Explore tooth eruption, dental development, and oral health milestones from infancy through adulthood.
Children usually develop 20 primary teeth. Eruption generally starts around 6 months and concludes by age 3. These teeth are crucial for chewing, speech development, and holding space for permanent teeth.
Adults typically have 32 permanent teeth. The transition (mixed dentition) starts around age 6 with the eruption of the first permanent molars and loss of primary lower incisors.
