A wisdom tooth that will not erupt properly, a jaw that clicks and locks, or a missing tooth that needs an implant can involve more than routine dental treatment. What is oral and maxillofacial surgery? It is a dental specialty focused on diagnosing and treating conditions affecting the mouth, teeth, jaws, face, and related structures through surgical care.
For many patients, hearing the word surgery can feel intimidating. In practice, oral and maxillofacial surgery ranges from common procedures such as complex tooth extractions to carefully planned treatments involving implants, bone grafting, facial trauma, or jaw reconstruction. The right approach depends on the condition, your overall health, your comfort needs, and the long-term result you want to achieve.
What Is Oral and Maxillofacial Surgery Used For?
Oral and maxillofacial surgery, often shortened to OMFS, addresses problems that cannot always be resolved with routine restorative or preventive dentistry alone. The goal may be to relieve pain, control infection, restore chewing function, replace missing teeth, improve jaw movement, or protect surrounding bone and teeth.
A general dentist may identify an issue during an examination or X-ray and recommend a surgical consultation. In many cases, surgery is only one part of a larger treatment plan that may also include periodontal care, root canal treatment, orthodontics, crowns, bridges, or implant-supported restorations.
Common reasons a patient may need oral and maxillofacial surgery include:
- Impacted wisdom teeth or other teeth that cannot erupt normally
- Teeth that are severely damaged, infected, or difficult to remove
- Missing teeth requiring dental implants and, in some cases, bone grafting
- Jaw pain, temporomandibular joint concerns, or bite-related jaw problems
- Cysts, suspicious lesions, or infections affecting the jaw or soft tissues
- Facial injuries involving the teeth, jaw, or facial bones
- Preparation for dentures when bone shape or volume affects fit and stability
Not every concern requires surgery. For example, a painful tooth may be saved with root canal treatment and a crown, while another tooth may be too compromised to restore and may be better removed and replaced. A thorough assessment helps clarify which option protects your oral health most effectively.
Who Performs Oral and Maxillofacial Surgery?
Oral and maxillofacial surgeons are dentists with additional hospital-based surgical and anaesthesia training after dental school. Their specialty training prepares them to manage surgical conditions involving the mouth, jaws, and face, including more complex cases and patients with medical considerations.
Your family dentist remains an essential part of the process. They may coordinate examinations, digital imaging, referrals, restorative planning, and follow-up care. When treatment happens within a multidisciplinary clinic, the clinicians involved can work from the same diagnostic information and plan the surgical and restorative stages together. This can be especially helpful for implant treatment, where the position of the final crown matters before the implant is placed.
At ORIS Dental Clinics, patients can discuss surgical needs alongside their broader dental plan, rather than treating an extraction, bone graft, or implant as an isolated event. Coordinated care can reduce uncertainty and help ensure that each step supports the next one.
Common Oral and Maxillofacial Procedures
Wisdom tooth removal
Wisdom teeth are the last molars to develop and often appear in the late teens or early twenties. Some erupt normally and are easy to clean. Others remain partly or fully trapped in the jawbone, press against neighbouring teeth, contribute to repeated gum inflammation, or develop decay in a hard-to-reach area.
Surgical removal is often recommended when a wisdom tooth is causing symptoms or is likely to create future problems. Timing matters. Removing a problematic tooth before roots fully develop can sometimes make treatment and recovery more straightforward, but early removal is not automatically necessary for every patient.
Complex extractions and infection management
A tooth may need surgical removal when it has fractured below the gumline, has an unusual root shape, is fused to bone, or cannot be safely removed through a standard extraction. Severe infections can also require prompt treatment, particularly when swelling spreads or affects swallowing, breathing, or overall health.
If a tooth is removed, the next question is often whether it should be replaced. That decision depends on the tooth’s location, the stability of nearby teeth, bite function, bone health, and your treatment goals. Replacing a missing back tooth may help preserve chewing ability, while replacing a visible front tooth may also be important for appearance and speech.
