Types of Facial Asymmetry: Causes, Symptoms & Treatment Options
Facial asymmetry refers to differences between the left and right sides of the face. While minor asymmetry is normal and found in almost everyone, significant facial imbalance may be caused by underlying skeletal, soft tissue, or functional issues.
The three primary types of facial asymmetry are:
- Skeletal Asymmetry – caused by uneven facial bone development
- Soft Tissue Asymmetry – caused by differences in muscles, fat, or facial tissues
- Functional Asymmetry – caused by bite problems, jaw movement issues, or muscle imbalances
Understanding which type of facial asymmetry you have is essential because treatment varies depending on the underlying cause.
At Dr. Gowds Dental Hospitals, advanced facial analysis, digital imaging, orthodontic evaluation, and multidisciplinary treatment planning help identify the root cause of facial asymmetry and determine the most effective treatment approach.
Is Facial Asymmetry Normal?
Yes.Most people have minor differences between the two sides of their face.
Examples include:
- One eyebrow sitting slightly higher
- One eye appearing larger
- Slight differences in cheek contours
- Small variations in jaw shape
These differences are generally harmless and do not require treatment.
Problems arise when asymmetry becomes significant, progressive, or associated with bite problems, jaw pain, speech difficulties, or aesthetic concerns.
The Three Main Types of Facial Asymmetry
Understanding the classification of facial asymmetry helps determine the most appropriate treatment plan.
Skeletal Asymmetry
Skeletal asymmetry occurs when the underlying facial bones develop unevenly.
This is often considered the most significant type of facial asymmetry because the imbalance originates from the facial skeleton itself.
How Skeletal Asymmetry Affects the Face
The condition may involve:
- Upper jaw (maxilla)
- Lower jaw (mandible)
- Chin
- Cheekbones
- Facial midline
When these structures develop unevenly, visible facial imbalance can occur.
Common Signs of Skeletal Asymmetry
- Crooked chin
- Uneven jawline
- One side of the face appears longer
- Facial midline deviation
- Uneven facial proportions
- Asymmetrical smile
Causes of Skeletal Asymmetry
Genetics
Inherited growth patterns can influence facial development.
Uneven Jaw Growth
One side of the jaw may grow more than the other during adolescence.
Congenital Conditions
Certain developmental disorders can affect facial bone formation.
Facial Trauma
Fractures or injuries may alter facial symmetry.
Growth Disturbances
Abnormal growth of facial bones can create long-term asymmetry.
Treatment Options for Skeletal Asymmetry
Treatment depends on severity.
Options may include:
- Orthodontic treatment
- Growth modification therapy
- Orthognathic surgery
- Combined orthodontic and surgical correction
At Dr. Gowds Dental Hospitals, CBCT imaging and digital treatment planning help accurately diagnose skeletal asymmetry and determine the most effective treatment pathway.
Soft Tissue Asymmetry
Soft tissue asymmetry occurs when the imbalance is caused by differences in facial muscles, fat distribution, skin thickness, or soft tissue volume rather than the underlying bones.
In many cases, the facial skeleton may be completely symmetrical.
How Soft Tissue Asymmetry Affects Appearance
The face may appear uneven because of differences in:
- Facial fat distribution
- Muscle size
- Skin elasticity
- Facial volume
Common Signs of Soft Tissue Asymmetry
- One cheek appears fuller
- Uneven facial contours
- Lip asymmetry
- Different facial volume on each side
- Uneven smile appearance
Causes of Soft Tissue Asymmetry
Natural Development
Some individuals naturally develop slight soft tissue differences.
Aging
Volume loss occurs differently on each side of the face.
Weight Changes
Fluctuations in body weight can affect facial symmetry.
Previous Injuries
Soft tissue damage may alter facial appearance.
Facial Muscle Imbalance
Overuse or underuse of facial muscles can create asymmetry.
Treatment Options for Soft Tissue Asymmetry
Depending on the cause, treatment may involve:
- Facial fillers
- Fat grafting
- Muscle therapy
- Cosmetic facial procedures
- Facial rehabilitation
Accurate diagnosis is important because soft tissue asymmetry requires a different approach from skeletal asymmetry.
Functional Asymmetry
Functional asymmetry occurs when the face appears uneven because of abnormal jaw function, bite discrepancies, or muscle activity.
The facial bones may be normal, but the way the jaw functions creates visible imbalance.
How Functional Asymmetry Develops
When the jaw shifts during movement or chewing, facial muscles may compensate unevenly.
Over time, this can make the face appear asymmetrical.
Common Signs of Functional Asymmetry
- Jaw shifts while opening or closing
- Uneven bite
- Facial imbalance during chewing
- TMJ discomfort
- Uneven smile
- One side of the jaw works harder than the other
Causes of Functional Asymmetry
Crossbite
Improper bite alignment may force the jaw into an abnormal position.
Malocclusion
Poor bite relationships can affect facial balance.
TMJ Disorders
Jaw joint dysfunction often contributes to asymmetry.
Teeth Grinding
Chronic grinding can alter muscle development.
Missing Teeth
Tooth loss can change bite mechanics and jaw positioning.
Habitual One-Sided Chewing
Repeated use of one side may create muscular imbalance.
Treatment Options for Functional Asymmetry
Treatment may include:
- Invisalign
- Orthodontic treatment
- Bite correction
- TMJ therapy
- Restorative dentistry
- Occlusal adjustment
At Dr. Gowds Dental Hospitals, functional asymmetry is evaluated using digital bite analysis and advanced orthodontic assessment.
Can Facial Asymmetry Be Corrected?
Yes. Many forms of facial asymmetry can be improved or corrected depending on the underlying cause.
Mild Cases
- Orthodontics
- Invisalign
- Cosmetic dentistry
- Bite adjustments
Moderate Cases
- TMJ therapy
- Orthodontic correction
- Restorative dental treatment
Severe Cases
- Orthognathic surgery
- Combined orthodontic-surgical treatment
- Comprehensive facial rehabilitation
The most effective treatment always depends on the type of asymmetry involved.
Final Thoughts
Facial asymmetry is common, and minor differences between the two sides of the face are completely normal.
However, noticeable facial imbalance may be caused by one of three primary conditions:
- Skeletal Asymmetry
- Soft Tissue Asymmetry
- Functional Asymmetry
Understanding the specific type of facial asymmetry is essential because each condition requires a different diagnostic and treatment approach.
If facial asymmetry affects your appearance, bite, jaw function, or confidence, a comprehensive evaluation at Dr. Gowds Dental Hospitals can help identify the cause and recommend the most appropriate treatment options.

Frequently Asked Questions
What are the three main types of facial asymmetry?
The three primary types are skeletal asymmetry, soft tissue asymmetry, and functional asymmetry.
Which type of facial asymmetry is most serious?
Skeletal asymmetry is often considered the most significant because it involves the underlying facial bones and may require orthodontic or surgical correction.
Can Invisalign correct facial asymmetry?
Invisalign can improve facial asymmetry when the cause is related to bite problems, tooth alignment, or functional jaw discrepancies.
Is facial asymmetry always caused by jaw problems?
No. Facial asymmetry may result from skeletal differences, soft tissue imbalances, muscle activity, aging, trauma, or bite-related issues.
How do dentists diagnose facial asymmetry?
Diagnosis typically involves clinical examination, digital smile analysis, orthodontic assessment, X-rays, and CBCT imaging to determine the underlying cause.
