Twenty baby teeth are already forming before birth. An infant’s front four teeth usually erupt first, typically around 6-8 months of age, although, some children don’t have a first tooth appear until 12 months of age. After the eruption of the front four teeth, the remaining teeth typically appear “in pairs” along the sides of the mouth until the child is approximately 3 years of age. The pace and order of tooth eruption varies.
The first permanent teeth typically begin to erupt at about the age of 5 or 6 and include molars behind the back baby teeth, as well as front incisors. Some permanent teeth replace baby teeth, while others do not. This process of eruption continues until approximately the age of 14.
Don’t worry if it seems your child’s teeth are a few months early or late, as all children have different eruption patterns. The pattern (order in which teeth erupt) is more important than the exact time teeth come in.
