I'm a recurring patient, so my stuff is t&t from the standpoint of btdt. I'd never recommend anything I didn't already try or already believe to be effective.
Yes, that stuff helps w/swelling, bu moreso w/pain, ime.
The salt/saline dealio is gonna be most effective and less pain eliciting. Beyond that is stuff I know for mainly pain and possibly swelling. You can always do a cold compress on your cheek on the outside, but well, that seemed obvious so I didn't bother.
I know some people use tea bags on the gum line, but *I* don't know how. I don't know if it is used bags or not, what tea herbs to use, and any of that. I just don't know that. Nothing readily comes to mind, other than I've heard to do that.
And I mean, there is other stuff out there to be tried. I just don't usually say "try this" unless I've actually tried it. kwim?
eta: think about the work they just did. that'll make stuff swell. for a good clip. Just another wild, out there, thing to consider-how is your gum health? I was just diag'd w/periodontal disease this summer. I'm 36. Not sayin you have it or ever will, but ya know, healthy gums hosting healthy teeth mostly don't swell, like w/weather (you were supposed to laugh there).
Hang in there. You'll get fixed.
