*detailed question* Gum issue? Abscess or something else?

For the last several months, I have had reoccurring lumps of sorts on my gums. They started about a day after my last dental visit, where I had x-rays and all of the other usual dentist checkup-y things done and they didn't find any abscesses or any signs of oral cancer, or anything wrong except for some cavities that needed to be filled and early signs of gum disease due to poor dental care when I was younger and lack of checkups for a year or two. As far as I know abscesses or oral cancer (at least not in the stage of what I would consider to be a tumor, if it were cancer) don't just "appear" in a day after having x-rays and a full workup done on my mouth. I do have 2 teeth with cavities in the back of my mouth (one on each side, actually below where the lumps are) but the dentist didn't think either of them were THAT bad, but should be filled as soon as possible, though due to me not having any insurance he didn't see any reason that with proper personal dental care it couldn't be taken care of a little bit later when things were more financially stable and I had my insurance issue settled. I do have my wisdom teeth coming in slowly, but they are only coming in on the bottom. For whatever reason, I don't have top wisdom teeth. Anyway, I have these lumps on my gums, and everything I have ever read about abscesses says that they cause pain, usually immense pain, but mine don't cause any pain at all. They're not even a tiny bit sore, and they go away intermittently but then raise back up, usually in the morning when I wake up. They are usually always above the back teeth on my gums, the one on the right is about the size of a jellybean, and is newer than the one on the left. The one on the right feels like I can move it with my tongue, like I can push it around and lift up part of it with my tongue, but this is a new thing and before the lump has always just been a solid lump, never anything movable. The one on the left is smaller, and usually less inflamed than the right one usually. They feel as though they're filled with something, though I've read and heard that when an abcess bursts there is a VERY bitter and unpleasant taste in your mouth from the pus. When my... well, whatever they are, go down, I don't taste anything in my mouth, much less anything bitter or gross, and they don't hurt when they go away or when they re-appear. They slightly vary in size, but are always smaller than the jellybean size, which is the biggest they ever get, and they don't get that big very often. As for color... the last I checked they are the same pinkish color of my gums, not white or yellow or anything. I don't have any underlying conditions, I am otherwise medically healthy. Any ideas as to what this is or how to go about treating it? I went on a cycle of antibiotics back in September when I first was terrified I had dental abcesses, but they didn't go away. My GP thought that maybe they weren't dental abcesses or a dental infection... but wasn't sure what they were since there was no pain and they didn't go away with antibiotics. I read somewhere about some kind of condition where you just get growths on your gums that eventually go down or go away, and I can't get to my doctor/dentist until March again because of insurance reasons...again.

Are they behind your last molars, on the tissue where your wisdom teeth will erupt? If you can take a picture and post it, that would be helpful. I do not think that they are an abscess because your dentist would have seen an infection on the x-ray. Also, I do not think that they are pyogenic granulomas. These take more than two days to develop. It seems that these vesicles are caused by some irritants while you were at your dentist. As long as they go away within two weeks, you shouldn't worry. If they last longer than two weeks you should probably see you dentist asap to rule out anything serious. (oral cancer doesn't typically present itself in this manner) You may want to rinse with a cup of warm water + 1 tsp. salt. And maintain good oral hygiene! EDIT: please note that pyogenic granulomas, like most granulomas or fibromas, are usually caused by chronic irritants (i.e. subgingival calculus aka "tarter"), not going to an hour long appointment. Good luck
