In the past, orthodontic treatment did not begin until around age 12-14. This is when all the permanent teeth are already erupted or very close to it. It was also common for your dentist to remove permanent teeth to correct the bite and allow for room for the final phase of tooth movement. Modern orthodontists now advocate a way to keep permanent teeth, with phased interceptive orthodontics. In phase I orthodontics, children are treated at much earlier ages (usually between age 7-11 years old) to take advantage of continuing growth. Patients at this age tend to be more receptive to, and compliant with treatment. Interceptive orthodontics allows for fewer teeth to be extracted and also allows for better end results. Most children who undergo Phase I interceptive treatment will likely need a second phase referred to as braces to complete their treatment.
