ST. LOUIS METRO - You can talk through the morning meeting, but lunch is another matter. Biting into a sandwich hurts. One side of your jaw feels tired before you finish eating. Since the crash, you have been choosing food that takes less chewing without quite deciding whether that counts as a reason to get examined.
It belongs in the appointment conversation. For someone trying to arrange care this week, the practical question is where to start: a dentist, a medical office or a setting equipped to assess an urgent injury. You do not need to identify the injured structure before making that call. You do need to describe the change.
Start with eating, not a label
The National Institute of Dental and Craniofacial Research describes temporomandibular disorders as conditions involving the jaw joint and the muscles that move it. Symptoms can include chewing pain, stiffness, limited movement or locking. An injury can contribute to some of these disorders, but jaw pain has other possible causes, and diagnosis can be difficult. The letters TMJ name the joint; they do not establish what is wrong. [Source: National Institute of Dental and Craniofacial Research](https://www.nidcr.nih.gov/health-info/tmd).
That distinction matters on the phone. Saying you think you have TMJ supplies a theory. Saying that chewing has hurt since a collision supplies a symptom and a timeline. Adding that one tooth hurts, that your mouth will not open normally or that your teeth meet differently gives the person handling the call something more useful to relay.
Describe only what you have noticed. You do not have to keep biting down, stretch your mouth wide or reproduce the pain to make the report convincing. An ordinary meal may already have given you enough information to explain the problem.
Give the office enough information to route the call
A useful opening is straightforward: you were in a crash on a particular date, you now have pain when chewing, and you want to know whether that office can evaluate it. Mention any known blow to the face or mouth. If you do not remember one, say that instead of filling in the gap.
A dental office will need to hear about tooth damage or pain centered on a tooth. A medical office needs to hear about the collision and any other symptoms accompanying the jaw complaint. Neither call should reduce the story to a request for a routine cleaning or a routine neck appointment.
Ask whether a clinician can review the symptoms to determine the appropriate setting and timing. Appointment availability and clinical urgency are different questions. An opening next Thursday does not, by itself, establish that Thursday is an appropriate time to be examined.
Across the St. Louis metro, a referral may also mean another drive and another absence from work. Before leaving for an appointment, confirm that the office evaluates jaw complaints following injuries. If it recommends another service, ask for the name of the service and how to reach it. A general instruction to see someone else leaves too much unfinished.
Some changes need prompt assessment
After facial trauma, a changed bite, difficulty opening the mouth, swelling or new numbness in the lower lip or chin can occur with a jaw fracture. These findings do not prove a fracture, but they warrant prompt clinical assessment rather than being treated as ordinary soreness. NHS Lanarkshire identifies these features in its guidance on lower-jaw injuries.

Put those changes at the beginning of the call. Do not bury them after a discussion of scheduling preferences. If you have already booked a visit for later in the week and something changes, the earlier booking is not a substitute for reporting the new symptom.
Leave with a clear next step
At the visit, explain what eating was like before the collision and what it is like now. Be specific about older jaw trouble or recent dental work. An accurate starting point helps the examiner assess the change without assuming that every symptom began with the crash.
Before leaving, ask what the examination established, what remains uncertain and who handles the next step. If a referral is recommended, clarify whether the office sends it or you arrange it. This is educational context, not a diagnosis. For this week's decision, the useful starting point is concrete: chewing has changed, and the office needs to hear how.
