Phase Two orthodontic treatment typically begins once most or all of the permanent teeth have erupted, usually between the ages of 11 and 13. This stage is focused on perfecting the bite, aligning the teeth for proper long-term function, and achieving the desired aesthetic outcome. While Phase One targets early developmental issues such as jaw growth and spacing, Phase Two is designed to complete the orthodontic process using braces, clear aligners, or other appliances—delivering a healthy, confident smile that lasts a lifetime.
