Straightening Out Overcrowding and Underbites
Overbite correction with braces can help improve how the upper and lower teeth meet when treatment is suitable for the bite pattern. At NK Orthodontist in Chermside, Dr Nick can assess whether braces, ceramic braces, or clear aligners may be appropriate for your needs.
Key Takeaways
- Overbite correction with braces may be suitable for many dental and mixed bite variations, with treatment often planned over 12 to 24 months.
- An initial orthodontic assessment by age 7 can help identify bite development patterns and support future planning.
- Wearing elastics for close to 24 hours a day, if prescribed, can help keep bite correction on schedule.
I’m Dr Nick, a Specialist Orthodontist with over 30 years of experience. I have treated more than 11,500 patients and I see patients at our Brisbane practice in Chermside.
Overbite correction with braces is a common orthodontic treatment for children, teenagers, and adults in Brisbane. If your upper front teeth overlap your lower teeth more than expected, a Specialist Orthodontist can assess whether braces may be suitable.
A healthy bite usually shows around 2 to 4 millimetres of overlap between the upper and lower front teeth. Some people have a deeper overbite than this, so an orthodontic assessment is the best way to understand whether treatment may be useful.
Some overbites relate mainly to tooth position, and others relate to jaw structure. A clinical assessment helps identify the type and supports a treatment plan that fits your needs.

Understanding Dental and Skeletal Overbites
We categorise overbites into two primary types based on their origin. A dental overbite occurs when the teeth are misaligned or crowded, often placing the upper teeth further forward or the lower teeth further back. In these cases, the jawbones are often proportionate, and tooth position creates the excessive overlap.
A skeletal overbite relates to the growth and development of the jawbones. This may mean the upper jaw is larger, the lower jaw is smaller, or both are contributing to the bite relationship. Because these variations involve bone structure, they often need a different clinical approach from a purely dental overbite.
Specialist orthodontists use digital X-rays and cephalometric analysis to determine whether an overbite is dental, skeletal, or mixed. This distinction guides appliance selection and treatment planning. You can find more details on our Services page, and the Australian Society of Orthodontists also provides general information about orthodontic care in Australia.
Distinguishing Overbite from Overjet
It is common for patients to confuse overbite with overjet, but they describe different dimensions of the bite. An overbite refers to the vertical overlap of the teeth. If your upper teeth cover more than a third of your lower teeth, you are seeing vertical overlap.
An overjet refers to the horizontal distance between the upper and lower front teeth. Many patients seeking overbite correction with braces have a combination of vertical overlap and horizontal overjet, so both measurements matter during clinical planning.
Causes of Bite Variations
Genetics often play the biggest role in how the bite develops. Family traits influence jaw size, tooth size, and the amount of room available for teeth to erupt.
External factors and habits can also influence development. Prolonged thumb sucking or dummy use past the age of 5 can place pressure on developing teeth and bone. Tongue thrusting and chronic nail-biting may also contribute to changes in alignment over time.
How Braces Address Vertical and Horizontal Alignment
Braces work by applying constant, controlled pressure to the teeth, which encourages the surrounding bone to remodel. This allows the teeth to move into a more functional and balanced position. When we use braces for overbite correction, we are looking at the relationship between the top and bottom arches as a single unit.
The process typically begins with aligning the individual teeth within each arch. Once the teeth are straight, we move into the bite-correction phase. This is where we focus on how the upper and lower teeth meet when you close your mouth.
The Role of Elastics in Overbite Correction
Elastics, or rubber bands, are often the engine that drives bite correction. These small bands hook onto specific brackets on the upper and lower teeth. They provide the connective tension needed to move the arches relative to one another.
We typically use Class II elastics for overbite cases, stretching from the upper front area to the lower back area. This encourages the upper teeth to move back and the lower teeth to move forward. Compliance is the most important factor here. Because we ask you to wear these bands almost 24 hours a day, your commitment directly impacts how quickly we can achieve the desired alignment.
Managing Vertical Overlap with Braces
In cases of a “deep bite,” where the upper teeth almost entirely hide the lower teeth, we need to manage the vertical space. We may use bite turbos or bite blocks, which are small mounds of resin placed on the back of the teeth. These prevent you from biting all the way down, allowing the back teeth to erupt further or the front teeth to be moved vertically.
By flattening the “curve of Spee” (the natural curve of the lower teeth), we can open the bite. This creates a healthier relationship between the arches and reduces the risk of the lower teeth biting into the roof of the mouth. This vertical management is a core part of the comprehensive plans we develop at NK Orthodontist.

