I just had three wisdom teeth removed and it was recommended to rinse
my moth with a salt water solution. I have looked around and this
seems pretty common but I cant find any "Why" about this. What makes
this effective? Am I taking my fresh water mouth flora and putting
them in a salt water environment? I hear some people also use baking
soda and water to rinse there mouths? What's happening in this case?

Do NOT rinse with anything for the first 24 hours.  You can knock the
{*filter*} clot out and restart the bleeding, and/or predispose yourself to a
dry socket, which you do NOT want to get.
After that, salt water of the right concentration is soothing.  It
should be mixed to be about the same concentration as that found in
tissue fluid--about 1/2 teaspoon in 8 oz. of warm (not hot) water.  You
gently dislodge debris this way without causing damage to the wound.

Salt water is ok, but camomile tea (lukewarm) is better if you have
any.

That could get expensive, especially for someone requiring many
extractions :)
