What is the appearance of healthy gingiva often compared to?

Healthy gingiva is often compared to the surface of an orange because of its characteristic texture and color. The healthy gingiva exhibits a firm, resilient structure that has a slight stippling or dimpled appearance, similar to the pebbly texture found on an orange's skin. This stippled surface indicates proper health and is a sign of well-vascularized tissues that are not swollen or inflamed.

The comparison to an orange highlights the importance of texture in assessing gingival health, as gingiva should not be smooth or too shiny, which can indicate disease or inflammation. The other options, while they describe various surfaces, do not accurately represent the unique texture and appearance of healthy gingiva, which should embody that slight roughness and firmness associated with the surface of an orange.
