Lump on gums

[MakaJ]

Hi,

about two weeks ago I started experiencing a mild toothache in my bottom right 6. I attributed it to the fact that I recently got a filling in my upper 6 and that it's probably connected in some way or form.

However a couple of days ago, when the pain was almost gone, I started to notice a lump on my gums beneath the bottom right 6. At first it didn't hurt when I pressed against it, but it is starting to grow ever more sensitive.

I have already booked an appointment with my dentist, but as it is scheduled 2 weeks from now, I'd like to treat the infection by myself as much as possible (I do brush twice per day and floss every day aswell).

Is there anything I can do by myself?

While sore, it doesn't look too red and it doesn't look like it is bleeding or has pus coming out of it, so getting down to the infection (if that is what it actually is) might be difficult. Any time I have an open sore/infection, I use hydrogen peroxide in my water pik to clean out my mouth and in 3-4 days it's all better. (I know you can swish with the stuff but it doesn't taste good to me so I can't do that)

I might suggest some over the counter pain meds, like Advil or Tylenol, to help with the pain and inflammation.
