The most common lesions arising due to trauma are tongue/cheek biting, frictional keratosis and chronic traumatic ulcer. Causes of trauma to oral mucosa For the development of malignancy, it is usually a long term, repeated, minor injury which can be caused due to a number of causes. This injury can be caused by teeth, dentures or some inherent or acquired disturbances in dental alignment or occlusion.
- Sharp or broken teeth,
- broken restorations/ tooth fillings,
- ill fitting dentures,
- loose dentures are the most common causes for such injuries.
