What do patients ask about most?
Analysis of 14,962 patient question comments on YouTube content about TMJ and face (collected July 6, 2026).
What is a TMJ disorder?
The temporomandibular joint (TMJ) sits between the lower jawbone and the skull and handles the movements of opening and closing the mouth [1]. When problems develop in this joint and the surrounding muscles, jaw pain, joint noises (clicking), and limited mouth opening can appear, and these are collectively called TMJ disorders [1].
DentStat collected YouTube patient comments on TMJ and face topics, removed unrelated videos (posture correction, cosmetic surgery, and similar), and analyzed the remaining 14,962 comments. There were 13,839 valid signals, and the most mentioned themes were jaw noises (1,558), facial asymmetry (1,085), double jaw and facial contouring surgery (1,083), and self-exercise and massage (1,052) [4]. This guide organizes facts confirmed by public sources in that order of interest.
My jaw makes noises but doesn’t hurt. Do I need treatment?
Simple joint noises without pain or limited opening sometimes do not need immediate treatment [1]. However, if the sound changes or pain or limited opening begins, it needs a diagnosis, so the usual approach is to watch for changes in symptoms [1].
In the patient comment analysis, mentions of jaw noises were the most common at 1,558, and questions such as “It doesn’t hurt, so do I need to see a doctor?” came up repeatedly [4].
Which department should I see for jaw pain?
Diagnosis and treatment of TMJ disorders fall under dentistry. More specifically, Oral Medicine handles diagnosis, occlusal splints, and conservative treatment, while Oral & Maxillofacial Surgery handles reducing jaw dislocations and surgical treatment [1]. Repeated dislocation, where the jaw slips out of place, also needs treatment [1].
The comment analysis also confirmed that some people first visit other departments because of related symptoms such as tinnitus, headaches, and neck pain, with 567 mentions about which department to see and cost [4].
Is self-exercise or massage alone enough?
The general treatment principle for TMJ disorders is to start with conservative methods such as habit correction, self-exercise, physical therapy, medication, and occlusal splints [1]. Self-exercise and massage are aids to conservative treatment, and if pain increases or symptoms worsen during exercise, stop and consult a dentist [1].
The comment analysis found 1,052 mentions of self-exercise and massage, with many questions about whether people were doing it correctly and when to stop [4].
What treatments are there for teeth grinding and clenching?
Grinding and clenching are considered factors that place continuous strain on the jaw joint and chewing muscles [1]. Management includes wearing an occlusal splint and managing habits and stress, and an occlusal splint requires regular checks and adjustments after it is made [1].
There were 1,027 mentions of grinding and occlusal splints, mostly questions about how long the device’s effect lasts and how to care for it [4].
Do dentists also treat facial asymmetry?
Facial asymmetry has many causes, from muscle and habit factors to skeletal factors, and the approach differs by cause, so a detailed diagnosis comes first [1]. Skeletal problems or severe malocclusion are sometimes evaluated by Oral & Maxillofacial Surgery for orthognathic (double jaw) surgery [1]. Double jaw surgery is major surgery that cuts and repositions the jawbones and can cause complications such as altered sensation, so an assessment of indications and a thorough explanation are needed before surgery [1].
In the comment analysis, facial asymmetry was the second most mentioned theme at 1,085, and double jaw and contouring surgery also had 1,083 mentions, showing interest in surgical safety [4].
Is it covered by National Health Insurance?
Some treatment items for TMJ disorders, such as physical therapy and occlusal splints, may be covered (paid in part by Korea’s National Health Insurance), and whether and how much they are covered depends on the diagnosis and detailed criteria [2]. Cosmetic surgery and procedures are not covered [2]. Cost questions were a recurring theme in the comment analysis, and confirming coverage during treatment is the starting point for estimating costs [4].
Information on dental clinics nationwide (number of board-certified specialists, locations, and more) is available on DentStat’s regional pages, based on public data from the Health Insurance Review & Assessment Service (HIRA) [3].

Frequently asked questions
- My jaw clicks but it doesn't hurt. Can I leave it alone?
- Joint noises without pain or limited mouth opening sometimes do not need immediate treatment. However, if the sound changes or pain or limited opening appears, it needs a diagnosis, so people usually have it checked at a dental clinic (Oral Medicine) when symptoms change.
- Which department should I see for jaw pain?
- Diagnosis and treatment of TMJ disorders fall under dentistry. Oral Medicine handles diagnosis and conservative treatment such as occlusal splints, while Oral & Maxillofacial Surgery handles reducing dislocations and surgical treatment. Some people first visit other departments because of related symptoms such as tinnitus or headaches, so the cause needs to be identified.
- Can self-exercise or massage alone cure it?
- Habit correction and self-exercise are used as aids to conservative treatment. However, if pain increases or symptoms worsen during exercise, the usual procedure is to stop and get a diagnosis.
- What is an occlusal splint?
- It is a device worn in the mouth as conservative treatment to reduce strain on the jaw joint and muscles from grinding or clenching. Regular checks and adjustments after it is made are a given, and how and how long to wear it depends on the diagnosis.
- Does National Health Insurance cover TMJ treatment?
- Some items such as physical therapy and occlusal splints may be covered by National Health Insurance, and whether and how much they are covered depends on the diagnosis and detailed criteria. Cosmetic surgery and procedures are not covered.
- When is double jaw surgery done?
- It is surgery evaluated by Oral & Maxillofacial Surgery when there are functional problems such as skeletal malocclusion. It is major surgery that cuts and repositions the jawbones and can cause complications such as altered sensation, so an assessment of indications and a thorough explanation are needed before surgery.
