What Is a Narrow Upper Jaw? Its Relationship With Sports Performance, Breathing and Jaw Development in Children
Prof. Dr. Mehmet Oğuz Öztoprak’s functional jaw orthopaedics and sports dentistry approach.
Many parents view orthodontic problems only as crowded teeth. However, jaw development is not only an aesthetic issue. The jaws are closely related to:
- Breathing
- Chewing
- Speech
- Sleep quality
- Posture
- Balance mechanisms
- Facial development
Especially in children in the growth and development period, the development of the upper jaw can play an important role in terms of the airway and breathing functions. For this reason we have to ask: Is a narrow upper jaw only an orthodontic problem, or could it be part of a broader functional picture?
What Is a Narrow Upper Jaw?
The upper jaw (maxilla), located at the centre of the facial skeleton, is not only a bone that carries the teeth but also an important structure related to facial development and the respiratory system. In some children the upper jaw can develop narrower than expected. In this case, the following findings may be seen:
- Crowding of the teeth
- Crossbite
- A high palate structure
- Narrowing of the nasal floor
- Imbalances in jaw development
Not every narrow upper jaw is of the same severity. However, in some individuals this can affect not only tooth alignment but also breathing functions.
A Narrow Upper Jaw Is Not Only a Dental Problem
In the traditional orthodontic approach, a narrow upper jaw has often been evaluated only as the cause of crowded teeth. Today, however, the upper jaw is known to be related to:
- The nasal airway
- Breathing functions
- Jaw development
- Facial development
- Sleep quality
- Postural balance
For this reason, a narrow upper jaw should be evaluated not only as an aesthetic or orthodontic problem but as an important component of the growth and development process. Especially in children in the developmental period, early evaluation can contribute to preventing some functional problems that may arise in later years.
The Upper Jaw and the Nose Are Not Separate Structures
Many people think of the nose and the jaw as independent structures. However, the upper jaw also forms the floor of the nasal cavity. For this reason, during the growth period there is an anatomical relationship between the development of the upper jaw and the nasal airway.
Some studies have reported that expansion of the upper jaw may have positive effects on nasal airflow. This is not seen in the same way in every individual. However, it is accepted that the development of the upper jaw is connected to the respiratory system.
Why Is It Important for Children Who Do Sports?
During sports, the body’s most basic need is to be able to use oxygen effectively. Nasal breathing:
- Filters the air
- Humidifies it
- Warms it
- Supports breathing efficiency
When a mouth-breathing habit develops in some children, the following can be indirectly affected:
- Exercise tolerance
- Sleep quality
- Daytime energy level
- Concentration
For this reason, in children who do sports, not only the muscle and joint system but also breathing functions should be evaluated.
Why Is Breathing the Foundation of Performance in Athletes?
An athlete’s performance is not determined by muscle strength alone. Adequate oxygen support is needed for the muscles to work. For this reason, in modern sports sciences the following are gaining increasing importance:
- Breathing capacity
- Sleep quality
- The recovery process
- Neuromuscular coordination
- Balance mechanisms
Especially in athletes in the developmental period, supporting nasal breathing is considered important for healthy growth and development. For this reason, in children who do sports, not only the training programme but also the way of breathing is a factor that should be evaluated.
Is There a Relationship Between a Narrow Upper Jaw and Posture?
Some children who cannot breathe comfortably through the nose may change their head position over time. In particular, the following adaptations can develop:
- Forward head posture
- Increased load on the neck muscles
- Changes in shoulder position
- Postural adaptations
The aim of these adaptations is often to use the airway more comfortably. The human body constantly seeks balance. For this reason, changes in the respiratory system can sometimes also affect the postural system.
A New Perspective in Sports Dentistry
The traditional approach focused on tooth alignment for many years. Today, sports dentistry and functional orthodontics have begun to evaluate the relationships between:
- Breathing
- The airway
- Jaw development
- Posture
- Balance mechanisms
- Jaw joint functions
This approach is especially important for athletes in the growth period.
Why Is Functional Jaw Orthopaedics Different?
Functional jaw orthopaedics is not an approach that focuses only on tooth alignment. In this approach, the aim is to evaluate the following together:
- Jaw development
- Breathing functions
- The airway
- The muscle system
- The jaw joints
- Posture
Because jaw structures that develop during the growth period can affect not only the inside of the mouth but the entire craniofacial system. For this reason, when planning treatment in some children, not only how the teeth are aligned but also how the child breathes and grows should be taken into account.
Prof. Dr. Mehmet Oğuz Öztoprak’s Approach
In our clinic, the evaluation of a narrow upper jaw is not done by looking only at crowded teeth. At the same time, the following are evaluated together:
- Nasal breathing
- Mouth breathing habits
- Airway structure
- Jaw development
- Occlusal relationships
- Jaw joint functions
- Posture and spinal balance
- Functional needs during sports activities
The aim is not only to correct the teeth, but to understand the child’s growth and development process from a functional perspective.
Conclusion
A narrow upper jaw is not always only an orthodontic problem. In some individuals it can be part of a broader picture related to breathing functions, airway development, posture and the overall functional system.
For this reason, especially in children who do sports and are in the developmental period, the development of the upper jaw should be evaluated not only from an aesthetic but also from a functional perspective. In our clinic, our approach is not only to correct tooth alignment, but to evaluate the child’s way of breathing, growth pattern, jaw development, posture and overall functional balance together.
Because sometimes the issue is not only how the teeth are aligned, but how the child breathes, how they grow and how the body’s overall balance system works.

Frequently Asked Questions
What is a narrow upper jaw?
The upper jaw (maxilla) is not just a bone that carries the teeth but an important structure related to facial development and the respiratory system. In some children the upper jaw can develop narrower than expected, which may show as crowding, crossbite, a high palate, narrowing of the nasal floor and imbalances in jaw development.
Is a narrow upper jaw only a dental problem?
No. The upper jaw is known to be related to the nasal airway, breathing functions, jaw and facial development, sleep quality and postural balance. For this reason a narrow upper jaw should be considered an important component of the growth and development process.
Is there a relationship between the upper jaw and the nose?
Yes. The upper jaw also forms the floor of the nasal cavity. Some studies have reported that expansion of the upper jaw may have positive effects on nasal airflow; however, this is not seen in the same way in every individual.
Why is it important in children who do sports?
Nasal breathing filters, humidifies and warms the air and supports breathing efficiency. When mouth breathing develops, exercise tolerance, sleep quality, daytime energy and concentration can be indirectly affected. For this reason, breathing functions should also be evaluated in children who do sports.
Does a narrow upper jaw affect posture?
Some children who cannot breathe comfortably through the nose may change their head position over time; forward head posture, increased load on the neck muscles and postural adaptations can develop. The aim of these adaptations is often to use the airway more comfortably.
What is functional jaw orthopaedics?
It is not an approach that focuses only on tooth alignment. The aim is to evaluate jaw development, breathing functions, the airway, the muscle system, the jaw joints and posture together, because jaw structures developing during growth can affect the entire craniofacial system.
