Identifying Common Orthodontic Problems
Common orthodontic problems affect a large proportion of the population, and very few people develop perfectly aligned teeth without some form of intervention. Understanding what these issues are is the first step toward addressing them.
Key Takeaways
- The Australian Society of Orthodontists recommends children attend an initial clinical assessment by age 7 to identify potential developmental issues.
- Crowding is the most frequent reason patients seek braces in Brisbane, often occurring when there is insufficient space for permanent teeth to emerge.
- Modern clear aligner options, including Spark and Invisalign, may be suitable for adults with healthy teeth and gums seeking to address long-standing misalignments.
- Maintaining results requires a dedicated retention phase, typically involving a combination of fixed and removable retainers to support long-term stability.
- Early intervention during childhood may help simplify future treatment needs by guiding jaw development while the facial bones are still growing.
Here is a quick overview of the most frequently seen orthodontic problems:
| Orthodontic Problem | Brief Description |
|---|---|
| Crowding | Insufficient space for permanent teeth to erupt straight |
| Spacing | Gaps between teeth due to missing teeth or jaw size |
| Overbite | Upper front teeth overlap too far over the lower teeth vertically |
| Overjet | Upper front teeth protrude too far forward horizontally |
| Underbite | Lower teeth sit in front of the upper teeth |
| Crossbite | Upper teeth sit inside the lower teeth on one or both sides |
| Open bite | Upper and lower front teeth do not meet when the mouth is closed |
| Dental midline discrepancy | The centrelines of the upper and lower teeth do not align |
| Impacted teeth | A permanent tooth fails to erupt properly through the gum |
These issues can range from mild cosmetic concerns to problems that may affect chewing, speech, and overall bite function. Many of these issues are worth monitoring over time, as some may become more complex if left unaddressed.
I am Dr Nick, a Specialist Orthodontist based in Brisbane with over 30 years of experience and more than 11,500 patients treated across our Chermside and Spring Hill locations. Throughout my career, addressing common orthodontic problems at every stage of life has been the foundation of my clinical practice. In the sections below, I will walk you through each major issue, how it is diagnosed, and what treatment options are available.
Recognising the signs of a malocclusion, or “bad bite,” allows families to seek advice before dental issues escalate. Most people associate orthodontics with straight teeth, but we focus equally on how the upper and lower jaws function together. A healthy bite ensures that chewing forces are distributed evenly across all teeth, which may reduce the likelihood of premature enamel wear.
We categorise these issues into dental problems, involving the position of the teeth, and skeletal problems, involving the alignment of the jaw bones. Many patients present with a combination of both.
Clinical Diagnosis of Common Orthodontic Problems
We begin every case with a comprehensive clinical assessment to understand the unique anatomy of the patient. This process involves more than just looking at the teeth. We utilise digital modelling for clinical planning to create a three-dimensional representation of the mouth.
Our diagnostic toolkit includes specialised X-rays, such as lateral cephalometric and panoramic views, which show us the relationship between the teeth, roots, and jaw joints. Physical examinations allow us to observe how the jaw moves during speech and chewing. If you have specific questions about our diagnostic process, you can find more information on our FAQ.
Why Early Detection Matters
The Australian Society of Orthodontists recommends that children have their first orthodontic screening by age 7. At this stage, the first permanent molars have usually emerged, establishing the back bite. We can identify subtle issues with jaw growth and emerging permanent teeth while the facial bones are still developing.
Early monitoring does not always mean immediate treatment. In many cases, we simply observe the child’s development every 6 to 12 months. This proactive approach allows us to intercept certain problems, such as crossbites or severe protrusion, at the most effective time. You can learn more about the benefits of early screening in our article, Don’t Wait Until They Are Teenagers to See an Orthodontist.
Crowding and Spacing Variations
The relationship between the size of the teeth and the size of the jaw determines whether teeth will be crowded or have excessive gaps. These are two of the most common reasons patients visit our Brisbane clinics. Both conditions can influence oral hygiene and the long-term health of the gums.
