Abstract
Chronic traumatic ulcers (CTUs) of the oral cavity are frequently brought on by repeated mechanical stress, such as biting or friction from dental appliances, or sharp or broken carious teeth. Although they are frequently disregarded, patients with nonhealing ulcers in the mouth should have CTUs taken into consideration. This report highlights the significance of differential diagnosis and suitable treatment options by discussing a case of a CTU that persisted on the tongue's right lateral border.
