Medically Reviewed by Dr. Bradley Eli
If you have ever had jaw soreness, headaches, or a dull, persistent ache in your face that does not seem to make sense, you may have been told it is just stress, or maybe TMJ. But there is an entire dental specialty built around figuring out what is actually going on in cases like this. We sat down with Dr. Bradley Eli, an orofacial pain specialist who has spent more than three decades treating complex head, neck, and jaw pain, to understand how this field works and where clenching and grinding fit into the picture.
What Is Orofacial Pain, and How Is It Different From a Toothache or TMJ?
Dentistry traditionally focuses on teeth and the structures directly connected to them, and for a long time, TMJ problems were approached the same way, through occlusion, meaning how the teeth fit together. According to Dr. Eli, that approach worked for some patients but left many others without answers. Those patients would be referred to neurology, then to ear, nose, and throat specialists, sometimes seeing five or six different specialties before anyone found a clear explanation. Orofacial pain developed as its own field to serve exactly this group, people whose pain did not fit neatly into any one specialty's usual model.
The Patients Who End Up in an Orofacial Pain Specialist's Office
Dr. Eli described a wide range of patients who typically reach this level of care. Some have complex migraine or headache patterns that combine multiple types of head pain. Others are classic TMJ patients dealing with clicking, popping, and tooth grinding severe enough to damage dental work. Some have gone through a series of treatments for tooth pain, antibiotics, a root canal, even extraction, and still have pain where the tooth used to be. Others have tried sinus surgery, facial procedures, or jaw surgery and still have unresolved pain or sensations afterward. As Dr. Eli put it, these are often people who have gone through "a ladder of care" that eventually runs out of rungs.
None of this is a checklist for self-diagnosis. If any of this sounds familiar, it is worth bringing to a dentist or physician, not something to work out on your own from an article.
Headaches Are Not All the Same
There are roughly 138 definable headache disorders, Dr. Eli explained, though most are extremely rare. The most common by far is tension-type, or muscle overuse, headache. Diagnosis tends to come from how a patient describes the pain: its location, when it shows up during the day, and its character.
Dr. Eli was careful not to call the location a direct cause, but he did describe some general patterns. Pain at the temples is often muscle-related. Pain behind the eyes tends to point toward sinus issues or a nerve-driven vascular pattern like migraine. Pain across the forehead is more often connected to the upper neck. People who wake up with temple pain, he noted, are frequently clenching or grinding overnight, and addressing that nighttime behavior often improves the headache pattern alongside it.
Where Clenching and Grinding Fit Into the Picture
Dr. Eli breaks bruxism, the general term for clenching and grinding, into three rough categories. The first is situational, someone clenching temporarily because of pain somewhere else in the body, like a sprained ankle, that resolves once the underlying issue does.
The second, and most common, is what he calls typical grinders, people whose dentist notices wear on the teeth and who have developed a habit of holding their teeth together that they are often not fully aware of.
The third is a smaller, more severe group, what he calls pathologic para-function, clenching and grinding intense enough to chip or break teeth and require significant dental work.
One detail worth knowing: about half of the people in that severe group do not have facial muscle pain at all, according to Dr. Eli. He compared it to a long-distance runner who does not get leg pain because the muscles involved have become very well conditioned to the activity.
So the assumption that clenching always shows up as sore muscles does not hold true across the board, even though it is a reasonably reliable sign in the more typical, moderate group.
Daytime vs. Nighttime Clenching
According to Dr. Eli, it is rare for someone to have only a daytime pattern or only a nighttime one, most people who clench or grind do some version of both. Nighttime grinding tends to be more intense.
Daytime clenching is often more about resting tooth contact, teeth held together during focused activities like working at a computer, texting, or driving.
He specifically pushed back on the common belief that this resting contact is normal, noting it is actually a misconception that gets reinforced over time rather than how a relaxed jaw is supposed to work.
The Migraine and Jaw Connection
Migraine and jaw clenching often show up together, and Dr. Eli described why. The trigeminal nerve is responsible for both facial sensation and jaw muscle function, and irritation to that nerve can affect both systems at once, migraine can aggravate the nerve, and nerve irritation can in turn increase jaw muscle activity, creating what he called a snowballing effect between the two.
Why Awareness Comes First
When asked what actually helps with chronic clenching and grinding, Dr. Eli was direct: "There's nothing stronger to treat a behavior problem than behavioral change. In order to make a change in behavior, you have to be made aware of the behavior." He described biofeedback, broadly, as using your own body's feedback to prompt a change you would not otherwise notice needing to make.
When asked specifically about devices like ClenchAlert that give real-time feedback when clenching occurs, Dr. Eli described it as a tool "uniquely made to give the biofeedback," explaining that a buzzing cue when you close down helps you notice the behavior and start to adjust it. He contrasted this with older daytime mouthpiece approaches, which he said people tend to adapt to and bite through just as hard as anything else, partly because they interfere with talking and are harder to wear consistently.
His emphasis throughout was on consistency, that repeated, simple awareness cues, used regularly, are what actually help someone reposition a habit over time, not any single tool on its own.
This reflects Dr. Eli's professional observations shared in this interview, not a formal clinical endorsement or a claim that any device treats or cures bruxism. ClenchAlert® does not stop clenching for you. The vibration provides feedback that may help you notice and interrupt the pattern yourself.
When Should You See a Specialist?
Dr. Eli's patients are typically people who have already tried other avenues, general dentistry, other medical specialties, without a clear answer. If you are dealing with persistent jaw or facial pain, headaches that do not respond to typical care, restricted jaw opening, or symptoms that have lingered despite treatment, that is worth bringing to a dentist, physician, or an orofacial pain specialist.

Frequently Asked Questions
What is orofacial pain, and how is it different from TMJ?
Orofacial pain is a specialty that developed to treat complex head, neck, and jaw pain that does not resolve through the traditional dental approach to TMJ, which focuses on how the teeth fit together, or through other single specialties like neurology.
Does clenching always cause facial muscle pain?
Not necessarily. Dr. Eli noted that in his experience, roughly half of the people with the most severe clenching and grinding patterns do not have facial muscle pain, since heavily used muscles can become well conditioned to the activity, similar to how a trained runner does not get sore from running.
Is daytime clenching different from nighttime grinding?
Most people who clench or grind do some version of both rather than only one. Nighttime grinding tends to be more intense, while daytime clenching is often lower-level resting tooth contact that can go unnoticed.
Why do some headaches happen behind the eyes and others at the temples?
Dr. Eli described general patterns rather than strict rules: temple pain is often muscle-related, pain behind the eyes often points to sinus issues or a vascular pattern like migraine, and forehead pain is more often connected to the upper neck. These are patterns worth discussing with a specialist, not a self-diagnosis tool.
Can biofeedback help with clenching and grinding?
Dr. Eli described biofeedback as a way of using your body's own signals to become aware of a behavior you would not otherwise notice, which he considers a meaningful tool for behavior change when used consistently.
Start With Awareness
As Dr. Eli put it, awareness is the first step toward lasting relief. If jaw pain, headaches, or facial discomfort have been part of your life without a clear explanation, that is worth bringing to a specialist who can look at the full picture, not something to piece together alone.
