Ask most parents when they should first bring their child to an orthodontist and the answer is somewhere between "when the adult teeth come in" and "when the dentist says something needs to be done." Both answers are reasonable — and both arrive later than the American Association of Orthodontists recommends.
The AAO's guideline is age seven. Not because most seven-year-olds need orthodontic treatment, but because age seven is when the mix of primary and permanent teeth makes a trained orthodontist able to identify the conditions that benefit most from early intervention — and distinguish them from the conditions that are best left alone until full eruption.
At Laredo Orthodontics on Calton Road — the first and longest-serving orthodontic practice in Laredo, founded in 1985 — Dr. Catalina Zambrano offers complimentary first consultations specifically so that families can have this evaluation without any barrier. Most consultations result in a simple recommendation to monitor and return when more teeth have erupted. But the ones that identify a genuine Phase 1 indication are the ones that save patients years of more complex treatment — and sometimes spare them from procedures that would have been necessary had the condition been left unaddressed.
What Phase 1 Treatment Is — and What It Isn't
Phase 1 orthodontic treatment, sometimes called early or interceptive orthodontics, is treatment that occurs while the child still has a mix of primary and permanent teeth — typically between ages seven and ten. It is not a full orthodontic course. It addresses specific structural or developmental issues that are most effectively corrected while the jaw is still growing and more responsive to guidance.
Phase 1 treatment is followed by a rest period, then Phase 2 — full comprehensive orthodontic treatment once all permanent teeth have erupted, typically in the early teen years. The goal of Phase 1 is not to complete orthodontic treatment, but to create the conditions in which Phase 2 is simpler, faster, and produces a better long-term result. In some cases, it makes the difference between a Phase 2 case that requires extractions and one that doesn't.
Conditions That Benefit From Early Intervention
Not every orthodontic problem benefits from early treatment. The skill of the Phase 1 evaluation is in distinguishing those that do from those that don't, and recommending monitoring and waiting for the conditions that are best addressed comprehensively in Phase 2.
The conditions that do benefit from early intervention include:
- Crossbite: When upper teeth close inside lower teeth — either in the front or the back — the jaw is deflected from its natural growth path with every bite. Over time, this produces asymmetrical jaw development that becomes harder to correct without surgical intervention if left unaddressed. A palatal expander or similar appliance in Phase 1 corrects the crossbite while the suture in the palate is still responsive to expansion, before the bone has fused.
- Severe crowding: When jaw space is dramatically insufficient for the permanent teeth that are developing, Phase 1 expansion can create space that allows the permanent teeth to erupt in better alignment — reducing or eliminating the need for extraction-based orthodontic planning in Phase 2.
- Underbite: When the lower jaw protrudes in front of the upper jaw, the earlier the intervention, the better the outcome. Growth modification appliances can guide jaw development when growth is still actively occurring in a way that is simply not possible once growth is complete.
- Protruding upper front teeth: Significantly protruding front teeth are at elevated risk for traumatic injury. Early correction reduces that risk while also creating better jaw relationships.
- Prolonged habits affecting development: Thumb or finger habits, tongue thrust patterns, and prolonged pacifier use can alter the shape of the developing dental arches. Early identification and intervention — sometimes with habit appliances — addresses these before permanent changes become established.
What the Evaluation Involves
The Phase 1 evaluation at Laredo Orthodontics is a clinical examination and, when indicated, panoramic and cephalometric X-rays that give Dr. Zambrano a three-dimensional picture of the developing dentition, the jaw relationships, and the path the teeth are tracking. She evaluates tooth eruption sequence, jaw size and relationship, bite, and any developing crowding or spacing patterns.
Dr. Zambrano earned her dental degree from Tecnologico de Monterrey, graduating at the top of her class, before completing a one-year orthodontic internship and then a full Master of Science and Certificate of Orthodontics from UT Health San Antonio. She is a board-certified orthodontist and an active member of the American Association of Orthodontists, the American Dental Association, and the Texas Dental Association. Her preference for evidence-based treatment planning means that Phase 1 recommendations at Laredo Orthodontics are made when the clinical evidence supports early intervention — not as a default.
Why Summer Is the Practical Window
Summer in Laredo creates a specific practical advantage for the Phase 1 consultation and, if treatment is indicated, for beginning it. The Laredo heat keeps many families close to home and air conditioning, and the school-year schedule that makes appointments difficult to coordinate without missing class disappears entirely.
For a child who needs Phase 1 treatment involving an expander or other appliance, the adjustment period — the first few weeks of adapting to wearing a new appliance, speaking differently, managing the device — happens during a period when no teacher will notice, no school photo will capture it, and the child has the full flexibility of summer to build the habit.
For families simply coming in for the complimentary evaluation and leaving with a monitoring recommendation, the fifteen-minute appointment in June is a completely stress-free addition to the summer calendar.
Schedule the Complimentary Consultation at Laredo Orthodontics
Laredo Orthodontics is located at 802 E. Calton Road in Laredo, Texas. The practice is open Monday through Friday from 8am to 5pm and serves patients throughout Laredo and the surrounding communities including Zapata, Los Arcos, and La Presa.
Call (956) 724-8391 or visit online to schedule the complimentary first consultation. If your child is seven or older and hasn't had an orthodontic evaluation, the summer is when that changes.
