You have worn the splint. You have had your bite adjusted. Maybe you have tried Botox, or soft foods, or physical therapy for your jaw. Some of it helped for a while. Then the clicking came back, or the morning headache, or that ache in front of your ear that spreads up into your temple.
If that is where you are, there is one question worth asking. Has anyone looked at your neck?
Your jaw and the top of your neck report to the same place
Sensation from your jaw, your teeth, and most of your face travels along the trigeminal nerve. Sensation from the top of your neck travels along your first three cervical nerves, C1, C2, and C3. Those signals do not stay separate. They arrive at the same relay station in your brainstem, a long column of cells called the trigeminocervical nucleus.
A 2022 review in Medicina mapped this in detail (Sedy et al., Medicina 2022;58(10):1324). The upper three cervical nerves connect densely into that shared column. The fourth cervical nerve and everything below it does not. The connection belongs specifically to the top of your neck, and it runs in both directions. Jaw trouble can produce neck pain. Trouble at the top of your neck can produce pain your brain reads as jaw, ear, temple, or cheek.
What the research shows when jaws and necks are studied together
A 2020 systematic review in the Journal of Clinical Medicine pooled 32 observational studies covering 1,903 people with temporomandibular disorders, the clinical name for problems of the jaw joint and the muscles that move it (Cuenca-Martinez et al., J Clin Med 2020;9(9):2806). Across six of those studies and 548 patients, neck disability scores tracked with jaw disability scores at a moderate, consistent level. The review also found reduced neck range of motion and more tenderness in the muscles at the top of the neck in people with jaw disorders.
One measure went the other way. Head and neck posture, the forward carriage of the head, showed no meaningful difference between people with jaw disorders and people without. Posture is not the variable doing the work here.
The authors rated the quality of the included studies as fair to poor and asked that the findings be read with caution. A larger set of higher-quality studies could confirm how tight this relationship really is.
Treating the neck changes what the jaw feels
A 2024 systematic review and meta-analysis in the Journal of Oral Rehabilitation examined seven randomized controlled trials of cervical treatment in adults with muscle-driven jaw pain (Bednarczyk, Proulx, and Paez, J Oral Rehabil 2024, DOI 10.1111/joor.13671). Upper cervical manual therapy, on its own or paired with a neck exercise program, improved pain intensity, tenderness in the jaw muscles, and how far people could open their mouths.
Those trials measured short-term results. Whether the gains hold across years is the question the next round of research needs to answer.
Why a splint can help and still leave you stuck
A splint does real work. It changes how your teeth meet, unloads the joint, and takes pressure off muscles that have been working overtime for years. For many people that is enough.
When it is not enough, the usual reason is that the splint is doing everything it can at one end of a problem with two ends. If the top of your neck is holding a misalignment, signals keep arriving at that shared relay station all day long. The jaw gets quieter. The system does not.
What we assess at Atlas
The top of your neck is the part of this we are trained to measure precisely. That assessment is called the Blueprint Spinal Analysis, and it has three parts: a hands-on exam to locate tight muscles, spinal restrictions, and inflammation, an AI-analyzed 3-D postural evaluation, and comprehensive digital spinal X-ray analysis.
The imaging carries the most weight. Orthospinology, the Upper Cervical technique used at Atlas, measures the position of your Atlas, the top bone in your neck, in degrees and millimeters off your own images. Those numbers set the direction, angle, and depth of your correction. Every problem has a cause, and we never guess about yours.
This sits alongside your dental care
Upper Cervical care addresses the other end of the same neural pathway your dentist is already treating, and the two work well together. Your dentist is welcome to call us directly at 254-304-7474.
