Considering orthognathic surgery? We understand you have questions. This procedure corrects jaw irregularities, improves facial appearance and resolves functional issues like chewing difficulties or speech problems. At London Dental Specialists, our experienced surgeons guide patients through every stage—from initial consultation to complete recovery. Recovery typically takes six weeks for initial healing, with full recovery within 12 weeks. While temporary discomfort, swelling and speaking difficulties are normal post-surgery, our team provides comprehensive aftercare to ensure optimal results. Below are answers to the most common questions our patients ask about this transformative procedure.
What is orthognathic surgery?
Orthognathic surgery, also known as corrective jaw surgery, is a procedure that corrects skeletal irregularities of the jaw and face. It is performed to improve functional problems such as difficulty chewing, speaking, or breathing, as well as to enhance facial aesthetics. At London Dental Specialists, this surgery is typically performed in conjunction with orthodontic treatment to ensure optimal alignment of the teeth and jaws.
Who is a good candidate for orthognathic surgery?
Good candidates for orthognathic surgery at London Dental Specialists include individuals with:
- Significant jaw misalignment that cannot be corrected with orthodontics alone
- Difficulty chewing, biting, or swallowing
- Chronic jaw or TMJ pain
- Open bite (when teeth don't meet when the mouth is closed)
- Receding chin or protruding jaw
- Sleep apnoea or breathing problems related to jaw structure
- Facial injury or birth defects affecting jaw alignment
Patients should have completed facial growth, which typically occurs by age 16 for females and 18 for males.
What is the recovery time for orthognathic surgery?
Recovery from orthognathic surgery occurs in stages. Initial jaw healing typically takes about six weeks, during which patients gradually return to normal activities. Complete healing can take up to 12 weeks. After the initial healing period, your orthodontist at London Dental Specialists will continue aligning your teeth with braces. The entire treatment process, including pre-surgical orthodontics, surgery, and post-surgical orthodontics, may take 18-24 months to complete.
Is orthognathic surgery painful?
Orthognathic surgery is performed under general anaesthesia, so patients do not experience pain during the procedure. Following surgery, patients can expect some discomfort, swelling, and bruising, which is managed with prescribed pain medication. Most patients report that the discomfort is less than anticipated and typically subsides significantly within the first week. The team at London Dental Specialists provides comprehensive post-operative care instructions to minimise discomfort during recovery.
Will I be able to speak normally after jaw surgery?
Initially after orthognathic surgery, speaking may be challenging due to swelling and adjusting to your new jaw position. While your jaws may be secured with elastic bands rather than being wired shut, it's still beneficial to attempt speaking to aid in returning to normal oral function. Most patients notice speech improvements within 2-3 weeks, with complete return to normal speech patterns within 6-8 weeks. Speech therapy is rarely required but can be arranged through London Dental Specialists if necessary.
What dietary restrictions will I have after orthognathic surgery?
Following orthognathic surgery at London Dental Specialists, patients progress through several dietary stages:
- Liquid diet (1-2 weeks): Clear broths, smoothies, and nutritional supplements
- Pureed diet (2-4 weeks): Blended foods with a smooth consistency
- Soft diet (4-6 weeks): Well-cooked pasta, scrambled eggs, fish, and soft fruits
- Normal diet (after 6 weeks): Gradual return to regular foods as comfort allows
Our team provides detailed nutritional guidance to ensure proper healing and maintenance of nutritional requirements throughout recovery.
Will orthognathic surgery change my appearance?
Yes, orthognathic surgery will change your facial appearance, typically in ways that enhance facial balance and harmony. The extent of change depends on the specific procedures performed and your individual facial structure. At London Dental Specialists, our surgical planning includes detailed imaging and discussions about expected aesthetic outcomes. Most patients report positive changes to their profile, facial proportions, and smile aesthetics following surgery.
What are the potential risks and complications of orthognathic surgery?
As with any surgical procedure, orthognathic surgery carries some risks. These may include:
- Temporary numbness or altered sensation in the lips, cheeks, or gums
- Infection (rare with proper care)
- Bleeding
- Relapse (movement of the jaw back toward its original position)
- TMJ (temporomandibular joint) issues
- Need for additional procedures
At London Dental Specialists, our experienced surgical team takes every precaution to minimise these risks, and we provide comprehensive pre-operative and post-operative care to ensure the best possible outcomes.
How should I prepare for orthognathic surgery?
Preparation for orthognathic surgery at London Dental Specialists typically includes:
- Completing pre-surgical orthodontic treatment (usually 12-18 months)
- Comprehensive imaging and surgical planning
- Pre-operative consultations with your surgeon and anaesthetist
- Arranging time off work or school (typically 2-3 weeks)
- Preparing your home for recovery (soft foods, extra pillows for elevated sleeping)
- Arranging for someone to help you during the initial recovery period
- Following pre-operative instructions regarding medications and fasting
Our team provides detailed guidance to ensure you are fully prepared for both the surgery and recovery period.
