Why Early Orthodontic Treatment Matters

The American Association of Orthodontists (AAO) recommends that children have their first orthodontic evaluation by age 7. At this early age, orthodontists can identify potential issues with dental development—even if no immediate treatment is needed. This proactive approach helps ensure that any problems are detected and addressed at the most optimal time for a child’s growth.

When parents hear the phrase early orthodontic treatment it can sound unnecessary. Many people think orthodontics is something that happens during the teenage years, and for most patients that is true. However, decades of orthodontic research and clinical experience have shown that certain problems are best treated early, while a child is still growing and teeth are still erupting. Early interceptive orthodontic treatment, often called Phase I treatment, is about recognizing specific conditions and correcting them at a time when growth allows the most effective and stable results.

Early orthodontic treatment is recommended for six primary reasons.

1. To prevent impactions and support normal tooth eruption. One of the most common reasons for early treatment is to help permanent teeth erupt naturally into the mouth. When jaws are too small or spacing is not maintained, teeth may remain trapped beneath the gums. Early orthodontic care can create space for proper eruption, reduce the risk of impacted teeth, decrease the likelihood of future extractions, and simplify later treatment.
2. For the correction of crossbites and harmful jaw shifting. Crossbites are more than a cosmetic concern. Posterior crossbites, especially on one side only, may cause a child to shift the jaw to one side when biting, altering growth direction and affecting facial symmetry. Anterior crossbites may cause or exacerbate developing underbite growth patterns. Orthodontic evidence supports early correction to guide jaw growth while its trajectory can be changed.
3. To address severe crowding early. Crowding rarely improves on its own. Early treatment may expand dental arches, preserve space for erupting teeth, and reduce the need for extractions later. Managing crowding early supports healthier alignment, healthy gums, and predictable long-term outcomes.
4. Airway concerns are an increasingly common reason for early treatment. Orthodontic expansion and arch development may support nasal breathing and proper tongue posture. Scientific evidence recognizes the role orthodontic growth guidance may play in overall airway development.
5. So that psychosocial concerns can be addressed. For some children, orthodontic concerns impact confidence and emotional well-being. Early correction can improve self-esteem and social comfort when dental appearance is a source of distress.
6. Thumb sucking or tongue thrusting habits can influence jaw growth and tooth position. Early orthodontic intervention, sometimes in collaboration with speech therapy professionals, helps reduce lasting effects of these and other habits.

Phase I treatment is focused and purposeful. Its goal is to correct problems early, reduce future complexity, and guide healthy growth. Not every child requires early treatment, but some do, and it is best to know this when treatment is most effective. An early orthodontic evaluation helps proactive parents make informed decisions based on established orthodontic evidence and standards of care.
