Another possible cause is irritation from dental appliances, sharp teeth, or repeated accidental biting. Continuous friction can cause tissue swelling and small growths known as fibromas. These benign lesions are generally not dangerous but may continue growing if the source of irritation remains.
People should also watch for signs such as persistent ulcers, unexplained bleeding, difficulty swallowing, ongoing pain, or changes in speech. While these symptoms can result from many different conditions, they should never be ignored when they last longer than expected.
