What can trigger an ulcer?
Possible contributing factors include accidental bites, irritation from dental appliances, stress, and individual susceptibility. In some people, recurrent ulcers may be associated with nutritional deficiencies, certain medications, or underlying health conditions.
However, it is not possible to identify the cause simply by looking at the sore. Recurrent or unusually severe ulcers may need evaluation to determine whether another factor is involved.
How can discomfort be reduced?
Gentle oral hygiene, avoiding foods that irritate the sore, and choosing softer foods may make eating more comfortable. A pharmacist or dentist can advise whether an appropriate pain-relieving or protective product is suitable.
Most minor canker sores heal within about one to two weeks. If a sore persists for more than two weeks, repeatedly returns, becomes unusually large, or is accompanied by other concerning symptoms, seek professional advice rather than continuing to treat it as an ordinary ulcer.
4. Irritation Fibromas: Bumps Caused by Repeated Friction
An irritation fibroma is a benign growth of fibrous tissue that can develop in response to repeated irritation. It may occur on the inner cheek, lips, tongue, or other areas that are frequently rubbed or bitten.
These bumps are often firm, smooth, and similar in color to the surrounding tissue. They may develop slowly and remain relatively stable in size.
Repeated cheek biting, friction from a rough tooth, or irritation from a dental appliance can contribute to this type of growth. The tissue becomes thicker as part of its response to repeated injury.
Although irritation fibromas are generally benign, a person cannot reliably distinguish one from every other type of oral growth at home. A persistent lump should be examined, particularly if it changes in size, bleeds, becomes painful, or interferes with eating.
