Two-Phase Treatment

Two-Phase Orthodontic Treatment

At what age should you bring your child in for a bite and teeth alignment evaluation?

According to the American Association of Orthodontists, children should have their first orthodontic assessment by the age of 7. At this age, some permanent teeth have erupted, allowing Dr. Mohamed Aljanabi to identify potential bite or spacing problems early. Early evaluation in Brooklyn or Staten Island allows us to intercept jaw growth issues before they become more complex.

Two-phase orthodontic treatment is designed to reduce overall active treatment time and cost. It combines tooth alignment and facial physical changes to create a healthy bite and a beautiful smile.

Understanding the Two Phases

Phase I: Early Interceptive Treatment

Phase I begins while a child still has a mix of baby teeth and adult permanent teeth—typically between ages 7 and 11. The goal of Phase I is to guide jaw development to create enough room for all permanent teeth to erupt properly and ensure upper and lower jaws fit together correctly.

During Phase I, Dr. Aljanabi will take diagnostic records (photos, digital X-rays, and bite impressions) to create a tailored plan. Common Phase I appliances include jaw expanders, space maintainers, or specialized braces. Intercepting issues at this age prevents severe crowding and reduces the likelihood of tooth extractions later in life.

Rest Interval

After Phase I is complete, there is a resting period while the remaining permanent teeth erupt. Any active appliances from Phase I are removed or adjusted. During this rest phase, patients visit our Brooklyn or Staten Island office every six months for routine observation visits to monitor tooth eruption and jaw growth.

Phase II: Comprehensive Alignment

Phase II begins once all permanent teeth have erupted, usually around ages 11 to 14. In Phase II, Dr. Aljanabi places full upper and lower braces (or clear aligners) to move each tooth into its ideal position for optimal aesthetics and functionality.

Once Phase II is completed, retainers are provided to preserve your child’s new smile and prevent teeth from shifting back.

Why Early Treatment Matters

Deferring interceptive treatment when a child needs it can result in more severe malocclusions, requiring complex surgical or invasive procedures later in adulthood. Investing in early evaluation helps protect your child’s long-term oral health and confidence.
