Orthodontics is more than just braces and clear aligners. Behind every beautifully straightened smile is a team of tools working together to guide your teeth into their ideal positions. These tools are known as orthodontic appliances — and they play a critical role in treatment plans for patients of all ages.
Whether you're currently in treatment, preparing to begin, or just exploring your options, understanding how these appliances work will help you feel more confident and informed throughout your orthodontic journey.
Let’s explore what orthodontic appliances are, the types most commonly used in modern care, what they're used for, and how to care for them properly.
What Are Orthodontic Appliances?
Orthodontic appliances are specially designed devices used by orthodontists to correct dental alignment, jaw position, bite irregularities, or other structural issues of the mouth and face. Some are fixed in place (meaning they stay in the mouth for a set period), while others are removable and worn during specific hours of the day.
While braces and aligners are among the most well-known orthodontic appliances, there are many others that play equally important roles — especially in complex or early orthodontic cases.
Why Orthodontic Appliances Are Used
Orthodontic appliances are used for a wide range of treatment purposes, including:
- Guiding jaw growth in children and teens
- Creating space for crowded teeth
- Helping adult teeth erupt properly in younger patients
- Correcting overbites, underbites, and crossbites
- Preventing harmful oral habits like thumb-sucking
- Holding teeth in place after active orthodontic treatment
- Addressing airway or tongue posture concerns
Each appliance has a specific function based on the needs of the individual patient. Often, these tools are used in combination with braces or aligners to improve treatment results or speed up progress.
Common Types of Orthodontic Appliances
Depending on your treatment plan, your orthodontist may recommend one or more of the following appliances.
Palatal Expander
Used primarily in children and teens, this device gradually widens the upper jaw to make more room for teeth and improve bite alignment. It's commonly used before braces to avoid the need for extractions.
Carriere® Motion Appliance
A sleek appliance that addresses bite correction early in treatment. It’s especially useful for Class II or Class III bite issues and helps reduce the need for headgear or surgery.
MARA Appliance (Mandibular Anterior Repositioning Appliance)
This fixed appliance helps guide the lower jaw forward, often used for patients with a retrusive lower jaw. It can improve facial balance and bite without surgical intervention.
Tongue Crib
Used to correct tongue thrusting or thumb-sucking habits, the tongue crib discourages incorrect tongue posture and promotes proper swallowing technique.
Space Maintainers
If a child loses a baby tooth prematurely, a space maintainer can preserve the gap until the permanent tooth is ready to erupt, preventing crowding or misalignment.
Separators
Also called spacers, these are small elastic rings placed between molars to create enough space for orthodontic bands used in braces.
Rubber Bands (Elastics)
Often worn with braces or aligners, rubber bands apply targeted pressure to correct bite alignment. They're removable but must be worn consistently for effectiveness.
Retainers
After treatment ends, retainers help hold your new smile in place. They can be fixed (bonded behind teeth) or removable (worn during certain hours).
How to Care for Your Orthodontic Appliances
Caring for your appliances is key to getting the best results. Here are some general guidelines that apply to most devices:
Cleaning and Maintenance
- Brush daily — Just like your teeth, appliances collect bacteria and debris. Brush them carefully with a soft toothbrush and mild soap or toothpaste.
- Avoid damage — Keep removable appliances in a protective case when not in use. Avoid chewing on pens, ice, or hard foods that could damage fixed appliances.
- Follow your schedule — Wear removable devices as instructed. Skipping time can delay your treatment or reduce its effectiveness.
Eating With Appliances
Some appliances — like expanders or tongue cribs — can make eating a little tricky at first. Stick with soft foods while you adjust, and avoid sticky or crunchy snacks that could dislodge or damage the device.
Oral Hygiene Tips
Maintaining good oral hygiene is especially important while wearing any appliance. Food can become trapped, increasing the risk of cavities or gum issues. Floss carefully around fixed appliances and use an oral irrigator if recommended by your orthodontist.
What to Expect When Wearing an Appliance
Like any change to your mouth, new appliances can come with an adjustment period. It’s normal to experience some of the following:
- Mild soreness or pressure for a few days
- Changes in speech (especially with tongue cribs or expanders)
- Altered eating habits
- A learning curve for cleaning and care
These side effects typically fade as your mouth adapts. If discomfort persists or you notice anything unusual, it’s important to reach out to your orthodontist for guidance.
Are Orthodontic Appliances Just for Kids?
Not at all. While many appliances are designed with growing jaws in mind, others are used for adult treatment as well. For example:
- Retainers and rubber bands are common for patients of all ages
- MARA and Carriere® appliances can help avoid jaw surgery in adults with bite concerns
- Tongue cribs may be used to treat persistent oral habits or support airway health
Appliance use is based on treatment goals — not age.
The Bigger Picture — Appliances Support Long-Term Results
Orthodontic appliances aren’t always the most visible part of your treatment, but they often play a behind-the-scenes role in achieving lasting results. Whether they’re guiding jaw growth, making room for teeth, or fine-tuning bite alignment, these tools support a healthier, more stable outcome.
The key is following instructions, maintaining good hygiene, and communicating with your orthodontic team if issues arise. When used properly, appliances can shorten treatment time, reduce the need for extractions, and deliver a more functional, confident smile.
