  • Ya ya, it is normal to have 8 teeth in upper jaw and 8 teeth in lower jaw at two and a half years of age. Second baby molars will erupt in some time. Second baby molars usually erupt at 3 years of age. If the second baby molars don't erupt even after a year, then you can consult a pedodontist who is specialist in children dentistry.

  • There are 10 teeth in the lower jaw, 5 teeth on each side. There are 4 baby incisors, 2canines and 4 molars present in the lower jaw in kids. The front baby teeth usually erupt by age of 2 years and the back baby teeth usually comes by 3 years. All teeth may not erupt in case of partial anodontia in which there are one of more missing teeth present. You need to refer to a pedodontist for this that specializes in children dentistry. Pedodontist will take an x-ray to see whether other baby teeth are present or not.  Sometimes, due to some hindrance, the teeth don’t erupt. If baby teeth are not erupting due to some hindrance, then the pedodontist will do treatment for it but if the remaining baby teeth are not present in x-ray, then nothing can be done for it.  For more info on human dentition, you can refer to the following article.. http://www.identalhub.com/article_human-dentition-233.aspx
