Jaw surgery and braces  

Jaw surgery, also called orthognathic surgery, can help correct and address severe orthodontic issues and discrepancies between the upper and lower jaws. This might include misaligned bites, significant facial asymmetry and potentially improving airway dimensions. That’s why we are answering some of the common questions about jaw surgery as it relates to orthodontic treatment, so you can be more informed about what’s involved.

What is jaw surgery?

Jaw or orthognathic surgery is a specific type of surgery that corrects and realigns the jaw bones, teeth and bite. It can also improve the overall look of a person’s face, making it appear more symmetrical or improve the facial profile. 

Not everyone who has teeth or jaw issues will need corrective jaw surgery. These procedures are usually for people who have structural or cosmetic problems that can’t be fixed with orthodontic treatment alone. If you think you may need jaw surgery, speak to a trusted specialist orthodontist first who will be able to give you a referral to a surgeon. 

What happens during jaw surgery?

Jaw surgery is performed at a hospital under general anaesthetic. Usually, jaw surgery can be completed inside the mouth – meaning there will be no visible scarring on the face. During orthognathic surgery, small and precise cuts are made in the jawbone, which allows your surgeon to move them into a better position. The bones are then held in position by small, titanium bone fixation plates and screws.

Do I need braces before an orthognathic surgery? 

Most people will have braces before and after jaw surgery. This ensures your teeth and jaw are prepared and in the best position possible prior to surgery. Braces also help ensure healing occurs safely and proper jaw and tooth alignment is achieved post-surgery.

How long after jaw surgery do braces come off? 

Your specialist orthodontist and surgeon will decide on a treatment plan and timing that suits your needs best – including how long you will need to wear braces after jaw surgery. Generally, this is about six to nine months after surgery. The overall orthodontic process, from start to finish, usually takes approximately two years in total.

What is the best age for jaw surgery? 

While there is no set age, jaw surgery is generally best performed when a person’s bone is more mature or is past the teenage growth spurt. However, depending upon the individual case requirements, jaw surgery can be performed at an earlier or later stage of life too.

What is the average age for jaw surgery?

The average age for jaw surgery tends to be around 18, as the ‘ideal age’ for this type of treatment is when the jaw has matured and fully developed. But that doesn’t mean you can’t have jaw surgery later in life – your orthodontist will help you to understand when and why surgery might be necessary, and what other options may be available.

Is jaw surgery high risk? 

No. Jaw surgery, when performed by a specialist oral or maxillofacial surgeon, is a safe and common procedure. 

Is jaw surgery painful?

As you’ll be under general anaesthetic, you won’t feel any pain during the surgery. However, you might feel some pain or discomfort after the surgery, but it will usually go down by the time you’re discharged from the hospital or your surgeon may prescribe painkillers to help in the days following.

When you’re home, your face will most likely swell and your jaw might feel stiff and uncomfortable. You can apply an ice pack to your face to help reduce swelling, and keep your head elevated as much as possible afterwards to support the recovery period.

Will jaw surgery change my face? 

Yes, jaw surgery can change the look and appearance of your face. This is because the jaw bones are usually cut and moved or placed in a new position, changing the foundation bones which are the scaffold for your facial profile and symmetry. How noticeable this change is depends on how significant the pre-treatment concern or problem was.

How much does jaw surgery cost in Australia?

The cost of jaw surgery in Australia can range from $6,000 to $12,000. But at the end of the day, the price will vary from clinic to clinic You’ll also have to cover the cost of the anaesthetist and any additional hospital fees, which may be covered by Medicare or your private health insurance if your policy covers it.

Is jaw surgery covered by Medicare?

If your surgery is for the purposes of correcting your jaw alignment or supporting the treatment of other orthodontic issues, then Medicare should cover some of the costs. However, if your jaw surgery is for cosmetic purposes then it won’t be covered by Medicare.

How long is recovery from jaw surgery?

The recovery time from jaw surgery will vary between individuals. But as a general rule, healing can take anywhere between six and 12 weeks. This may be followed by orthodontic treatment which can last up to 2 years. Talk to your practitioners for more information about your specific timeline.
