The timing of interceptive orthodontic screening is best at around seven years old because this is when a child begins mixed dentition, providing enough dental and early skeletal information to predict future occlusion. At seven, eruption of the first permanent molars and incisors is occurring, which lets you assess arch length, crowding, and potential crossbite or bite discrepancies, while also gauging jaw growth trajectories. This window allows early, targeted measures—such as space maintenance after premature loss of primary teeth, guiding eruption with appliances, or initiating expansion for developing transverse problems—that can simplify or shorten future treatment and improve outcomes. Screening earlier, like at five, often yields less reliable information for planning, while waiting until about nine or eleven can make some interceptive opportunities less effective because growth and eruption patterns are already more advanced.
