These <u>are the first teeth to erupt into the oral cavity</u>. The primary dentition is comprised of 20 teeth. Often these teeth are referred to as deciduous teeth.
These teeth will be exfoliated (lost) as the <u>permanent teeth </u>erupt.Primary teeth, also known as our milk teeth or deciduous teeth erupts first at the age of 6 to 7 months old and would usually completely erupt by around the age of 3, in time for a child's facial bone and jaw to grow. Permanent teeth start replacing the primary teeth at about 6 to 7 years old.
