For the past few years, I’ve had a minute growth in the roof of my mouth. It’s about the size of a small pimple, but it’s rock hard. It’s just a bit lighter than the rest of the roof in color, and if touched too hard (i.e., tongue, food) can feel irritated. Now, it’s been there for years, but these past few days it has somehow managed to become very annoying.
What is this? 
Something you should see a doctor about.
Well, my mother has one and the dentist said it was harmless. However, she can’t recall what it was properly called. I believe it’s hereditary, if that helps…
I would have it checked by a doctor or dentist.
This one time, in real life, I went to my doctor with an un-explainable thing in my mouth, they told me to wait a couple of weeks and come back if it didn’t go away and they would test it for cancer. Turned out it was some sort of irritated/calcification of a salivary gland, or something. that went away. And then a year later or so it came back, but went away in 14 days. And then a year later it came back for 13 days, and I started to think it was going to be an annual event, but then it never came back.
I just got one last Wednesday on the inside of my gum, it feels like a piece of sand. Coincidentally I’m going to the dentist this coming Wednesday for something else, and I’m going to ask him what the hell it is.
In the roof of my mouth, I have a small bump that’s been there for awhile. On my last dentist visit, he took x-rays of my mouth and discovered that there was another tooth (upside down) up there. :eek:
My father had something like that when he was a teenager. They had to surgically remove it.
Ooh, me too Monica! In my case the orthodontist sent me to an oral surgeon who uncovered them. Then my orthodontist stuck braces on 'em and pulled them down into place. Since they were protected all those years they’re a little larger than my other teeth and so I have itty bitty fangs. Others in my family have had the same sort of thing revealed in dental x-rays, so maybe you and your mom share this, Daoloth. I vote for checking with the dentist, just to be sure.
I have no idea what your unidentifiable lump is, but I had something of a very similar sounding nature on the inside of my cheek. I chewed it off in French Class the day after I got it, and it didn’t grow back. That was last year, and my mother (who’s an RN) said it was probably just irritated skin.
Since chewing it off doesn’t sound like it’s so much of an option in your case, I also vote for the dentist, just in case.
