The first teeth erupt between 6 to 9 months. These are lower central incisors. The gums look a bit swollen for a few days, and then tiny white spot appears, which the tooth is. Over the next 3 – 4 months the teeth erupt with great rapidity the central pair, the upper central pair and then two more on each side in the lower and upper jaws – making a total of 8 incisors.
The entire set of 20 teeth erupts by the age of 2.5 years. These are primary teeth.
