What This Guide Covers
This guide covers the first days and weeks of new jaw pain: what to do at home and when to call a dentist.
It is written for adults whose jaw started hurting recently, within the last few days or few weeks. That pain often sits in front of the ear, along the cheek, or in the muscles near the temple. It may flare when chewing, yawning, or waking up. The joint involved is the temporomandibular joint, the hinge that connects the lower jaw to the skull. Problems in that joint and the muscles around it are grouped under the term TMD, short for temporomandibular disorders. Many TMDs last only a short time and get better on their own, and most do not steadily worsen [6].
Two things are worth saying before the self-care steps. Nothing here replaces an exam [10]. And this guide does not cover injuries. A blow to the face, a jaw that will not close, or a tooth knocked out of its socket belongs in an emergency room or a dental office the same day, not in a home care plan [5].
Treating New Jaw Pain Like a Sprain
Most new jaw pain behaves like a jaw sprain or strain, which means overworked muscles and an irritated joint that settle with rest [6].
That framing changes what you do first. A sprained ankle is not treated with surgery in week one. It is rested, supported, and eased back into normal use. Jaw pain is often handled the same way, with conservative care first and more involved treatment held in reserve [6]. The JAMSS protocol, a set of early-care instructions written for clinicians treating jaw and muscle sprain or strain, follows that same order [3]. It is built around a speed-to-treat idea, which is that simple care started early gives a strained jaw its best chance to settle before guarding and clenching habits set in [3].
Clinicians who use that protocol organize early care with four letters, M.E.A.T., which stands for movement, exercise, analgesia, and treatment [3]. Movement means keeping the jaw loose instead of braced. Exercise means small motions inside a range that does not hurt. Analgesia means cold first, then moist heat, plus pain medicine when it is safe for you. Treatment means a short-term splint if a dentist decides one is needed. The reason the jaw gets movement rather than a cast is simple: you still have to talk, swallow, and breathe, so the joint cannot be held still the way an ankle can [3].
One limit is worth naming. M.E.A.T. is written for mild and moderate strains, what clinicians call first-degree and second-degree injuries [3]. A more severe injury, the kind that follows a real blow to the face, is a different situation. That needs an in-person exam and imaging, not a home plan [5].
What Overloads a Jaw
Jaw muscles work all day, and for some people they work at night too. A long dental appointment, a stressful stretch at work, heavy gum chewing, a new sleep position, or a run of clenching can overload them. A long appointment with the mouth held wide open, such as a wisdom tooth removal, is one of the more common starting points, which is why dentists ask about recent dental work [3]. Bruxism, the clinical word for teeth grinding or clenching, is another common trigger and often happens during sleep without the person knowing [5]. A cold or a sinus infection can make the same area ache. In many cases no single cause stands out, and the pain still improves with rest and time [6].
Moist Heat, Cold Packs, and Real Rest
Heat and cold both help, and they do different jobs [6]. Moist heat relaxes tight jaw muscles and brings blood flow to the area, so it suits a dull, tired ache along the cheek and temple [3]. A warm, damp washcloth for ten to fifteen minutes, a few times a day, is enough. A cold pack narrows blood vessels and calms sharp pain and a joint that feels hot or swollen [3]. Wrap it in a towel and keep it on for about ten minutes at a time.
Many people alternate: a cold pack during the first day or two, then moist heat once the sharpest pain fades [3]. Rest matters as much as either one [10]. Rest from clenching has a specific meaning. The teeth stay apart when the mouth is at rest, the lips stay together, and the tongue sits behind the top front teeth. Clinicians shorten that to teeth apart, tongue up [3]. Checking that position a few times an hour is one of the highest-value habits in the first week.
Gentle Jaw Exercises in a Pain-Free Range
Gentle jaw exercises give tight muscles a reason to let go, and stretching the jaw muscles gently is part of standard self-care [6]. One rule keeps them safe: move only as far as the jaw travels without pain, then stop. That is the pain-free range [4].
- Rest position. Lips together, teeth apart, tongue behind the upper front teeth. Hold for a few minutes at a time through the day [3].
- Controlled opening. Keep the tongue behind the upper front teeth and open slowly until you feel a stretch but no pain. Hold briefly, then close [4].
- Side to side. Slide the lower jaw slowly toward one side, then the other, staying inside the pain-free range [4].
