Primary molar teeth fall out just like other primary teeth and are replaced by permanent teeth, according to HowStuffWorks. Primary teeth begin falling out around age 6 and usually finish by age 11.
Primary teeth, also known as baby teeth or milk teeth, usually fall out in the order in which they erupted. This means that the bottom front teeth are typically the first to go, followed by the top front. The next teeth to fall out are usually the lateral incisors, followed by the first molars, the canine teeth, and the rest of the molars, says HowStuffWorks. The exact order varies in different children, and this is normal.
