Tooth pain 6 weeks after new composite filling

[Ktdtexas]

6 weeks ago I had to have a filling replaced with a composite filling and I also had a crown on one of the last lower molars.  I had issues with the temporary crown, and those were quickly resolved by my dentist.  Last week, my new crown was put in place and I also seemed to.be having some sensitivity issues.  The dental assistant used something along the gum line that would be temporary, eventually wearing off.  Currently, the tooth with the composite filling is hurting.  Not throbbing, but aching.  I cannot chew on that side, and I am also slightly swollen on my cheek in the same area.  We are currently out of town.  Wll return home tomorrow.  Should I contact my dentist now or just wait for Monday, which is 2 days away.

There's a number of possibilities due to multiple treatments.

The filling could be the problem due to the deep cavity. The nerve could be infected or inflamed and its causing the pain.

It could also be the crown.  The bite may be off (resulting in more pressure and pain), there may be some cement stuck somewhere that's irritating the area or it may also be a problem with the nerve.

Unfortunately it could be more than 1 of those things too...

The aching has been intermittent since the original composite filling was done 6 weeks ago.  The dentist did comment that the decay was quite deep.  I don't know the tooth number.  It is the fourth bottom tooth from the center.  The pain had been further back near the temporary crown.  When the permanent crown on thenback molar was put it, I didn't require numbing, but the suction straw was really painful, so they quit using it.  A week later,  this fourth from the center bottom tooth is extremely sensitive, can't put any pressure on it, feels like it has moved closer to the fifth tooth, my gum is bleeding when I floss, and I have slight swelling directly under that tooth.  Advil helps, but doesn't last the entire 6 hours between doses.  I don't think my braces 40 years ago caused this much pain!

I think waiting is okay.  Its hard to predict when it may flare up and worsen.  When did the aching start exactly?  The day the filling was placed or the day the cement was placed?
