Hi June, There are 2 sets of teeth, 1. Primary 2. Secondary The trigger for tooth formation is based on genetics, and on the growth of the child. As the child grows, the growth of the teeth starts, and the tooth bud is formed. Once it is about to be complete, it starts resorbing the root of primary teeth, and then erupts defining the path of eruption. The teeth the singer was able to grow were not incisors, but canines. The X-ray you are talking about is an OPG, which shows all of the teeth plus mandible and maxilla. The teeth you are saying are waiting to erupt are not actually waiting to erupt... they are being formed, and once they r formed ... they will erupt ... unless they are impacted. thank you Dr. Shoaib
