Jaw Surgery

Re-shape Your Jaw to Eat, Sleep, Speak & Smile Better

What is Jaw Surgery?

Jaw surgery, also known as orthognathic surgery, is a dental procedure performed to realign the jaws and teeth to improve their function and appearance. Jaw surgery may be necessary to correct underbites, overbites, crossbites, and other jaw-related problems that cannot be corrected with orthodontic treatment alone. It may involve moving the upper jaw (maxilla), lower jaw (mandible), or both. In some cases, bone grafts may be used to augment the jawbone.

Jaw surgery is often performed in conjunction with orthodontic treatment to achieve the best results. The combination of surgery and orthodontics can improve both the function and appearance of the teeth and jaws, leading to a healthier bite and a more balanced facial appearance.

When is Jaw Surgery Recommended?

Jaw surgery may be recommended to people who:

  • are suffering from Temporomandibular Joint Disorder (TMJ) and not responding to conservative treatments such as medication and physiotherapy
  • are having difficulty eating due to jaw-related issues
  • have severe sleep apnoea caused by jaw-related issues
  • have an “open bite” or a gap between your top and bottom teeth
  • have experienced a facial injury that has caused one’s jaws to become misaligned

How is Jaw Surgery Performed?

  1. The patient will first have a consultation with a dental specialist to discuss the procedure, risks, and outcomes. A review of the patient's medical history, imaging tests, and a dental exam will also be performed.
  2. The patient will usually be placed under general anaesthesia. The surgeon accesses the jaw bones through incisions made inside the mouth, cuts and repositions the bones, and secures them with metal plates, screws, or wires. The incision will then be closed with sutures.
  3. Post-operative care usually involves an observation period at the premise for monitoring before being discharged. While some procedures are just day surgeries, others may require hospitalisation.
  4. Recovery from jaw surgery takes several weeks to months. Patients are usually given pain medications and some may be recommended physiotherapy to improve their jaw function and mobility. In some case, orthodontic treatment also be incorporated for optimal results.

Risks and Possible Complications

Though rare in the hands of an experienced oral maxillofacial surgeon, some risks to take note of include:

  • Infection or excessive bleeding at the surgical site
  • Complications associated with anaesthesia, such as allergic reactions
  • Temporary/permanent damage to the nerves that control sensation and movement in the face and mouth
  • Changes in bite or jaw function in the unlikely event that the surgery does not achieve the desired outcome

Recovery and Aftercare

Patients may experience swelling, bruising, and discomfort initially, which are usually manageable with proper adherence to post-operative care. During recovery, a soft or liquid diet is recommended. Good oral hygiene is also very important to keep the area clean. Scheduled follow-up appointments are necessary to monitor healing and address any issues that may arise. Full recovery may take several months.

FAQs on Jaw Surgery

  • Are there alternatives to jaw surgery?

    Depending on the type and severity of the condition, alternatives may include orthodontic treatment, dental restorations, functional appliances, or therapy. Consulting with a dental specialist can help determine the best approach for your situation.

  • Will I need to stay in the hospital after my jaw surgery?

    Patients often require a brief hospital stay after jaw surgery for monitoring and pain management. However, some may not. The length of stay will vary depending on the complexity of the surgery and individual’s health.

  • Is jaw surgery painful?

    No, jaw surgery is performed under anaesthesia, so no pain will be felt. However, there will be post-operative pain and swelling, which can be managed with pain medications and the appropriate use of ice packs.

  • Can children undergo jaw surgery?

    In severe cases, jaw surgery may be considered for children and adolescents. An evaluation by an oral maxillofacial surgeon or orthodontist will let you know if this is the best course of action for the patient.