Managing Dental Crowding
Dental crowding occurs when there is insufficient room in the jaw for all permanent teeth to erupt in their correct positions. This often results in teeth that are rotated, overlapped, or displaced toward the lip or tongue. Crowding is a significant clinical concern because overlapping surfaces are notoriously difficult to clean with a toothbrush and floss.
Difficulty with hygiene may increase the risk of dental decay and periodontal disease over time. We often manage crowding by creating space through various methods, such as palatal expansion in growing children or the strategic movement of teeth. For more details on how we address these issues, see our post on Understanding Braces Types and How They Fix Crooked Teeth.
Addressing Excessive Spacing
Excessive spacing is the opposite of crowding and presents as noticeable gaps between the teeth. This may be caused by small teeth, a large jaw, or missing teeth. A common form of spacing is a midline diastema, which is a gap between the two upper front teeth.
While some spacing is purely a matter of personal preference, large gaps can lead to food entrapment and gum irritation. We use various appliances to guide teeth together and close these spaces. Modern systems have made this process very discreet for our adult patients. Learn more about custom options in The Magic of Custom Aligners: Your Personalized Path to a Straighter Smile.
Understanding Bite Misalignments
A functional bite is one where the upper teeth sit slightly outside the lower teeth, and the molars fit together like gears. When this relationship is disrupted, we call it a malocclusion. Different types of misalignments require specific clinical approaches.
Vertical and Horizontal Discrepancies
We often see discrepancies in how teeth overlap both vertically and horizontally. A deep bite (or overbite) occurs when the upper front teeth overlap the lower front teeth excessively in a vertical direction. In severe cases, the lower teeth may even touch the roof of the mouth, which can cause discomfort.
Overjet refers to the horizontal distance between the upper and lower front teeth, often described as protrusion. This is different from an overbite, though they can occur together. Protrusion may increase the risk of accidental injury to the front teeth. We treat many adults for these issues to help preserve their enamel. Read more in our Deep Dive into Adult Orthodontics.
Functional Impacts of Malocclusion
Malocclusions can have several functional consequences beyond the position of the teeth. An underbite, where the lower teeth sit in front of the upper teeth, can make chewing certain foods difficult and may contribute to uneven jaw growth. Crossbites, where the upper teeth sit inside the lower teeth, can cause the jaw to shift to one side, potentially leading to facial asymmetry if left unaddressed during growth.
Open bites occur when the front teeth do not meet even when the back teeth are together. This is often linked to childhood habits like thumb sucking or tongue thrusting and can impact speech clarity. Addressing these functional concerns is a primary goal of specialist care. Explore the technical side of these corrections in Beyond Braces: The Role of a Dental Alignment Specialist.
Clinical Approaches to Common Orthodontic Problems
We offer several treatment modalities at our Chermside and Spring Hill practices. Each option is selected based on the specific clinical needs of the patient and their lifestyle preferences.
| Treatment Option | Primary Use | Visibility |
|---|---|---|
| Metal Braces | Complex misalignments and bite corrections | High |
| Clear Ceramic Braces | Discreet correction for all ages | Low |
| Spark Aligners | Mild to moderate crowding and spacing | Very Low |
| Invisalign | Versatile clear aligner system | Very Low |
We recommend a consultation to determine which of these may be suitable for your specific situation. You can find more information about our Invisalign services online.
Specialized Appliances and Techniques
In addition to braces and aligners, we utilise specialised appliances to guide development. Palatal expanders can help widen a narrow upper jaw in growing children, which may reduce the need for tooth extractions later. Space maintainers are used when a baby tooth is lost prematurely to ensure the permanent tooth has enough room to emerge.
These early intervention techniques are most effective when utilised during the “mixed dentition” stage, where a child has a combination of baby and permanent teeth. This typically occurs between the ages of 7 and 10. For a complete overview of these options, visit our Guide to Kids Orthodontic Options.
