).

The retraction cord pushes the gum slightly away from the margins of
the prep and the bitter taste was a hemostatic agent to stop blood
seepage into the sulcus while taking the impression.

Some patients like step by step descriptions of treatment, and others
just want to get in and out with the fewer details the better.

Did they wet the pad before removing it or just pull it straight off
after treatment?  Could also be an injury from the suction tip.  Soft
tissue usually heals quickly in the mouth.  The idea is to create as
little colateral damage as possible, but s**t happens.

Thanks for you great answer i should really be asking my dentist these
questions but he seems so rushed usually is running late and I suppose
time is money.Any thanks .

I guess that dental care is often delivered at a pace that precludes
a lot of chit-chat.  I much prefer the days that everything runs on
schedule and I have plenty of time to discuss what I'm doing and why.
I imagine the patients enjoy those appointments more than ones as you
describe too.  I'd like to say that I never have that problem, but
it happens more often than I would like.

Sometimes this is due to production goals of the office.  Sometimes it
is due to poor scheduling.  Sometimes it is due to a high demand for
one persons services.  Often it is exacerbated by accepting low fees
with some insurance plans where it's hard to make money without very
high production.

In my case, there is a larger demand for dental services than there are
dentists to deliver those services.  Add in the fact that I don't want
to work six ten hour days per week, and I am often very busy each day.

Something to consider,

Fawks

Maybe there is some excess temporary cement collected around the gumline
that wasn't removed.  Could be that the area near the cheek was very dry and
got irritated by the pad but the area needs to be dry to do certain
procedures on the tooth too.
