What are mamelons?

Mamelons refer specifically to the three prominent, rounded projections found on the incisal edge of newly erupted central incisors. These structures are a normal developmental feature in primary and developing permanent teeth. They are typically present in teeth that have erupted recently and are more common in children. As the teeth undergo normal wear and functional use, these mamelons gradually wear down and can become less visible as the tooth matures, giving way to a smoother incisal surface.

The emphasis on mamelons being bulges is significant because it highlights their unique anatomical formation, distinguishing them from other types of enamel features like linear elevations or areas where grooves converge. Understanding the function and development of mamelons is important as they can offer insights into the eruption and alignment of teeth, especially in pediatric dentistry.
