By the time your child cuts his or her first molars, you've become adept at addressing their teething pain. But molars coming in at this age might feel like a bigger hurdle in your child's oral development. As much as they have a larger surface area, however, there isn't a significant difference in their eruption process compared to other primary teeth.
What Primary Molars Do
Primary molars are normally the last teeth to erupt and the last to fall out, making way for your child's permanent first, second and third molars as described by the American Dental Association (ADA). Your permanent first molars have a unique job: Known as the "six-year molars," per the ADA, they serve as the first "placeholders" in your mouth and set the stage for the shape of your lower jaw as it supports the placement of the rest of your teeth.
