Mouth Injury
Canker sores often develop when the mouth’s soft tissues are injured or stretched, for instance, during a dental operation or teeth cleaning. In addition, damaged or chipped teeth can create painful sores, and braces with protruding wires may irritate the inside of the mouth. On the other hand, canker sores may also develop from unintentional bites inside the cheek, tongue, or lips. Some patients can develop habits of clenching or gnashing their teeth, mainly during sleep. However, mouth sores accompanied by bleeding gums may signify periodontal disease or inflammation.
When the protective lining of the mouth or the mucous membrane becomes damaged or disappears entirely, the condition is called a mouth ulcer. Pain, swelling, and even minor wounds may result from biting one’s tongue or chewing one’s lips. Mouth ulcers may also be caused by rigorous brushing and flossing and using a hard toothbrush which can aggravate the mouth’s soft tissues and cause minor wounds. Individuals who actively play sports are also at risk since they are susceptible to injuries and body cuts. Drinking hot beverages or food can also burn the oral tissues. These injuries may lead to blisters which develop into ulcers as their outer layer breaks down or ruptures.
