What Are Orthodontia Services? Types and Coverage

Orthodontia services are the dental treatments focused on diagnosing and correcting misaligned teeth and jaws. While most people associate orthodontics with straightening crooked teeth, the field covers a much wider range of services, from diagnostic imaging and bite correction to jaw growth guidance in children and long-term retention after treatment. These services address both cosmetic concerns and functional problems like difficulty chewing, speech issues, and jaw pain.

What Orthodontia Actually Treats

The core purpose of orthodontic treatment is correcting malocclusion, which is the clinical term for a “bad bite.” This includes overbites, underbites, crossbites, and open bites, along with crowded, gapped, or crooked teeth. These aren’t just appearance issues. Misaligned teeth are harder to clean, which raises your risk of cavities and gum disease over time. Teeth that don’t meet properly also wear down unevenly, and bite problems can contribute to TMJ disorder, the painful condition affecting the jaw joint.

Proper alignment improves chewing and speech function. For people with skeletal malocclusions, where the upper and lower jaws don’t line up correctly, orthodontic services can address the underlying jaw positioning rather than just moving individual teeth.

Diagnostic Services

Before any treatment begins, orthodontists use a combination of imaging tools to map your teeth, jaw, and surrounding structures. Traditional panoramic X-rays show a broad view of all your teeth and jawbone in a single image. Cone beam computed tomography (CBCT) goes further, generating a detailed three-dimensional image of your teeth, jaw, nerves, and surrounding tissue. Digital impression systems have largely replaced the old putty molds, using a handheld scanner to create a precise 3D model of your teeth in minutes.

These diagnostic records form the basis of your treatment plan. Your orthodontist uses them to identify the specific type of malocclusion, measure how far teeth need to move, and determine whether jaw correction is needed alongside tooth movement.

Types of Braces and Aligners

The most familiar orthodontic service is the fitting and management of braces or aligners. Several options exist, each suited to different clinical needs and patient preferences.

  • Traditional metal braces use stainless steel brackets bonded to each tooth, connected by a wire that applies gradual pressure. They remain the most versatile option for complex cases.
  • Self-ligating braces work similarly but use a built-in clip instead of elastic bands to hold the wire. This can reduce friction and may mean fewer adjustment visits.
  • Ceramic braces function like metal braces but use tooth-colored or clear brackets, making them less noticeable.
  • Lingual braces are bonded to the back surfaces of the teeth, hiding them completely from view. They’re more difficult to adjust and aren’t suitable for every case.
  • Clear aligners are removable, transparent plastic trays custom-molded to your teeth. You swap to a new set every one to two weeks as your teeth shift. Brands like Invisalign and ClearCorrect are the most widely used in orthodontic offices.

Your orthodontist will recommend a specific type based on the complexity of your case, your age, and how much correction is needed. Clear aligners work well for mild to moderate crowding and spacing, while metal braces are often better for severe bite problems or cases requiring significant tooth movement.

Specialized Jaw Correction Appliances

Some orthodontic problems go beyond tooth positioning and involve the jaw itself. Orthodontists use specialized appliances to guide jaw growth or reposition the jaw, particularly in children and adolescents whose bones are still developing.

A Herbst appliance, for example, is a fixed device anchored to the upper and lower molars that gently pushes the lower jaw forward. It’s commonly used for children with a significant overbite caused by a recessed lower jaw. Headgear, which attaches to the braces and wraps around the back of the head, can slow or redirect upper jaw growth. Palatal expanders widen a narrow upper jaw by applying outward pressure on the molars, creating more room for crowded teeth. These devices are most effective during growth spurts, which is one reason early evaluation matters.

Orthodontic Services for Children

The American Association of Orthodontists recommends that children have their first orthodontic evaluation no later than age 7. At that age, kids have a mix of baby and permanent teeth, and an orthodontist can spot developing problems early enough to intervene.

Phase 1 treatment, also called interceptive orthodontics, typically begins between ages 7 and 10. It addresses problems that are better corrected while the jaw is still growing, such as a narrow palate, severe crowding, or a crossbite. Common Phase 1 services include expansion appliances, headgear, functional appliances like the Herbst, limited braces on selected teeth, and space maintainers that hold gaps open for permanent teeth that haven’t come in yet. This phase usually lasts nine to twelve months.

After Phase 1 ends, most children enter a resting period. That break gives the jaw and teeth time for natural growth and allows remaining permanent teeth to erupt. Phase 2, or comprehensive treatment, begins later when most or all permanent teeth are in. This is the full braces or aligner phase that completes the alignment.

The Retention Phase

Treatment doesn’t end when braces come off or you finish your last aligner tray. The retention phase is a distinct orthodontic service designed to keep your teeth in their new positions. Without a retainer, teeth naturally drift back toward their original alignment, sometimes within months.

There are two main categories of retainers. Fixed retainers consist of a thin wire bonded behind your upper or lower front teeth (or both). They stay in place permanently and are especially useful for patients who had a large gap between their front teeth. Removable retainers come in two styles: Hawley retainers, which combine a stainless steel wire with an acrylic plate that rests against the roof of your mouth, and Essix retainers, which are transparent plastic trays similar to clear aligners.

Most orthodontists recommend wearing a removable retainer continuously at first, then transitioning to overnight wear. Current orthodontic guidance suggests that most patients need to wear some type of retainer indefinitely to maintain results. You’ll need to brush removable retainers daily, take them out before eating, and avoid certain drinks while wearing them.

How Insurance Covers Orthodontia

Insurance coverage for orthodontic services depends heavily on whether the treatment is classified as medically necessary or cosmetic. Many dental insurance plans include an orthodontic benefit, but it typically covers only a portion of the total cost, often with a lifetime maximum.

Government insurance programs tend to draw a sharper line. Medicaid programs, for instance, generally cover orthodontic treatment only for severe malocclusions, craniofacial anomalies, or cleft lip and palate, and only for patients age 20 and younger. Purely cosmetic orthodontic treatment is usually excluded. To qualify, an orthodontist must submit clinical documentation establishing medical necessity, and prior authorization is typically required before treatment begins.

Private insurance varies widely. Some plans cover a flat percentage of treatment, others provide a set dollar amount, and many have waiting periods before orthodontic benefits kick in. If your plan includes orthodontic coverage, check whether it applies to both children and adults, since some policies limit benefits to patients under 18 or 19.

Typical Treatment Timeline

For most adolescents and adults in comprehensive treatment, the active phase (wearing braces or aligners) lasts 12 to 24 months, though complex cases can take longer. Phase 1 treatment for children is shorter, usually nine to twelve months, followed by a monitoring period before Phase 2 begins. Adjustment visits during active treatment are typically scheduled every four to eight weeks, where wires are tightened, new aligner trays are issued, or appliances are modified. The retention phase, as noted, continues indefinitely in some form after active treatment wraps up.
