When the permanent teeth begin to come in, the first permanent premolars erupt into the space left by the primary second molars. The roots of those primary second molars resorb as the premolars push upward, leading to the shedding of the primary second molars. This is why the first premolars replace the second primary molars. The other primary teeth have different replacement patterns: the second premolars replace the first primary molars, and the canines are replaced by permanent canines, not by premolars.
