Understanding jaw and tmj injury
Jaw and temporomandibular joint (TMJ) injuries can result from direct impact to the face or jaw, or from the same whiplash-type forces that cause neck injuries — the jaw joint can be strained by rapid head movement even without direct impact. Classification depends on the specific diagnosis: a muscular or ligamentous strain around the jaw is generally treated similarly to other soft tissue injuries, a jaw fracture generally is not, and joint derangement or disc displacement within the TMJ may not be. A dental or maxillofacial specialist's assessment is usually needed to properly diagnose a TMJ injury.
Common symptoms
Symptoms can take hours or days to appear after a crash. Getting them assessed and documented early matters for your recovery — and for your claim.
- Jaw pain, particularly when chewing or talking
- Clicking, popping or locking of the jaw joint
- Reduced ability to open the mouth fully
- Headaches or facial pain associated with jaw symptoms
- Tenderness around the jaw joint or surrounding muscles

How we help
A free claim check can explain how a TMJ or jaw injury generally fits into a CTP claim, and why a dental or maxillofacial specialist assessment matters for a proper diagnosis. Where symptoms are persistent or the diagnosis suggests joint derangement rather than simple muscular strain, we'll connect you with an independent lawyer.
Getting the right treatment
A dentist or maxillofacial specialist gives the clearest diagnosis for a jaw or TMJ injury, alongside your GP, who can complete the Certificate of Fitness. Physiotherapy with a jaw-specific focus can help some TMJ presentations. See doctors and allied health for CTP claims for help finding the right providers.

Need a doctor who understands CTP claims?
Your claim runs on medical evidence, so the doctor you see matters. If treatment is what you need, we can refer you to a doctor or allied health provider experienced with CTP claims.
- A doctor experienced with CTP claims — for diagnosis, a treatment plan and your Certificate of Fitness, which records your injuries and your capacity for work.
- Allied health such as physiotherapy, psychology and exercise physiology, for the treatment your injuries need.
- Free, with no obligation. We'll tell you if a provider we refer you to is connected with us, and you can always choose your own.
The CTP insurer generally pays for treatment that is reasonable and necessary for your accident injuries. It decides what's approved, and its decisions can be reviewed.
What matters for your claim
- 1Get assessed by a dentist or maxillofacial specialist for an accurate TMJ diagnosis
- 2Distinguish muscular strain from joint derangement or disc displacement in your records
- 3Keep records of any imaging (such as an MRI of the jaw joint) if performed
- 4Document impact on eating, speaking and daily function
- 5A whole person impairment assessment is relevant if the injury is confirmed non-threshold and ongoing
Getting the right evidence
If you have jaw pain, clicking, or difficulty opening your mouth fully after an accident, see a dentist or your GP for referral to a specialist — jaw injuries are easy to overlook alongside more obvious symptoms like neck pain.
