A knock to the head can change how your jaw, teeth, and the muscles around your face feel for days afterward. Many people notice it first at the dinner table. A bite of bread feels heavier than it should, or chewing gum leaves a dull ache above the ear. This note is for people in the St. Louis metro who want to keep a simple record before a visit, so the person examining them has something concrete to read.
This is not a diagnosis, and it does not tell you what is causing your symptoms. It is a way to organize what you already notice so the details do not blur together by the time you sit down with a clinician.
Why chewing gets its own line
Chewing uses the jaw, the muscles along the sides of the head, and the nerves that run through them. Some people find that a head injury makes these muscles feel tighter or more tender, and that the first clear sign is pain or fatigue when eating certain foods. Others notice clicking, a feeling that the jaw does not close evenly, or a headache that builds during a long meal. Because these signs are easy to dismiss as tired muscles, they often go unrecorded.
What to write each time you eat
Keep a small notebook or a note on your phone. Each time you eat, write the time, the food, and whether it was soft, chewy, crunchy, or sticky. Chewy items such as bagels, steak, and dried fruit often show a difference sooner than soup or rice. Note which side you chewed on, if you noticed yourself favoring one. Add a line for how long the meal lasted and whether you had to stop and rest your jaw.
Then describe the discomfort in your own words. Write whether it felt mild, dull, sharp, or tired, and say where you felt it: the temple, the cheek, the ear, the back of the neck, or the front teeth. Describe the feeling, not just the location. A tight band feels different from a stabbing point, and both matter to the person who will examine you.
Gum, snacks, and hard foods
Gum is worth a separate line because it creates steady, repeated jaw movement without a meal to finish. Log how many minutes you chewed gum and what happened afterward. Do the same for hard candy, ice, nuts, raw vegetables, and crusty bread. If you cut food into smaller pieces or stopped eating something entirely, write that down too. Changes in what you avoid are useful clues, even if you do not know why you avoid them.
Pay attention to sounds you can hear from inside your head. A click, a pop, or a grinding feeling when you open wide should be logged with the food you were eating and the time of day. Note whether the sound came with a headache, dizziness, or a change in how your teeth fit together when you close.
Patterns that help a visit
After three or four days, read the notes back and look for repeats. Did a certain food always bring the ache on? Did the ache build later in the day, after many meals, or ease by evening? Did your sleep change, and did you wake with a sore jaw? Circle the entries that surprised you. Those are often the ones worth raising first.
Bring the log to your visit and read the key lines aloud. If you are seeing a dentist, a primary care clinician, or a headache specialist, say which symptoms started after the knock and which were already present. Note any medicines or supplements you took, the dose, and the time, so they can be weighed against what you recorded.
When not to wait
A log is for organizing, not for waiting. If chewing brings on a sudden severe headache, weakness on one side of the face, slurred speech, confusion, vision loss, vomiting, or trouble swallowing or breathing, get emergency care now rather than writing it down first. If your jaw locks open or shut, or you develop fever with facial swelling after an injury, contact a clinician the same day.
Whatever you find, keep the record simple and factual. Dates, foods, times, and plain words will do more for your visit than a long summary, and they remain useful if you decide to return to the notes later.
