Orthodontic appliances are devices that are used to correct misaligned teeth and other dental problems. They come in many different types, each with their unique features and benefits.

The following are the most common types of orthodontic appliances used in dental treatment:

1. Braces:

Braces are perhaps the most well-known and popular type of orthodontic appliance. They are made up of brackets, wires, and bands that are attached to the teeth to gently guide them into the correct position over time. There are several types of braces, including traditional metal braces, ceramic braces, lingual braces, and self-ligating braces.

2. Clear Aligners:

Clear aligners, also known as invisible braces, are a popular alternative to traditional braces. They are made of transparent plastic and are custom-made to fit your teeth perfectly. Clear aligners work by gradually shifting the teeth into the correct position over time. They are almost invisible, making them a popular choice for adults who are self-conscious about wearing braces.

3. Space Maintainers:

Space maintainers are orthodontic appliances that are used to keep the space between teeth open after a tooth has been extracted or lost prematurely. They are often used in young children whose permanent teeth have not come in yet. Space maintainers prevent the teeth from moving out of their proper positions and help ensure that the permanent teeth come in correctly.

4. Palatal Expanders:

Palatal expanders are used to widen a narrow upper jaw. They are typically used in children and teenagers while their bones are still growing. Palatal expanders apply gentle pressure to the upper jaw, which gradually expands the arch of the mouth and corrects overbites and crossbites.

5. Headgear:

Headgear is an orthodontic appliance that is worn outside of the mouth. It is typically used to treat overbites and underbites in children and teenagers. Headgear applies force to the teeth and jawbone, which helps to redirect the growth of the jaw and move the teeth into the correct position.

6. Retainers:

Retainers are appliances that are used to maintain the position of the teeth after orthodontic treatment. They are typically worn for a period of time to ensure that the teeth stay in their correct positions. There are several types of retainers, including removable retainers, fixed retainers, and clear retainers.


Orthodontic appliances are an effective way to correct dental problems and achieve a healthy, beautiful smile. There are many different types of orthodontic appliances available, each with their unique features and benefits. Your orthodontist can help determine which type of appliance is best suited for your specific needs and goals. With proper treatment, you can achieve the perfect smile you have always wanted.
