**Core Concept**
Riga-Fede disease is a rare condition characterized by ulceration of the oral mucosa in infants, typically affecting the tongue, lips, or buccal mucosa. This condition is often associated with the sucking reflex and is thought to result from the trauma caused by the infant's vigorous sucking motion.
**Why the Correct Answer is Right**
Riga-Fede disease occurs due to the repeated trauma to the mucosa as a result of the infant's sucking motion, leading to ulceration. The condition is often seen in infants who are vigorous suckers and may be associated with other oral habits such as tongue thrusting or lip biting. The ulcers typically heal spontaneously once the sucking motion is broken.
