TL;DR

• The AAO recommends a first orthodontic evaluation by age 7 — you don't need a referral or a visible problem to schedule one.
• 5 signs to watch for: mouth breathing, crossbite, early tooth loss, visible crowding by age 7–8, and difficulty chewing.
• Early treatment addresses issues while jaw bones are still growing — a window that closes as children approach puberty.
• Not every child needs treatment. Many evaluations end with monitoring, not intervention.
• Free evaluations are available at Morristown Braces — no referral required.

Most parents know braces are eventually coming. What's less obvious is whether their child's teeth are showing early warning signs that warrant action now — before all permanent teeth have come in. Early orthodontic treatment isn't right for every child, but for those who do need it, acting during the growth window makes a meaningful difference. Here are five signs worth knowing.

Sign 1: Your child breathes through their mouth

Mouth breathing is one of the most significant and most overlooked signs that a child may benefit from early orthodontic evaluation. When children breathe through their mouths habitually — especially during sleep — it often indicates that nasal breathing is restricted, which is frequently related to jaw development. A narrow upper jaw reduces space for nasal airflow. Over time, chronic mouth breathing affects jaw growth: the upper jaw tends to grow narrow and tall rather than wide, compounding the original problem and creating crowding for incoming permanent teeth. Related signs include snoring or noisy breathing, waking frequently or restless sleep, chronic tiredness despite adequate sleep, dark circles under the eyes, and difficulty focusing or a hyperactivity diagnosis.

Sign 2: You notice a crossbite

A crossbite is when one or more upper teeth bite inside the lower teeth instead of outside them. Crossbites are among the clearest indicators that early treatment is warranted — they don't self-correct and they do cause progressive damage. Consequences of an untreated crossbite include uneven jaw growth, uneven tooth wear, facial asymmetry that worsens over time, and increased treatment complexity if addressed later. A palatal expander is the most common early intervention and is most effective during the growth phase, before the palatal suture closes in early to mid adolescence.

Sign 3: Baby teeth were lost very early

Baby teeth act as placeholders for permanent teeth developing underneath. When a baby tooth is lost early due to decay, injury, or extraction, adjacent teeth often drift into that space. The permanent tooth trying to erupt later may come in crooked, impacted, or blocked. Early tooth loss is considered significant when it happens before the typical age of natural shedding. A space maintainer or early monitoring can prevent a more complex situation later.

Sign 4: Teeth are clearly crowded or crooked by age 7–8

If your child's permanent front teeth have already come in obviously crowded — overlapping, rotated, or pushed sideways — by age 7 or 8, that's a signal worth an orthodontic evaluation. Visible crowding this early often indicates the jaw doesn't have enough space for the permanent teeth coming in. In some cases, early intervention can guide jaw growth and create space without needing to extract permanent teeth later.

Sign 5: Your child has difficulty chewing or avoids certain foods

A child who struggles to bite into foods, chews primarily on one side, or avoids certain textures may have a functional bite issue. Functional bite problems cause joint and muscle strain over time, accelerate tooth wear, and affect jaw joint (TMJ) development if left unaddressed into adolescence and adulthood.

What happens at an early orthodontic evaluation

At Morristown Braces, a first evaluation takes 45–60 minutes. Dr. Gonchar personally examines the teeth, bite, and jaw, reviews a 3D digital scan, and gives you one of three answers: no treatment needed, monitoring recommended, or early treatment recommended with a clear explanation of cost and timeline. According to the American Association of Orthodontists, children who receive early evaluations often end up with simpler treatment overall.

Frequently Asked Questions

What age should my child first see an orthodontist?

The AAO recommends age 7. If any of the signs in this article are present — mouth breathing, crossbite, early tooth loss, visible crowding — scheduling before age 7 is appropriate. No referral is required. The evaluation is free at Morristown Braces.

What is Phase 1 early orthodontic treatment?

Phase 1 is orthodontic care for children ages 7–11 who still have a mix of baby and permanent teeth. Treatment goals are jaw guidance, space creation, crossbite correction, and airway improvement. Phase 1 typically takes 9–18 months. If Phase 2 is needed later, $1,500 from the Phase 1 fee is credited toward it.

What if I wait until my child has all their permanent teeth?

For most children, waiting is fine. But for children with crossbites, narrow jaws, or airway concerns, waiting means missing the window when intervention is simplest and least invasive. The only way to know which category your child falls into is an evaluation.

The bottom line

Most children won't show all five signs — and many who show one or two simply need monitoring. But if any of these patterns are familiar, they're worth a conversation with a board-certified orthodontist. The free evaluation at Morristown Braces takes less than an hour and ends with a clear answer about what, if anything, to do.