Dental implants and bone grafting
Dental implants replace a missing tooth root with a small, biocompatible post placed in the jawbone. After healing, the implant can support a crown, bridge, or denture. Implant surgery requires careful planning because the implant must be positioned where there is adequate bone and where the final tooth will function well with your bite.
When bone has thinned after tooth loss, a bone graft may be recommended before or at the time of implant placement. This can add treatment time, but it may create a stronger foundation and improve the predictability of the final result. Digital imaging helps the clinical team assess bone volume, nerve locations, sinus position, and other anatomical details before treatment begins.
Jaw and facial conditions
Oral and maxillofacial surgeons may also treat jaw fractures, facial injuries, cysts, tumours, and conditions that affect jaw alignment. Some bite problems can be managed with orthodontics alone, while severe skeletal discrepancies may require corrective jaw surgery in combination with orthodontic treatment.
These cases are highly individual. The plan may involve several providers and a longer timeline, but the aim is practical: better function, a more stable bite, improved comfort, and protection of long-term oral health.
What Happens Before Surgery?
A surgical consultation is designed to answer the questions that matter before any procedure is scheduled. Your dentist or surgeon will review your medical history, medications, allergies, symptoms, and previous dental treatment. X-rays or 3D imaging may be used to see structures that are not visible during a regular examination.
You should mention medications such as blood thinners, diabetes medications, osteoporosis drugs, or any treatment that affects healing or immune function. Smoking and vaping can also slow healing and increase the risk of complications after extractions, grafts, and implants. This does not mean treatment is unavailable, but it may affect the plan and the instructions you receive.
The consultation should also cover benefits, limitations, alternatives, expected recovery, and costs. Some surgical treatment may be partly covered through dental insurance, while coverage varies widely by procedure and plan. Patients using the Canadian Dental Care Plan should ask how eligibility and coverage apply to their specific proposed treatment. Direct billing, where available, can make the administrative side easier, but it does not replace confirming your personal coverage.
Sedation and Comfort During Oral Surgery
Comfort is a legitimate part of surgical planning, particularly for patients with dental anxiety, a strong gag reflex, or a procedure expected to take longer. Local anaesthetic is used to numb the treatment area. Depending on the procedure and your health history, additional options may include nitrous oxide or other forms of sedation.
Sedation is not the best choice for everyone. It requires medical screening, informed consent, and practical preparation, including arranging a responsible adult to take you home when required. Your provider will explain fasting instructions, medication adjustments, and what to expect on the day of treatment.
Clear communication can make a significant difference. Let the team know if you have had a difficult dental experience, feel anxious about injections, or worry about pain after surgery. There are often ways to adjust the pace of care and build a plan that feels manageable.
Recovery: What Patients Can Expect
Recovery varies considerably. A simple extraction may involve mild soreness for a few days, while multiple wisdom tooth removal, grafting, or implant surgery can require more planning and a longer healing period. Swelling, tenderness, minor bleeding, and temporary changes in eating habits are common after many procedures.
Your post-operative instructions may include using gauze as directed, resting, choosing soft foods, maintaining careful oral hygiene, taking prescribed or recommended medication, and avoiding smoking, alcohol, vigorous rinsing, and strenuous exercise for the advised period. Following these instructions protects the blood clot and supports normal healing.
Contact your dental team promptly if pain worsens after initially improving, bleeding does not settle, swelling becomes severe, you develop a fever, or you experience numbness or other symptoms that concern you. Difficulty breathing or swallowing requires urgent medical attention.
When to Ask for a Surgical Assessment
You do not need to wait until pain becomes severe to ask about oral surgery. A consultation can be useful when a tooth repeatedly becomes infected, a wisdom tooth is difficult to clean, you are considering implants, or you have persistent jaw symptoms or a lesion that has not healed.
The most reassuring next step is often simply getting clear answers. With a careful assessment and a treatment plan built around your health, comfort, and priorities, oral and maxillofacial surgery can become a practical path toward eating, speaking, smiling, and feeling well again.
