What is the difference between oral surgery and oral medicine?

Oral & Maxillofacial Surgery handles surgical treatment such as extractions (especially impacted wisdom teeth), corrective jaw surgery, and oral cancer, while Oral Medicine handles nonsurgical areas such as TMJ (jaw joint) disorders, teeth grinding, and oral mucosal diseases. The right specialty depends on your symptoms, so check before booking.

My mouth often gets sores that are slow to heal. Could it be oral cancer?

Ordinary mouth ulcers usually heal within 1 to 2 weeks. If a sore in the same spot does not heal for 3 weeks or more, or comes with a hard feel or white or red changes with irregular borders, it should be examined to rule out oral cancer. Whether or not it hurts cannot decide this.

The pain got worse a few days after extraction. Is that normal?

If pain gets worse over time and comes with a bad smell, it may be dry socket, where the blood clot has come out, and you should go back. Rather than waiting for it to heal on its own, it is safer to get treatment at the clinic that did the extraction.

Can I have a tooth extracted while taking osteoporosis medication or during cancer treatment?

The plan depends on your medications and stage of treatment. Bisphosphonate osteoporosis drugs can affect jawbone healing at the extraction site, and dental checkups and any needed extractions before cancer treatment help prevent complications. Always telling the dentist about your medications and treatment history is the safe procedure.

What is oral surgery?

Oral & Maxillofacial Surgery is a dental specialty responsible for surgical diagnosis and treatment of the mouth, jaw, and face [1]. Typical areas are impacted wisdom tooth extraction, corrective jaw (orthognathic) surgery, diagnosis and treatment of oral cancer, and treatment of injuries [1]. Nonsurgical areas such as TMJ (jaw joint) disorders and oral mucosal diseases are handled by Oral Medicine, so the right specialty depends on your symptoms [1].

DentStat analyzed 1,124 patient comments on oral surgery in YouTube dental content (507 of them questions). The most frequent questions were about telling mouth ulcers from oral cancer (70), care after extraction (68), and double jaw and facial contouring surgery (57) [4].

When should a sore in the mouth be examined?

Ordinary mouth ulcers usually heal within 1 to 2 weeks [1]. On the other hand, if a sore in the same spot does not heal for 3 weeks or more, feels hard, or comes with white or red changes with irregular borders, it should be examined to rule out oral cancer [1]. Having no pain is not a reason for reassurance, and whether it hurts cannot serve as a standalone criterion [1]. Chronic irritation from a broken tooth or an ill-fitting restoration can also cause mucosal lesions, so these should be checked as well [1].

Telling mouth ulcers from oral cancer was the most asked-about theme in the comment analysis (70), and many comments described how hard it is to judge on one’s own [4].

How should I care for the site after an extraction?

Right after extraction, biting on gauze with steady pressure to stop bleeding and preserving the blood clot that forms in the socket are the basics of recovery [1]. Vigorous rinsing, using straws, and smoking can dislodge the clot, so you are advised to avoid them [1]. Pain and swelling usually decrease over several days [1].

If pain gets worse over time and comes with a bad smell, it may be dry socket, and you should go back [1]. In many cases, extraction is covered by National Health Insurance [2]. Wisdom tooth extraction is covered in detail in the wisdom tooth guide.

Where are impacted wisdom teeth removed?

Complex cases that are close to the nerve canal or fully impacted are sometimes referred to higher-level institutions such as university hospitals, but extractions are also done at dental hospitals and dental clinics with board-certified oral and maxillofacial surgeons [1]. You can check the regional distribution of dental clinics with these specialists on DentStat region pages, based on public data from the Health Insurance Review & Assessment Service (HIRA) [3].

When is double jaw or facial contouring surgery considered?

Double jaw (orthognathic) surgery is considered for jawbone position problems that cannot be solved by orthodontics alone, such as skeletal malocclusion [1]. Whether to have surgery and how it is done are decided based on skeletal analysis, and confirming the explanation of the recovery period and possible side effects beforehand is an important step [1]. Related questions totaled 57, many about the decision to have surgery and the recovery process [4].

What should I tell the dentist if I have a systemic illness?

Bisphosphonate osteoporosis drugs can affect jawbone healing after extraction, so disclosing that you take them is important [1]. If you are about to start cancer treatment, completing a dental checkup and any necessary extractions beforehand helps prevent infection complications [1]. Chronic conditions such as diabetes and your medications in general can affect the surgical plan, so bringing a list of your medications to the consultation is the safe procedure [1].
