Does My Child Need Orthodontic Treatment? And When Should We Start?

The Answer

It is generally a good idea to schedule an orthodontic evaluation around the time your child’s permanent front teeth begin to erupt.

What Is Pediatric Orthodontics?

What Is Pediatric Orthodontics?

**Pediatric orthodontics refers to orthodontic care provided from early childhood, when the primary teeth begin to erupt, through the growing years and adolescence before adulthood. Treatment is generally divided into Phase I and Phase II orthodontics.**

Also known as children’s orthodontics, growth-phase orthodontics, or early orthodontic treatment, pediatric orthodontics goes beyond simply straightening teeth. It involves a detailed evaluation of the jaws, facial growth, and developing dentition. When clinically appropriate, treatment may guide, encourage, or modify growth to help the jaws and teeth develop in a healthier and more balanced direction.

Type

Early Interceptive Treatment (Phase I treatment)

Comprehensive orthodontic treatment OR Phase II treatment

Purpose

To guide the development of the teeth and jaws, address developing problems early, and make future comprehensive orthodontic treatment simpler when possible.

To address remaining tooth alignment and bite problems after most or all permanent teeth have erupted.

Timing

Phase I treatment is often considered during the mixed-dentition stage, typically between ages 6 and 10, when both primary and permanent teeth are present. The appropriate timing varies according to each child’s dental development and growth pattern.

Phase II treatment commonly begins after most permanent teeth have erupted, often between ages 11 and 15. The exact timing varies depending on each child’s growth and dental development.

Treatment

Treatment may include guiding jaw growth, preserving space for developing permanent teeth, protecting specific teeth, and addressing certain bite or growth problems at an early stage.

Comprehensive treatment typically uses orthodontic appliances such as brackets, wires, bands, or clear aligners to align the teeth and establish a more stable bite.

Guides Healthy Jaw Growth

02

Helps Address Protrusion

03

Corrects Harmful Oral Habits

04

Guides Proper Eruption of Permanent Teeth

05

Malocclusion & Oral Habit Checklist for Children

01

Frequently rests the chin on one hand

02

Has a thumb- or finger-sucking habit

03

04

Frequently bites the lower lip

05

Does My Child Need Phase I Orthodontic Treatment?

If your child shows any of the following dental or bite conditions, an orthodontic evaluation may help determine whether Phase I treatment should be considered.

Spacing

01

Spacing

Noticeable spaces between teeth may affect alignment and, in some cases, gum health.

02

Underbite

An underbite occurs when the lower teeth bite in front of the upper teeth. Early evaluation can help assess its effect on tooth wear and jaw development.

Underbite
Deep Bite

03

Deep Bite

A deep bite occurs when the upper front teeth excessively overlap the lower front teeth and may contribute to tooth or jaw discomfort in some cases.

04

Crossbite

A crossbite occurs when one or more upper teeth bite inside the lower teeth, which may interfere with normal bite function and jaw development.

Crossbite
Crowding

05

Crowding

Crowding occurs when there is not enough space in the dental arch for the teeth to align properly. It may make oral hygiene more difficult and affect the appearance of the smile.

06

Open Bite

An open bite occurs when the upper and lower teeth do not meet properly when the mouth is closed, which may affect chewing and speech.
