What Is an Open Bite?
An open bite is a type of malocclusion (misaligned bite) where the upper and lower teeth do not meet when the mouth is closed, leaving a visible gap between the two arches.
This gap most commonly occurs between the front teeth (known as an anterior open bite), but it can also affect the back teeth (posterior open bite). In a healthy bite, the upper and lower teeth come together evenly, allowing for efficient chewing, clear speech, and balanced jaw function.
With an open bite, this contact is disrupted. This can affect how food is bitten and chewed, how certain sounds are formed, and how pressure is distributed across the teeth and jaw.
Open bites can develop gradually over time and may be influenced by a combination of habits, growth patterns, and tooth positioning.
What Causes an Open Bite?
An open bite can develop due to several factors. Understanding the cause helps guide the most appropriate treatment approach.
Certain habits during early development can influence how teeth and jaws form. Prolonged thumb sucking, extended use of a dummy or pacifier, and tongue thrusting can all place pressure on the front teeth, preventing them from erupting into proper alignment.
In some cases, an open bite is related to how the upper and lower jaws grow. Vertical growth patterns or skeletal differences can create a gap between the teeth, even when the teeth themselves are positioned correctly.
Improper tooth eruption, spacing, or positioning can contribute to an open bite. When teeth do not align as they come through, it can affect how the upper and lower arches meet.
Chronic mouth breathing, often linked to allergies or airway obstruction, can influence jaw development and tongue posture. Over time, this can contribute to the formation of an open bite.
What Problems Can an Open Bite Cause?
If left untreated, an open bite can lead to a range of functional and aesthetic concerns.
Difficulty Biting and Chewing
An open bite can make it difficult to bite into foods using the front teeth, often requiring compensation with the back teeth. This can affect eating habits and overall comfort.
Speech Difficulties
The gap between the teeth can interfere with the pronunciation of certain sounds, particularly “s” and “th,” leading to a lisp or unclear speech.
Excessive Wear on Back Teeth
Because the back teeth take on more pressure during chewing, they may experience increased wear over time.
Jaw Strain and Discomfort
An imbalanced bite can place additional stress on the jaw joints, potentially contributing to discomfort or tension.
Oral Hygiene Challenges
Misalignment can make certain areas harder to clean, increasing the risk of plaque build-up and gum issues.
Aesthetic Concerns and Confidence
The visible gap between the teeth can affect smile appearance, which may impact confidence in social or professional settings.
Who Can Be Affected by an Open Bite?
An open bite can affect both children and adults. Early identification often allows for simpler and more effective treatment.
Children and Adolescents
In younger patients, open bites are often linked to habits or growth patterns. Early assessment allows orthodontists to guide development and reduce the likelihood of more complex treatment later.
You can learn more about early orthodontic care on our early intervention page.
Adults
Adults can also develop or retain an open bite. While jaw growth is complete, orthodontic treatment can still effectively correct alignment and improve function. Treatment may involve braces, aligners, or a combination of approaches depending on the case.
Correcting an Open Bite
Correcting an open bite requires a personalised and carefully planned approach. At Gullotta Orthodontics, treatment is designed around each patient’s individual needs, taking into account the cause, severity, and overall bite relationship.

Open Bite Treatment Options
Braces
Lightforce braces are 3D-printed and custom-designed for each patient, providing a highly precise and efficient treatment for open bites. This innovative approach ensures a more comfortable fit and can sometimes reduce treatment time.
2. Clear Braces
For patients who prefer a more discreet treatment option, clear braces offer the same effectiveness as traditional braces but with transparent brackets that blend in with natural teeth.
3. Metal Braces
Damon metal braces use self-ligating technology to reduce friction and optimise tooth movement. They can be particularly effective in treating open bites by allowing for smoother and more efficient tooth repositioning.
Clear aligners offer a removable and nearly invisible alternative to braces. They can be an effective solution for mild open bites by gradually shifting the teeth into better alignment.
- Invisalign: A leading brand in clear aligners, Invisalign is custom-made for each patient and provides a comfortable and discreet way to correct open bites.
- Spark Aligners: Spark aligners are designed with enhanced clarity and precision, offering a nearly invisible treatment experience for open bite correction.
Whether using braces or aligners, our goal is to help you achieve a well-balanced, functional, and confident smile. If you’re concerned about your bite alignment, book a consultation with Dr. Gullotta and our team to explore your options.
Can an open bite fix itself?
In some mild cases, especially in young children, an open bite related to habits may improve if the habit stops early. In most cases, orthodontic treatment is required to fully correct the issue.
What causes an open bite in adults?
In adults, an open bite may result from long-term habits, jaw structure, or untreated alignment issues from earlier in life.
Can an open bite affect speech?
Yes, an open bite can affect the pronunciation of certain sounds, particularly “s” and “th,” leading to speech difficulties.
How long does it take to fix an open bite?
Treatment time varies depending on the severity of the open bite and the treatment method used. A consultation provides a clear and personalised timeframe.
