An underbite occurs when the lower teeth extend beyond the upper teeth, creating an abnormal alignment that affects both function and appearance. Left untreated, an underbite can lead to various health issues, including jaw pain, headaches, difficulty chewing, and even speech problems. These symptoms not only disrupt daily comfort but may also lead to more severe complications over time, affecting oral and overall health.
Correcting an underbite brings significant benefits, offering lasting improvements in health, appearance, and quality of life for individuals and families alike. With advances in orthodontic care, registered orthodontists provide safe, effective solutions for underbites, helping to align the teeth and jaw for better function and well-being.
What is an Underbite?
An underbite is a type of dental misalignment where the lower teeth protrude beyond the upper teeth when the mouth is closed, often causing a visible misalignment of the jaw. This condition, formally known as “prognathism,” can vary in severity, from a slight overlap to a more pronounced extension that impacts daily activities like chewing, speaking, and even breathing.
Common Causes of Underbites
Several factors can contribute to the development of an underbite, often involving a mix of genetic, behavioural, and developmental influences.
- Genetics: Hereditary jaw structure is one of the most common causes of underbites. Family traits, such as larger lower jaws or certain dental structures, can increase the likelihood of an underbite, often passed down across generations.
- Childhood Habits: Prolonged behaviours in early childhood can also contribute to an underbite. Extended thumb-sucking, pacifier use, or bottle feeding beyond infancy places pressure on the developing teeth and jaw, encouraging the lower teeth to shift forward over time.
- Developmental Factors: In some cases, developmental differences in jaw growth patterns lead to underbites. If the upper and lower jaws grow at different rates or angles, it can result in an underbite. Certain medical conditions affecting bone growth may also contribute to jaw discrepancies that result in this type of misalignment.
Health Risks of Leaving an Underbite Untreated
An untreated underbite can lead to a variety of health complications, impacting both oral and overall well-being.
Dental Health Issues
- Increased Risk of Tooth Decay and Gum Disease: Misaligned teeth are harder to clean effectively, leading to plaque buildup and a higher risk of cavities and gum disease.
- Enamel Wear: Constant friction from misalignment wears down enamel, making teeth more vulnerable to decay and increased sensitivity.
Physical Discomfort
- Jaw Pain and TMJ Disorders: The strain on the jaw caused by an underbite can lead to temporomandibular joint (TMJ) issues, causing chronic jaw pain.
- Chronic Headaches: Tension from misaligned jaw muscles often results in frequent headaches.
- Difficulty Chewing and Digesting Food: An underbite can make thorough chewing difficult, which may affect digestion and nutrient absorption.
Speech Difficulties
An underbite can disrupt normal tongue positioning and mouth movement, contributing to speech impediments and making pronunciation more challenging.
Aesthetic and Psychological Impact
The visible impact of an underbite on facial structure can affect self-esteem and confidence, particularly in social settings, where appearance and ease of speaking play a key role.
Benefits of Correcting an Underbite for Kiwi Families
Improved Oral Health
Aligning teeth properly reduces the risk of decay, gum disease, and long-term dental issues. Improved alignment makes it easier to maintain good oral hygiene—especially important for children as they build lifelong habits around dental care.
Enhanced Comfort and Reduced Pain
Correcting an underbite can relieve chronic jaw pain, reduce TMJ-related issues, and lessen associated headaches. Better alignment also improves chewing efficiency, aiding digestion and providing greater comfort when eating.
Better Speech and Confidence
Underbite correction can result in clearer speech, boosting confidence in social and professional settings. Additionally, achieving a balanced facial profile through treatment enhances self-image, supporting stronger self-esteem.
Prevention of Future Health Complications
Correcting an underbite early helps prevent advanced enamel wear, severe TMJ disorders, and other complications. This proactive approach also minimises the potential for costly future dental treatments associated with severe alignment-related damage.
Underbite Treatment Options for Different Age Groups
Children and Early Intervention
Early treatment during childhood, while the jaw is still developing, can be especially effective. Options like expanders or braces help guide jaw growth and align teeth, preventing more complex issues from developing as the child ages.
Teenagers and Adults
For developed jaws, effective treatments include braces, Invisalign, and, in severe cases, surgical options. While treatment in adults may take longer, modern orthodontic advancements make the process effective and minimally invasive, offering reliable correction options for all ages.

Frequently Asked Questions
Can an underbite be corrected without braces?
Yes, mild underbites may be corrected with alternatives like Invisalign, expanders, or retainers, while severe cases may require surgical options for effective alignment.
What age is best for treating an underbite?
Early intervention during childhood is ideal as the jaw is still developing, though effective treatment options are available for adults as well.
Are there risks associated with underbite correction?
Underbite correction is generally safe, but may involve temporary discomfort or minor gum sensitivity. Specialised care from an orthodontist helps minimise these risks.
How long does underbite correction take?
Treatment length varies by case. For children, it may take 12–24 months, while adult treatment can range from 18–36 months depending on severity.
Is early treatment necessary for all underbites?
Not always. Some mild underbites may not require early treatment, but an evaluation by an orthodontist can determine the best approach.
Can correcting an underbite improve my child’s speech?
Yes, correcting an underbite can improve speech clarity by allowing the tongue to rest and move properly, helping with pronunciation and sound formation.
Will my child need a retainer after treatment?
Most cases require a retainer post-treatment to maintain alignment and prevent teeth from shifting back over time.
What are the costs of underbite correction?
Costs vary based on treatment type and duration. Consulting with an orthodontist provides a clearer estimate based on individual needs.
