The process of tooth development, or odontogenesis, typically takes several months to years, depending on the type of tooth. For children, primary teeth usually begin to erupt between 6 months and 1 year of age, with full eruption often completed by age 3. In adults, permanent teeth can take longer, with molars sometimes not fully erupting until the late teens or early twenties. Therefore, the timeline for a tooth to grow from a developing stage to being "half-grown" varies significantly based on age and tooth type.
