Underbite
Underbites affect more than just appearance, they impact chewing, speech, and long-term dental health. Dr Nino Gullotta and his experienced Gold Coast team provide trusted, proven treatment options. Book an early consultation to achieve lasting results for children, teens, and adults.
What is an Underbite?
An underbite is a type of malocclusion (misalignment of the jaw) where the lower teeth sit in front of the upper teeth when the mouth is closed, often leading to a prominent chin and a more pronounced jawline. This condition is contrary to a normal bite, where the upper teeth slightly overlap the lower teeth, allowing for efficient chewing and a balanced appearance.
Underbites are a common malocclusion and occur due to a variety of factors, including genetics, jaw development, and childhood habits such as thumb sucking or prolonged use of a pacifier.
In a healthy, normal bite, the upper and lower jaws slot into one another comfortably, ensuring that the pressure during biting and chewing is distributed evenly across all teeth, reducing wear and tear. However, in the case of an underbite, this alignment is disrupted, creating an imbalance that can lead to significant dental problems and discomfort. Not only do underbites cause cosmetic issues, but more severe incidences of underbite can lead to functional issues as well.
What Problems Can Underbites Cause?
Underbites cause functional, health, and aesthetic problems that affect eating, speaking, oral hygiene, and jaw health. Common issues include:
Chewing and Eating Difficulties
Misaligned teeth make chewing less efficient, often leading to imprecise biting, restricted food choices, and poor digestion.
Speech Issues
A protruding lower jaw interferes with word articulation, creating lisps, slurring, or unclear speech that affects daily communication.
Oral Hygiene Challenges
Crowded or misaligned teeth create hard-to-clean areas where plaque and bacteria accumulate, increasing the risk of decay, gum disease, and bad breath.
Facial Appearance and Confidence
An underbite changes facial balance by pushing the lower jaw forward, which can affect self-confidence in both social and professional settings.
Jaw Pain and TMJ Disorders
Misalignment places strain on the jaw joints, leading to chronic pain, clicking, or temporomandibular joint (TMJ) disorders. This causes discomfort when eating, talking, or resting.
Tooth Wear and Damage
Uneven pressure during chewing causes excessive wear, enamel loss, and tooth sensitivity, sometimes resulting in cracks or fractures.
Who Can an Underbite Affect?
An underbite can affect individuals of all types and all ages, from children to adults. Addressing the issue as early as possible prevents complications ensures the best results. Early intervention also often results in simpler and less invasive solutions.
Children and Adolescents
Early identification and intervention in younger patients can harness the latent growth potential to guide jaw development and correct underbites. This phase may involve growth modification appliances and partial braces, paving the way for normal facial development and an correctly aligned jaw.
Adults
Adults with underbites also benefit greatly from orthodontic treatment. While the approach might differ due to the cessation of growth, a combination of braces, aligners, and surgical options in extreme cases can effectively correct underbites and restore function and aesthetics.
Underbite in Infants: Early Signs and What Parents Should Know
An underbite can sometimes be seen in infants and young children as their teeth and jaws develop. While it’s normal for baby teeth to appear misaligned, a persistent underbite may indicate a jaw growth pattern that requires monitoring.
Early Signs of Underbite in Infants:
- Lower front teeth sit in front of the upper front teeth when biting
-
Jaw appears slightly protruded or the chin juts forward
-
Difficulty feeding or chewing
Should Parents Be Concerned?
Mild underbites in infants may resolve as baby teeth fall out and adult teeth emerge. If the underbite is pronounced or worsening, early assessment by an orthodontist is recommended. Early intervention can sometimes guide jaw development and prevent more complex treatment later.
When to See an Orthodontist
If you notice a strong underbite or have concerns about your child’s bite, it’s best to book an orthodontic assessment by age 7. Early evaluation allows for the best long-term outcomes.
Gullotta Orthodontics welcomes questions from parents. Our team can advise if monitoring or early treatment is needed for your child’s developing smile.
