First off, here is the best picture I could take of the hole left from
the wisdom tooth that I had taken out on Friday afternoon.  I only had
one of the upper molars taken out.

It's Monday now, and I still haven't had much pain throughout the
entire experience (haven't taken any painkillers or tylenol and I've
been fine).  I did have a couple questions though:

1.)  Obviously the biggest concern would be dry socket and/or
infection.  Considering I have no pain, I know I don't have either,
but I heard either could occur a few days after the surgery.  First,
does it look like my tooth (or hole) has a blood clot?  It's basically
a little blackness within the hole, so I'm assuming that's what it is,
but I really have no idea.  Also, when you dislodge the blood clot, is
this something that is very noticeable (i.e. a big chunk of dried
blood in your mouth?  I was told not to smoke within 24 hours after
the extraction, but I'm curious if it would be okay now that its about
3 days.  I've heard some say they smoked a day later and nothing
happened, and others say they smoked 5 days later and got dry socket.
I'm assuming this varies with the severity of the case.

If I did smoke, should I put in gauze to cover the area?  Also, is it
best to rinse with salt water after smoking?  How about in the morning
- is it best to rinse first then brush or vice versa?

2.) The paper the dentist gave me warned me about smoking and using a
straw, but what about other things such as blowing your nose or
coughing?  Is it possible for this to dislodge the clot?

3.)  What about alcohol?  I'm not an alcoholic, but I do enjoy going
out and having a couple drinks, so how long should I wait before I can
do that again?  Also, I generally use Listerine often and I know that
has alcohol in it, so when it is best to resume rinsing with that.

I know there are a lot of questions there, but I appreciate any
input!  Hopefully some dentists out there can help me out.  Thanks a
lot.