The Role of Clear Aligner Technology
Clear aligner systems like Spark and Invisalign have changed how we manage common orthodontic problems. These systems use digital modelling for clinical planning to design a series of removable plastic trays. Each tray applies calibrated pressure to move teeth into the desired position.
Aligners are popular because they are removable for eating and cleaning. However, they require a high level of patient cooperation, as they must be worn for approximately 22 hours per day to be effective. We assess each patient’s clinical suitability for aligners during their initial consultation. Learn more in The Complete Guide to Invisible Braces.
The Importance of Retention and Long-Term Stability
The retention phase is just as important as the active phase of treatment. Once braces or aligners are removed, the teeth have a natural tendency to shift back toward their original positions. This is because the bone and supporting fibres around the roots need time to stabilise in their new locations.
We use a combination of retention methods to ensure long-term stability. This typically includes a fixed wire retainer bonded behind the lower front teeth and clear removable plastic retainers made in-house for nightly wear. You can find details about what is included in our care on our pricing page.
Preserving Clinical Results
Tooth mobility is a natural part of human biology, and teeth can continue to move slightly throughout life due to biting forces. Consistent use of retainers is the only way to preserve the results achieved during treatment. We monitor our patients during the retention phase to ensure their appliances are fitting correctly.
If a retainer is lost or broken, it is important to have it replaced quickly to prevent unwanted movement. We regularly share tips on maintaining your oral health and retainers on our blog.

Frequently Asked Questions
What are the most common orthodontic problems?
The most frequent issues include dental crowding, excessive spacing, and various types of bite misalignments such as overbites or underbites. Crowding often occurs when the jaw is too small to accommodate all permanent teeth, leading to overlapping or rotated teeth. Bite issues involve how the upper and lower teeth meet, which can impact chewing and long-term tooth wear.
When should my child see an orthodontist?
Specialists generally recommend an initial assessment by age 7 to monitor the transition from baby teeth to permanent teeth. This timing allows the orthodontist to identify subtle issues with jaw growth and emerging teeth while the facial bones are still developing. Early detection may help simplify future treatment or even reduce the need for more invasive procedures later in life.
Can adults treat common orthodontic problems?
Orthodontic treatment is highly effective for adults provided the teeth and supporting gum tissues are healthy. Many adults choose modern options like Spark clear aligners or ceramic braces for a more discreet appearance during their professional lives. Addressing misalignments in adulthood can help improve oral hygiene and reduce the risk of uneven enamel wear.
How are these issues diagnosed?
Diagnosis involves a comprehensive clinical examination supplemented by digital modelling and specialised X-rays. These tools allow the orthodontist to see the relationship between the teeth, roots, and jaw structure. A personalised treatment plan is then developed based on these specific anatomical findings to ensure the most appropriate approach is taken.
What causes orthodontic misalignments?
Most orthodontic issues are hereditary, meaning they are passed down through genetics, such as jaw size or tooth shape. However, environmental factors and certain childhood habits like prolonged thumb sucking or early loss of baby teeth can also influence dental development. Injuries to the face or jaw can sometimes lead to alignment changes that require professional intervention.
Are there alternatives to braces?
Clear aligner systems like Invisalign and Spark offer a popular alternative to traditional fixed braces for many common misalignments. These systems use a series of custom-made, removable plastic trays to gradually guide teeth into their desired positions. The suitability of aligners depends on the complexity of the case and the specific clinical goals identified during the consultation.
How long does treatment usually take?
The duration of treatment varies significantly depending on the severity of the misalignment and the biological response of the individual. Most comprehensive treatments last between 12 and 24 months, though minor adjustments may be completed in a shorter timeframe. Consistent cooperation, such as wearing elastics or aligners as directed, is essential for maintaining the estimated timeline.
Why are retainers necessary?
Retainers are essential because teeth have a natural tendency to shift back toward their original positions after braces or aligners are removed. The bone and supporting tissues need time to stabilise around the new tooth positions. Using a combination of fixed wires and removable clear retainers ensures that the clinical results are preserved for the long term.
