The 20 primary teeth in a baby's jaws are already present at birth, and they usually develop between the ages of 6 months and one year. By the age of three, most children have a complete set of 20 main teeth. This baby teeth eruption chart shows the order in which teeth emerge and the ages at which you should expect certain teeth to emerge. Every child is different, but the first teeth normally appear at the top and bottom front of their mouth. For more details please contact us! 8527366803
