Question
it was unusually smoggy nearby today.  when the dew point temperature is reached, will some of the smog fall with the dew?

Answer
Hi Ann

Well, no, because dew does not fall; what happens is that moisture in the air comes in contact with a colder object on or near the ground and condenses into liquid moisture on the object(s).

As to smog leaving your area, there are two possible mechanisms: First, wind moving into the smog area and blowing the smog away; second, a rain event that "washes" the smog from the atmosphere to the ground.
