(1) Traumatic ulcer: This is a type of ulcer directly related to local stimulation. Traumatic ulcers may be caused by residual crowns left by fractured teeth, stones deposited on the surface of teeth, uneven or misplaced teeth, bad habit of biting cheek, sharp edges formed after tooth wear, and rough dentures.
