Unfortunately, early orthodontic problems rarely resolve on their own. When a child’s jaw, bite, or tooth alignment is developing in the wrong direction, time is one of the most important factors in determining success. Phase I treatment, also called interceptive orthodontics, is designed to address these issues while the bones and soft tissues of the face are still actively growing, making correction more predictable and often reducing the complexity of later treatment.
At McCullum Orthodontics in Jeffersonville, IN, we offer comprehensive early intervention orthodontic services for children who show signs of developing bite or jaw problems. With advanced training from the University of Louisville and more than a decade of clinical experience, Dr. McCullum evaluates each child’s growth patterns carefully and recommends Phase I treatment only when it will meaningfully improve long-term outcomes.
The specific appliances and techniques used in Phase I treatment depend entirely on each child’s developing concerns. Dr. McCullum conducts a thorough evaluation before recommending any course of action, ensuring each patient receives only the treatment that is clinically appropriate for their growth stage. Common Phase I interventions include:
Palatal Expansion: A palatal expander works by gradually widening the upper jaw to create more space for permanent teeth and improve the relationship between the upper and lower arches. Dr. McCullum is trained in airway-focused expansion techniques that address not only alignment but also nasal airway capacity and breathing function.
Dentofacial Orthopedics: Growth modification appliances like facemask therapy for underbites and Herbst appliances for significant jaw discrepancies can guide the position and development of the facial bones and jaws. These interventions can reduce or eliminate the need for surgical correction in adulthood and are only effective during active skeletal growth.
Habit Correction and Space Maintenance: Prolonged thumb sucking, pacifier use, and tongue thrusting can alter palate and bite development. Dr. McCullum offers habit appliances to help children discontinue these behaviors at a stage when correction is still straightforward. When a baby tooth is lost prematurely, a space maintainer may be recommended to preserve space for the incoming permanent tooth.
Not every child needs Phase I treatment, and Dr. McCullum takes a conservative, individualized approach to recommendations. At McCullum Orthodontics, we advise that children have an orthodontic evaluation by age 7, when the first molars and incisors have typically erupted and growth patterns become easier to assess. Some conditions that may indicate a need for early intervention include:
Crossbites: Upper teeth that bite inside the lower teeth can cause jaw shifting and lead to asymmetric facial growth over time. Underbites: A lower jaw that protrudes ahead of the upper jaw is most effectively corrected during active skeletal growth, before the bones fully mature. Severe crowding: Insufficient space for permanent teeth to erupt properly can lead to impaction, misalignment, and the need for extractions later. Open bites: A gap between the upper and lower front teeth when the mouth is closed is often associated with tongue thrusting or prolonged thumb sucking habits. Airway concerns: A narrow palate or restricted nasal passages can impair a child’s ability to breathe through the nose, affecting sleep and overall health.
Identifying these patterns early gives Dr. McCullum more tools to work with and can prevent the need for more invasive interventions later. A free evaluation at McCullum Orthodontics is the right first step for any family with concerns about their child’s jaw or dental development.
Phase I treatment is not the end of orthodontic care — it is the foundation for it. After completing the first phase, patients enter a monitored rest period where Dr. McCullum tracks jaw growth and tooth eruption before determining whether and when Phase II treatment is appropriate. Phase II typically involves full braces or clear aligners once most or all permanent teeth have come in. Children who complete Phase I often require shorter, less complex Phase II treatment — and in some cases Phase II may not be necessary at all.
The goal of a two-phase approach is to distribute treatment across two growth periods, making each phase more focused and effective. Dr. McCullum personally monitors every patient through the transition between phases, adjusting the plan based on observed growth rather than using a one-size-fits-all timeline.
Dr. Heather McCullum graduated as valedictorian from the University of Louisville School of Dentistry, earned her DMD degree summa cum laude, and received the American Association of Orthodontists Award. She brings 14 years of clinical orthodontic experience to every patient evaluation, with a particular focus on early intervention and airway-focused orthodontics that sets McCullum Orthodontics apart from larger group practices in Southern Indiana.
