Phase 1 orthodontic treatment is early, targeted care for a child who still has some baby teeth, usually between about ages 7 and 10. Its goal is not a perfect smile. Instead, it corrects or guides a specific problem, such as a crossbite or severe crowding, while the jaws are still growing. Many children never need Phase 1 at all, and the American Association of Orthodontists (AAO) says an early checkup is the best way to find out.
February is Children’s Dental Health Month, a good reminder for parents in Yuba City, Lincoln, and throughout Sutter County to think about their child’s bite as well as their cavities. This guide explains how two-phase care works, what Phase 1 orthodontic treatment can address, and what to expect if your orthodontist recommends it.
Why the AAO Recommends a Checkup by Age 7
The AAO recommends that children have their first orthodontic checkup when a problem is first noticed, and no later than age 7. Around that age, most children have a mix of baby and permanent teeth, which lets an orthodontist see how the bite and jaws are developing. Age 7 is a deadline, not a starting gate, so you can come in earlier if something concerns you.
An early visit does not mean your child will get braces. After the exam, the orthodontist usually recommends one of three paths:
- No treatment needed right now
- Monitoring growth with periodic checkups
- Early treatment for a specific developing problem
What Two-Phase Treatment Means
Two-phase treatment splits orthodontic care into two separate stages with a rest period in between.
Phase 1: Early Treatment
Phase 1 happens while some baby teeth are still in place. It focuses on one or two specific goals, such as widening a narrow upper jaw, correcting a crossbite, or creating room for permanent teeth that are about to come in. Appliances may be fixed or removable, and treatment is usually shorter than full braces.
The Resting Period
After Phase 1, the remaining permanent teeth are allowed to come in naturally. During this time your orthodontist checks progress at regular visits. Some children wear a retainer, and some do not need any appliance.
Phase 2: Comprehensive Treatment
Once most permanent teeth are in, often in the early teen years, a second phase may be needed to fine-tune the position of every tooth and finish the bite. This phase usually uses braces or clear aligners. The AAO notes that a second phase may still be needed even after successful early treatment.
You can read how we approach this on our two-phase treatment page.
Problems Phase 1 Treatment Can Address
According to the AAO, early treatment can help intercept developing problems, guide jaw growth, and make room for incoming permanent teeth. Common reasons an orthodontist may suggest it include:
- Crossbites, where upper teeth sit inside the lower teeth
- Underbites, where the lower jaw sits ahead of the upper jaw
- Severe crowding or a lack of space for permanent teeth
- Large gaps, extra teeth, or missing teeth
- Thumb, finger, or pacifier habits that are affecting the bite
Some of these problems are easier to correct while a child is growing. Waiting can sometimes make correction harder later, which is why timing matters.
Signs Parents Can Watch For at Home
You do not need special tools to notice that something may be off. Consider an orthodontic check if your child has:
- Baby teeth lost very early or very late
- Trouble chewing or biting
- A jaw that shifts to one side when the mouth closes
- Front teeth that stick out or do not touch
- Crowded teeth as the first permanent teeth arrive
What to Expect During Phase 1
Phase 1 starts with a consultation and records, such as photos and X-rays, so the orthodontist can plan exactly what needs to change. Depending on the goal, your child may wear an appliance like a palatal expander, a partial set of braces, or a removable appliance. Visits are spaced out over the treatment period so the orthodontist can check progress and make adjustments.
Kids usually adapt quickly. It is common to feel pressure or mild soreness for a few days after an appliance is placed or adjusted. Soft foods and good brushing habits help a lot during this stage.
Is Early Treatment Right for Every Child?
No. The AAO is clear that early treatment is not meant for every child. Many kids are best served by simply monitoring growth and starting a single phase of treatment once their permanent teeth are in. An orthodontist will only recommend Phase 1 when there is a specific problem that benefits from early correction, and will explain why.
If you are unsure, ask the orthodontist what could happen if you wait, and what the plan would look like either way. A good recommendation should make sense to you as a parent.
Frequently Asked Questions
The AAO recommends a first orthodontic checkup when a problem is first noticed, and no later than age 7. Many children are simply monitored after that visit.
Not always. Phase 1 corrects specific problems early, but a second phase with braces or aligners may still be needed once all permanent teeth are in.
No. Parents can schedule an orthodontic checkup directly. You also do not need to wait until all the baby teeth have fallen out.
