Frictional Keratosis is a benign reaction of the oral mucosa to chronic mechanical irritation. This condition leads to a thickened, white patch on the affected tissue.Frictional Keratosis commonly arises in areas where frequent rubbing occurs, such as where the teeth meet the cheek. Persistent irritation, like that from dental appliances or cheek biting, prompts the mouth’s protective response. This response manifests as a tough, whitish lesion that helps shield the underlying tissues from further trauma.
