Overbite Treatment Options in Sydney: Braces, Invisalign, and When Surgery Is Needed

Overbite treatment options in Sydney are broader than many patients realise. The word “overbite” often prompts immediate assumptions about surgery or long, complex treatment — but for the majority of patients, effective overbite correction is achievable with orthodontics alone. The key is a thorough diagnosis to understand whether your overbite is dental (teeth position) or skeletal (jaw structure) in origin.

At Orthoworx, Dr Eugene Chan has spent decades treating overbite cases of all severities, from mild overlaps in teenagers to complex adult presentations. This guide covers all overbite treatment options available in Sydney and what the right choice looks like for different patients.

What Causes an Overbite?

Understanding overbite treatment options starts with understanding the cause. Overbites develop from a combination of:

• Genetic jaw size discrepancies between upper and lower jaws
• Over-eruption of the upper front teeth or under-eruption of the back teeth
• Early childhood habits (prolonged dummy use, thumb-sucking)
• Teeth grinding, which can deepen the bite over time
• Missing lower back teeth, which remove support for the bite

Types of Overbite: Dental vs Skeletal

The most important classification for determining overbite treatment options is whether the overbite is dental or skeletal. A dental overbite results primarily from the position of the teeth relative to each other — the jaws themselves are normally sized and positioned. A skeletal overbite involves an underlying jaw bone discrepancy: typically an overdeveloped upper jaw or underdeveloped lower jaw. This distinction drives everything about treatment selection.

Overbite Treatment Options for Children

When treating overbite in growing children, the most powerful tool is the jaw itself. The jaw is still developing, meaning orthodontists can use that growth to their advantage. Overbite treatment options for children include:

• Functional appliances: Removable appliances like Herbst appliances or Twin Block appliances redirect jaw growth to bring the lower jaw forward, reducing the skeletal component of the overbite
• Braces with auxiliaries: Traditional braces combined with bite turbos, elastics, or other bite-correcting auxiliaries address both the dental and mild skeletal components
• Palatal expanders: Used where a narrow upper arch contributes to the overbite by widening the palate during growth

According to the Australian Society of Orthodontists, children with significant overbites benefit most from assessment before the growth spurt to maximise correction opportunities during the pubertal growth window.

Overbite Treatment Options for Adults

In adults, jaw growth is complete, which changes the overbite treatment options available. The skeletal component can no longer be redirected through growth modification alone. Options include:

• Traditional braces: Highly effective for dental overbites. Bite turbos (small acrylic ramps bonded to upper teeth) temporarily prevent the back teeth from biting together, allowing the front teeth to intrude and the bite to open
• Invisalign with bite ramps: Dr Chan regularly achieves effective overbite correction using Invisalign’s integrated bite ramp features and precision attachments for adult dental overbite cases
• Orthognathic surgery combined with braces/Invisalign: For severe skeletal overbites in adults where orthodontic correction alone cannot achieve a functional, stable result

Can You Fix an Overbite Without Surgery?

For most patients exploring overbite treatment options, the answer is yes. Dental overbites and mild-to-moderate skeletal overbites can typically be corrected effectively with braces or Invisalign alone. The key determinant is the severity of the skeletal discrepancy. If the jaw misalignment exceeds what teeth movement can compensate for, surgery may be the only route to a stable, functional result.

Dr Chan will assess this during your initial consultation using clinical records and, where needed, cephalometric X-rays and digital treatment planning.

When Is Jaw Surgery Needed?

Orthognathic (jaw) surgery becomes one of the overbite treatment options when the skeletal discrepancy is too large for orthodontic compensation to produce a functional, stable result. Indicators include:

• A significant Class II skeletal pattern confirmed on cephalometric X-ray
• Adult patient past the growth period with a severe jaw discrepancy
• Functional issues (chewing, breathing, speech) that orthodontics alone cannot resolve
• Facial profile concerns the patient wishes to address

Surgery is always performed in conjunction with orthodontic treatment — braces or Invisalign are used before and after surgery to fine-tune tooth position. The combined result of surgical correction and orthodontic finishing often produces dramatic improvements in both function and aesthetics.

Overbite Treatment Costs in Australia

Costs for overbite treatment options in Australia vary by complexity:

• Braces (dental overbite): $6,000–$9,000
• Invisalign (dental overbite): $6,000–$10,000
• Functional appliance + braces (child): $5,500–$8,500
• Orthognathic surgery + orthodontics: $20,000–$35,000+ (surgery typically partially covered by Medicare and private health)

Orthoworx offers interest-free payment plans to make all overbite treatment options accessible.

Frequently Asked Questions

What are the best overbite treatment options?

The best option depends on whether your overbite is dental or skeletal, your age, and severity. Braces and Invisalign are effective for most dental overbites. Functional appliances work well in growing children. Surgery is reserved for severe skeletal cases.

Can Invisalign fix an overbite?

Yes, for dental overbites and mild skeletal overbites. Invisalign uses bite ramps and precision attachments to achieve overbite correction without traditional braces. Severe skeletal overbites may need surgery.

How long does overbite treatment take?

Overbite treatment typically takes 18–30 months with braces or Invisalign for dental cases. Children using functional appliances may complete the growth modification phase in 12 months, followed by braces.

Can an overbite be fixed without braces?

Invisalign is an alternative to braces for overbite correction in suitable cases. Surgery without braces is not appropriate — orthodontics before and after surgery is always required.

Is overbite treatment covered by Medicare or private health in Australia?

Orthodontic treatment for overbite is covered under private health extras policies. If jaw surgery is required, Medicare and private health hospital cover may contribute to surgical costs. Consult your fund for benefit levels.

Does an overbite get worse with age?

For most people, a dental overbite deepens gradually with age, particularly with grinding. Treating it earlier is generally simpler and less expensive than waiting.

What is the difference between an overbite and a deep bite?

A deep bite specifically refers to excessive vertical overlap of the upper front teeth over the lower teeth. An overbite is a broader term including both horizontal and vertical components. All deep bites are a form of overbite, but not vice versa.

Can an untreated overbite cause jaw pain?

Yes. An untreated significant overbite can cause TMJ (jaw joint) problems, pain, clicking, and headaches over time. This is one of the functional reasons to treat it, beyond aesthetics.

At what age is overbite treatment most effective?

In children, overbite treatment is most effective during the pubertal growth spurt (roughly age 10–14), when jaw growth can be redirected. Adult treatment is still highly effective for dental components but cannot use growth to advantage.

What happens if you don’t treat an overbite?

Untreated overbites can lead to premature tooth wear, gum damage, jaw pain, TMD, and progressive worsening of the bite. In severe cases, the lower teeth may traumatically contact the upper palate with every bite.