Traditional Metal and Ceramic Options
Metal braces remain a popular choice because they are highly reliable and precise. We use high-quality brackets that allow for fine-tuned movements, which is particularly helpful for severe skeletal overbites. At our Chermside practice, we ensure these are fitted with close attention to detail throughout treatment.
Ceramic braces offer the same clinical capabilities as metal but with a more discreet appearance. The brackets are made of a translucent material that blends with the natural colour of your teeth. Many adult patients and older teens choose ceramic brackets for their upper teeth to maintain a professional look while undergoing treatment.
Clear Aligner Suitability
Clear aligners, such as Invisalign or Spark aligners, have become a common alternative to braces for overbite correction. These systems use a series of custom-made plastic trays to move the teeth. For growing teenagers, certain aligner features can help guide the lower jaw forward as they grow.
As a Platinum Elite Invisalign provider, Dr Nick has extensive experience using these systems to manage bite variations. While aligners are suitable for many dental overbites, we will always advise you if traditional braces are a more appropriate tool for your specific skeletal structure. You can learn more about these options during a book a consultation session.
Expected Timelines and Factors for Success
One of the first questions we hear is, “How long will this take?” The answer depends on the complexity of the bite and how the individual’s body responds to treatment. On average, a moderate overbite may be suitable for a treatment period of 18 to 24 months.
Mild cases involving only minor tooth movements might be completed in 12 to 18 months. Conversely, severe skeletal overbites, especially in adults where the jaw is no longer growing, can take 30 months or longer. We monitor your progress every 6 to 8 weeks at our Chermside practice to ensure everything is moving according to the plan.
Factors Influencing Duration
The severity of the initial overlap is the most significant factor. If we need to move the jaw several millimetres or address significant crowding at the same time, the timeline will naturally be longer. Biological factors also play a role; some people’s teeth simply move more readily than others.
Patient cooperation is the factor you can control. This includes attending all scheduled appointments, maintaining excellent oral hygiene, and, most importantly, wearing your elastics exactly as prescribed. Missing even a few days of elastic wear can allow the teeth to drift back, potentially adding weeks or months to the total time.
The Importance of the Retention Phase
The day the braces come off is a major milestone, but it is not the end of the process. Teeth have a natural memory and will try to shift back toward their original positions. To prevent this, we use two types of retainers.
We typically bond a fixed retainer, which is a very thin wire, behind the lower front teeth where it cannot be seen. We also provide removable clear plastic retainers, made in-house, to be worn at night. Wearing your retainers indefinitely as instructed is the only way to help the alignment achieved through overbite correction with braces remain stable for the long term.

Frequently Asked Questions
Can braces address an overbite in adults?
Braces may effectively address overbites in adults of any age. While the jawbones are no longer growing, the teeth can still be moved through the bone with consistent pressure. Many adults find that modern options like ceramic braces or clear aligners allow them to manage their bite discreetly. In some very complex skeletal cases, we may discuss a combination of orthodontic care and other clinical approaches to achieve the best possible relationship between the arches.
How long does it take to address an overbite with braces?
The timeframe for treatment typically ranges from 12 to 30 months depending on the complexity of the case. A mild dental overbite might be managed in a shorter period, whereas a significant skeletal discrepancy usually requires more time to stabilise. During your initial consultation, Dr Nick will provide a more specific estimate based on your clinical needs and digital modelling.
Are rubber bands always necessary for overbite correction?
Rubber bands, or elastics, are a common component of treatment because they provide the connective force needed to move the jaw. They are usually introduced once the teeth are straight to help the upper and lower arches fit together correctly. Consistent wear is essential, as the pressure must be constant to be effective; failing to wear them as directed is one of the most common reasons for extended treatment times.
Can clear aligners address an overbite?
Clear aligners are often suitable for addressing mild to moderate overbites in both teens and adults. These systems use specific attachments on the teeth and elastics to achieve the necessary vertical and horizontal movements. For very complex skeletal issues, Dr Nick might recommend traditional braces, as they offer a higher degree of precision for significant jaw repositioning.
Does the process of addressing an overbite cause discomfort?
Patients often experience some temporary sensitivity for a few days after braces are first fitted or following an adjustment appointment. This occurs as the ligaments surrounding the teeth respond to the new pressure. Most people find that the mouth adapts quickly, and any minor tenderness can usually be managed with standard over-the-counter relief.
What happens if an overbite is left unaddressed?
Leaving a significant overbite unaddressed may lead to uneven wear on the tooth enamel over time. It can also contribute to increased tension in the jaw joints (TMJ) and may make the front teeth more susceptible to damage from accidental impacts. Addressing the bite helps to distribute chewing forces more evenly, which supports long-term oral health and function.
Is jaw surgery required for all severe overbites?
Jaw surgery is generally only considered for severe skeletal overbites in adults where the difference in jaw size is too large for braces alone to manage. In growing children and teenagers, we can often use growth-guided techniques to encourage the jaws into a better relationship without the need for invasive procedures. A thorough clinical assessment is always the first step to determining if a case can be managed with braces alone.
Why are retainers so important after the braces are removed?
Retainers are vital because teeth have a natural tendency to shift back toward their original positions once the braces are removed. The bone and gums need a significant amount of time to settle and harden around the new positions of the teeth. By wearing your retainers as prescribed, usually every night, you can help ensure that the alignment achieved during your treatment remains stable for many years.
