Does This Sound Like It Could Be...?

On the inside of my cheek, about the center of it, I have a little hole. It's like a small indent, like if you poked it with a pin, you know what I mean?

It's been there for a bit of a while now, a few months, and I don't think it's gotten any bigger or smaller...  

 I don't have any health insurance, so I haven't gotten it checked... it doesn't hurt, but I can feel it if I run my tongue over it, and I can see it if I look in the mirror..... 

 Does this sound like something I should be worried about?

From personal experience, be safe and get it checked.  I've never heard of your symptoms but the general rule is if something "new or different" appears and lasts more than three weeks have it checked by a doctor or dentist.   It's always better to be safe than let something go, as with any illness early detection is key.  You may spend $100 for nothing but peace of mind and good health is something money can't buy.
