As the old Fifties song goes, “Little things mean a lot.” They can also be the most irritating, like a hangnail, a papercut—or a certain kind of oral sore. Although rarely concerning to health, this particular kind of “bump” in the mouth can be unnerving.

Although known as a traumatic fibroma, it's not as dire as it sounds: It's simply a small wound created when your inside cheek gets in the “line of fire” between your teeth while biting or chewing. It's an experience most of us have had, and though it's a minor occurrence, it can make us wince with pain.

But the pain usually lasts only a few seconds—until the next time, which is a distinct possibility. The body creates a protective callous over the wound made of fibers (hence the name fibroma) of a protein called collagen. This creates a rise in the skin surface that increases the chances the area will again get in the way of the teeth and be bitten. Each bite leads to another layer of collagen, a more prominent rise and even greater probability of another bite.

Rather than let this irritating situation repeat itself, you can undergo a minor surgical procedure to remove the fibroma. Usually performed be an oral surgeon or periodontist, the area is numbed first with a local anesthetic and the fibroma removed with a scalpel; the resulting wound is then closed with a few stitches or a laser, in which case no stitches are necessary. As a result, the cheek surface flattens out and becomes less likely to get in between the teeth.

The dentist may also preserve some of the removed tissue and submit it for a biopsy to check for any cancer cells or other abnormalities. You shouldn't be concerned about this: Examining excised tissue is a routine step performed for a variety of surgical procedures. It's used to verify the tissue in question is benign, which in this case is the vast majority of the time.

After the procedure, you might experience some minor discomfort for a few days, usually manageable with a mild pain reliever like aspirin or ibuprofen. The procedure itself only takes about fifteen minutes, but it can provide you lasting relief from that bedeviling little sore in your mouth.
