Which teeth are classified as succedaneous?

Succedaneous teeth refer to the permanent teeth that replace primary teeth, which are also known as "baby" teeth. In this context, primary teeth are shed and replaced by their permanent counterparts. The primary teeth consist of incisors, canines, and molars, with the first two types specifically being replaced by succedaneous teeth.

The permanent anterior teeth (incisors) and premolars replace the primary incisors and primary molars, respectively. This classification underlines the developmental sequence where these specific permanent teeth emerge in place of the corresponding primary teeth. Thus, permanent anterior and premolars qualify as succedaneous because they succeed, or replace, their primary counterparts.

Other options, while mentioning tooth types, either list teeth that do not replace primary teeth (like primary molars or canines themselves) or incorrectly include permanent molars, which do not have primary replacements. Thus, the choice that correctly identifies the succedaneous teeth is indeed the permanent anterior and premolars.
