Orthodontic headgear is an essential tool in modern orthodontics, often prescribed by orthodontists to address specific dental conditions that braces alone cannot correct. Although it may seem daunting to some, understanding its purpose and benefits can make the process less intimidating for patients and their families. In this article, we’ll delve into the various uses of orthodontic headgear, how it works, and why it might be a necessary part of your orthodontic treatment.
What Is Orthodontic Headgear?
Orthodontic headgear is a device used in conjunction with braces or other orthodontic appliances to correct specific dental and skeletal discrepancies. It typically consists of straps or bands that fit around the head or neck and are attached to braces via metal hooks or tubes. The primary function of headgear is to apply the necessary force to move teeth or alter the position of the jaw.
Types of Orthodontic Headgear
There are different types of orthodontic headgear, each designed to address specific orthodontic issues. The most common types include:
Cervical Pull Headgear:
Cervical pull headgear consists of a strap that goes behind the neck and is attached to the braces in the upper jaw. It is used primarily to correct an overbite by pulling the upper teeth and jaw backward.
High-Pull Headgear:
High-pull headgear uses straps that go over the top of the head. It’s designed to correct overgrowth of the upper jaw (maxilla) and can be used to treat open bites by controlling the growth of the upper jaw.
Reverse-Pull (Facemask) Headgear:
Also known as a facemask, this type of headgear is used to treat underbites. It works by pulling the upper jaw forward to align it with the lower jaw, thus improving the patient’s bite and facial profile.
What Is Orthodontic Headgear Used For?
Orthodontic headgear is used when braces alone are insufficient to correct certain dental or skeletal issues. Here are some key reasons why orthodontists might recommend headgear:
Correcting Severe Overbites and Underbites:
In cases of severe malocclusion, such as overbites and underbites, headgear provides the additional force needed to move the teeth and jaw into the correct position. Overbites occur when the upper teeth excessively overlap the lower teeth, while underbites occur when the lower teeth extend beyond the upper teeth. Headgear can effectively address these issues by altering the growth pattern of the jaw or by repositioning the teeth.

Controlling Jaw Growth:
For younger patients who are still growing, headgear can be used to guide the development of the jaw. By applying pressure in a specific direction, headgear can help the jaw grow in a more favorable way, preventing or reducing the severity of orthodontic problems later in life.
Creating Space in the Dental Arch:
In cases where there is crowding of the teeth, headgear can help create the necessary space in the dental arch. By pulling the upper molars backward, headgear can create more room for the front teeth to align properly.
Preventing or Reducing the Need for Extractions:
In some cases, headgear can be used as an alternative to tooth extractions. By guiding the teeth and jaw into the correct position, headgear can reduce the need to remove teeth to create space in the mouth.
Improving Facial Aesthetics:
Orthodontic headgear can also play a crucial role in improving facial aesthetics. By correcting severe bite issues and guiding jaw growth, headgear can enhance the overall appearance of the patient’s face, leading to a more balanced and attractive facial profile.
How Does Orthodontic Headgear Work?
Orthodontic headgear works by applying a continuous and consistent force to the teeth and jaw. This force stimulates the movement of teeth through the bone, allowing them to shift into their proper positions over time. Depending on the type of headgear, the force can be directed in different ways to achieve specific results.
Cervical Pull Headgear:
Cervical pull headgear applies a backward and downward force on the upper teeth and jaw. This helps to correct overbites by moving the upper molars back and allowing the lower jaw to catch up in growth.
High-Pull Headgear:
High-pull headgear applies an upward and backward force on the upper teeth and jaw. It is particularly effective in cases where the upper jaw needs to be restrained from growing too much, helping to prevent open bites and other related issues.
Reverse-Pull Headgear (Facemask):
Reverse-pull headgear applies a forward force on the upper jaw, encouraging it to grow and move forward. This type of headgear is essential in treating underbites, as it helps align the upper and lower jaws for a more functional bite and improved facial harmony.
Who Needs Orthodontic Headgear?
Orthodontic headgear is typically recommended for children and adolescents whose jaws are still growing. This is because the headgear can effectively guide the growth of the jaw, making it easier to correct severe bite issues early on. However, in some cases, adults may also require headgear, particularly if they have significant skeletal discrepancies that cannot be addressed with braces alone.
Children and Adolescents:
Young patients with severe overbites, underbites, or other jaw discrepancies may benefit from orthodontic headgear. By starting treatment early, orthodontists can take advantage of the patient’s growth to achieve optimal results.
Adults:
Although less common, adults may also be prescribed orthodontic headgear. In these cases, headgear may be used in conjunction with other orthodontic treatments to correct significant bite issues or to prepare the mouth for future dental procedures, such as orthognathic surgery.
The Benefits of Orthodontic Headgear
Although wearing orthodontic headgear may seem challenging, the benefits far outweigh the temporary discomfort. Some of the key benefits include:
Effective Correction of Severe Bite Issues:
Headgear is often the most effective way to correct severe overbites, underbites, and other skeletal discrepancies. By addressing these issues early on, patients can avoid more invasive treatments later in life.
Improved Facial Aesthetics:
By guiding the growth of the jaw and aligning the teeth, headgear can significantly improve the patient’s facial profile, leading to a more balanced and attractive appearance.
Reduced Need for Extractions or Surgery:
In some cases, headgear can prevent the need for tooth extractions or orthognathic surgery by creating the necessary space in the dental arch or by guiding jaw growth in a more favorable direction.
Long-Term Dental Health:
Correcting bite issues with headgear can lead to better long-term dental health. Properly aligned teeth are easier to clean, reducing the risk of cavities, gum disease, and other oral health issues.
Conclusion
Orthodontic headgear is a powerful tool in the hands of an experienced orthodontist. It offers a targeted approach to correcting severe dental and skeletal issues that braces alone cannot address. While wearing headgear may require some adjustment, the benefits it provides in terms of improved bite, facial aesthetics, and overall dental health are well worth the effort. For patients facing the prospect of headgear, understanding its purpose and following the orthodontist’s instructions closely will ensure the best possible outcome.
