Osmosis video - Eruption of primary and permanent dentitions

Primary dentition - also known as baby teeth - erupt during the first 6 years of life. Permanent dentition - also known as adult teeth - begins to erupt around age 6 and is complete by age 12 to 13. The primary dentition is eventually lost and replaced by the permanent dentition. The eruption of primary and permanent teeth occurs in a predictable pattern, beginning with the front teeth and proceeding towards the back of the mouth. For most people, the first tooth to erupt is the lower central incisor (front tooth). The last tooth to erupt is typically the second molar, located at the back of the mouth.
