The first baby teeth to fall out are typically the two bottom front teeth (lower central incisors) and the two top front teeth (upper central incisors), followed by the lateral incisors, molars and canines. Molars typically fall out between ages 9 and 12 and are replaced by permanent teeth by about age 13.
KM,my DS has recently got two top and two bottom adult molars (his first molars I assume) and he has just turned 6 but still has his baby molars as well; the new ones have filled up the gap at the back of his gums. Of his baby teeth, only one of the bottom incisors has fallen out so far and new one not in yet.
