Orthodontics and Sinus Issues: Understanding the Connection

Orthodontics and Sinus Issues

Orthodontics plays a crucial role in aligning teeth and correcting dental issues, but did you know that it can also have an impact on sinus health? The relationship between orthodontic treatment and sinus issues is often overlooked, but it's essential to understand how these two are connected. In this blog post, we will explore the connection between orthodontics and sinus issues, common concerns, and how to ensure a well-informed and holistic approach to dental and sinus health.

The Nasal-Skeletal Connection:

The nasal cavity and the maxillary sinuses are located in close proximity to the upper jaw, also known as the maxilla. When the maxilla is moved or altered during orthodontic treatment, it can have implications for the sinuses.

Maxillary Expansion:

Maxillary expansion is a common orthodontic procedure used to widen the upper jaw to correct crowding or crossbites. This expansion can also lead to a slight widening of the nasal cavity, potentially improving nasal breathing in some cases.

Sinus Pressure:

In some instances, orthodontic appliances or pressure from braces can cause temporary discomfort or pressure in the sinuses. This is usually a transient issue and tends to resolve on its own as the body adjusts to the changes.

Allergy and Sinusitis Management:

Proper oral hygiene can be challenging with braces, leading to an increased risk of cavities and gum problems.

Some individuals with pre-existing sinus issues, such as allergies or sinusitis, may experience changes in symptoms during orthodontic treatment. It's essential to communicate any existing sinus conditions to your orthodontist for appropriate management.

Preventing Sinus Complications:

While orthodontic treatment can have minor effects on the sinuses, complications are rare when performed by qualified orthodontic professionals. Here are some tips to ensure a well-informed and holistic approach to dental and sinus health:


Openly communicate any pre-existing sinus conditions, allergies, or respiratory issues to your orthodontist before starting treatment. This information will help them tailor the treatment plan to your specific needs.

Regular Check-ups:

Attend regular check-ups with your orthodontist to monitor your progress and address any concerns promptly. If you experience persistent discomfort or sinus-related symptoms, inform your orthodontist immediately.

Allergy Management:

If you have allergies, work with both your orthodontist and allergist to manage symptoms effectively during orthodontic treatment. Controlling allergies can contribute to overall sinus health.

Nasal Breathing:

Proper nasal breathing is crucial for sinus health. Orthodontic treatment that improves jaw alignment can positively impact nasal breathing in some cases, leading to better sinus health.


Orthodontics and sinus health are interconnected, and understanding this relationship is essential for a comprehensive approach to dental care. While orthodontic treatment can have minor effects on the sinuses, it is generally safe and well-tolerated when performed by experienced professionals. Open communication with your orthodontist and appropriate management of pre-existing sinus conditions are key to ensuring a positive orthodontic experience and maintaining optimal sinus health.


Can orthodontic treatment cause sinus problems?

Orthodontic treatment, when performed by qualified professionals, is generally safe and unlikely to cause sinus problems. However, in some cases, temporary discomfort or pressure in the sinuses may occur due to the movement of the upper jaw. This typically resolves on its own as the body adjusts.

Will orthodontic treatment worsen my pre-existing sinusitis?

Orthodontic treatment is not known to worsen pre-existing sinusitis. However, it's essential to communicate any sinus conditions to your orthodontist before starting treatment. They can adjust the treatment plan to minimize potential impacts on sinus health.

Can orthodontic treatment improve nasal breathing?

In some cases, orthodontic treatment that involves maxillary expansion can lead to a slight widening of the nasal cavity, potentially improving nasal breathing. However, the extent of improvement varies from person to person and depends on individual factors.

Will wearing braces or aligners affect my ability to breathe through my nose?

Wearing braces or aligners should not affect your ability to breathe through your nose. However, some individuals may experience temporary adjustments as they adapt to the orthodontic appliances. If you notice any breathing difficulties, consult your orthodontist promptly.

Can orthodontic treatment help with sinus-related headaches?

Orthodontic treatment itself is not a direct treatment for sinus-related headaches. However, improving dental alignment and jaw positioning may indirectly contribute to reducing certain types of headaches associated with dental issues.
