Final answer:
Primary dentition begins with the emergence of baby teeth at 6 months, transiting to permanent dentition from ages 6 to 12, ending with wisdom teeth. The transition phase includes changes in incisors, canines, and molars as part of the development of adult teeth.
Step-by-step explanation:
Transition from Primary to Permanent Dentition Deciduous teeth, also known as baby teeth, emerge around the age of 6 months, signifying the beginning of primary dentition. By the age of 6 to 12, the transition to permanent dentition occurs, where the 20 baby teeth are replaced by 32 adult teeth. This process generally concludes with the emergence of wisdom teeth later in adolescence or early adulthood.
Key Stages in Dental Development: Lateral incisors (12-15 months) First molars (12-16 months) Cuspids or canines (16-24 months) Second molars (24-32 months) The permanent teeth arrangement includes eight incisors used for biting, four cuspids for tearing, and the remaining teeth for grinding food.
