Where are mesial and distal marginal ridges located?

Mesial and distal marginal ridges are anatomical features found on both posterior and anterior teeth. These ridges are the raised borders that outline the mesial and distal surfaces of a tooth. On anterior teeth, which include incisors and canines, the marginal ridges aid in the overall contour and function of the tooth, facilitating bite and aesthetics. On posterior teeth, such as premolars and molars, the marginal ridges serve a crucial role in occlusion and help in maintaining food flow during chewing, preventing food from becoming trapped between teeth. Therefore, their presence across both types of teeth supports a common theme of oral anatomy where foundational structures aid in both functional and aesthetic roles in the dental arch.
