The sequence in which baby teeth are replaced by adult teeth varies for every child. However, the order in which teeth fall out is generally the same order in which they grew in.
Although variable, the sequence of tooth loss follows a similar pattern for many children. The bottom front middle incisors are likely to go first, followed by the two upper middle front teeth, and then the remaining incisors. Next to fall out are the first set of molars, canine teeth and remaining molars, but not necessarily always in this order. An adult tooth also may begin to emerge before the primary tooth has been lost. In this case, it is important that the baby tooth be removed so that the adult tooth can develop normally.
