facial swelling

For the past couple of months I have noticed some swelling on the left side of my face, in front of the ear area.
It is soft, easy to push in and is painless.

The puffiness or swelling disappeared when I used prescription diuretics. I have tried reducing the intake of salt, refined carbs, caffeine, and drinking lots of water, to try to get the same effect without any luck.


I'm starting to wonder if this may be a dental issue. I'm not a very good brusher and I do have inflammed gums. I have had most of my wisdom teeth removed, but not all of them. I was wondering if this could be caused by the last wisdom tooth attempting to push through.
