When a tooth emerges from the gum tissue it is called eruption. This normally
happens at the age of 6 months. In most cases the first teeth to erupt are the mandibular
central incisors (lower), then the maxillary central incisors (upper) this usually happens
at the ages of 6 months to 12 months. The anterior portion of the mouth is the first to

neonatal tooth, in some cases the these are lost soon after birth. Tooth development
normally starts in the 3rd to 6th months of pregnancy.
