After a crash, most people write down the neck, back, and shoulders first. The jaw often gets left out, even when it has changed. Jaw ache, clicking, a sense that your teeth no longer meet the same way, or trouble opening wide can all be worth recording. This article is educational only. It does not explain what any single symptom means, and only an examining provider can do that.
The jaw joints sit just in front of your ears, and the muscles that move them connect to the neck and head. When the head and neck move fast, the jaw can be affected even if it never struck anything. Some people notice the change within a day. Others notice it a week later, when they bite into something tough or yawn wide.
What to watch for
Start with simple, observable things. Note whether your mouth opens as far as it did the week before. Try opening wide and see whether the jaw drifts to one side. Notice whether you hear clicking, popping, or grinding, and whether it happens on opening, closing, or both. Write down whether chewing gum, biting an apple, or talking for a long stretch sets it off.
Then note the feeling. Is it a dull ache in front of the ear, a tight band along the cheek, or a sharp twinge when you bite down? Does it reach your temples, your ear, or your teeth? Does it wake you at night, or do you clench more when you are stressed? Use your own words, and keep the same words each time you write about it so the pattern stays clear.
Teeth, sleep and clenching
Some people discover after a crash that they clench or grind more than before. Others notice the teeth feel different when they close, or that a filling or crown seems higher than it used to. Record these details with the date. A morning note saying your jaw feels tired and your temples ache is more useful than a vague remark that something feels off.
Sleep matters too. Write down whether you wake with a sore jaw, whether you sleep on one side, and whether your pillow pushes your jaw forward or down. If a partner or family member has mentioned grinding or noises at night, write down what they described and who told you.
Other things to record
Keep a short list of anything that makes the jaw better or worse. Warm packs, soft foods, resting the jaw, or gentle stretching may already be part of your routine. Write down what you tried, how long you did it, and what happened. This helps the examining provider understand your history without guessing.
Also list any dental visits since the crash, any provider you have seen about the jaw, and any dental work done in the past year. If you have had jaw problems before, note the year and how they were handled. You do not need to remember everything in one sitting. Add to the list as details come back to you.
Bringing it to the exam
Bring your notes to your first visit and read them aloud if that helps. Mention the jaw even if it seems minor. Many people wait to say something because they think the symptom is too small to matter. The examining provider decides what is relevant, and a complete list gives them more to work with.
Your jaw notes can sit beside the rest of your crash record: the date of the crash, where you were sitting, what you felt in your neck and head, and what you have already tried. Keep the file somewhere you can find it, and update it on the same day each week so the entries stay comparable.
If your jaw locks, you cannot close your mouth, or you have sudden severe pain with numbness or weakness, do not wait for a scheduled appointment. Seek urgent medical care right away.