- Light resistance. Place a thumb under the chin and open slowly against gentle pressure, then close against a finger placed on the front teeth [4].
How Often to Do Them
Short and frequent beats long and hard. Several small sets spread through the day is typical guidance, and these exercises are usually used alongside the rest of the plan rather than on their own [4].
It is worth knowing how strong that evidence is. A 2016 systematic review and meta-analysis in the journal Physical Therapy pooled 58 articles representing 50 studies of exercise and hands-on therapy for temporomandibular disorders [8]. Jaw, posture, and neck exercises came out ahead of other conservative treatments, and hands-on therapy looked useful alone or combined with exercise. The authors also rated most effects as small to moderate and found no high-quality trials, so the honest summary is that gentle jaw exercises are low-risk and probably helpful, not proven to be powerful [8]. Results vary from person to person. If one movement leaves the jaw sorer for more than a few minutes, drop it and mention it at your visit.
What to Change for the First Two Weeks
The first two weeks call for small changes you can keep: softer food, smaller bites, fewer jaw-heavy habits, and attention to warning signs.
Age shifts the picture a little. Teenagers get jaw pain too, often around braces, erupting wisdom teeth, or heavy gum chewing, and the same home care applies. In children under about twelve, jaw pain is less common and is worth a dental look sooner rather than later, since an ear infection or a tooth problem can sit behind it [5]. Adults over sixty with new jaw pain deserve prompt evaluation as well, because other conditions can imitate a strained jaw [10].
Soft Foods and Habits to Pause
Soft foods are not a diet, just a two-week break for the jaw. A simple rule is to avoid anything that makes the pain worse or makes the jaw click, and to cook food soft and cut it small [6]. Eggs, fish, soup, pasta, beans, yogurt, smoothies, and cooked vegetables all work.
- Pause the hard chewers: gum, bagels, crusty bread, tough steak, jerky, hard candy, nuts, and ice [6].
- Skip tall food. Big sandwiches and whole apples force a wide opening.
- Drop the small habits: nail biting, pen chewing, and holding a phone against the shoulder [10].
- Support wide yawns with a hand under the chin so the jaw does not open to its limit [6].
Over-the-Counter Options
Over-the-counter pain relievers are part of standard conservative care for short stretches [6]. The anti-inflammatory group, called NSAIDs, includes ibuprofen and naproxen. They are often chosen when the joint itself feels tender and swollen, because they lower the body chemicals that drive swelling. They tend to do less for pain that comes mainly from tired chewing muscles, so a few days of ibuprofen with little change does not mean nothing will work.
NSAIDs are not harmless, and this is the part most jaw pain articles leave out. The FDA requires a warning that non-aspirin NSAIDs can raise the risk of a heart attack or a stroke, that these problems can happen without warning, and that the risk is higher at higher doses and with longer use [9]. NSAIDs can also cause stomach bleeding and ulcers [9]. Talk to a physician or pharmacist before you start if any of these apply to you: you take a blood thinner such as warfarin, you take blood pressure medicine, you have had a stomach ulcer or a bleed, you have kidney disease, liver disease, or heart disease, or you are pregnant.
Acetaminophen works a different way. It relieves pain but it is not an anti-inflammatory, so it may do less for a joint that feels swollen, even though it avoids the heart risks that come with NSAIDs [13]. It carries its own daily limit and its own liver warning, and going past the labeled dose, including doses hidden in combination cold and pain products, can cause serious liver damage [13].
Whatever you take, use the lowest dose that helps for the shortest run that helps, and do not start a multi-day course on your own [9]. Topical heat patches help some people. None of this fixes a cause. It lowers pain enough for the jaw to rest and for the gentle jaw exercises to be tolerable.
About Drugstore Night Guards
A boil-and-bite night guard from the drugstore is the most common self-treatment for grinding, and during a flare it is a mixed choice. It does cover the teeth, which matters for someone whose main problem is tooth wear from bruxism [5]. It also adds bulk between the teeth, and some people clench harder against it. It is not fitted to your bite, and a poor fit can move teeth over time. That caution applies to any appliance that covers only part of the arch, including a dentist-fitted bite plane, and it is one reason those come with a written wear schedule instead of open-ended use [2]. A dentist-fitted short-term splint sits between drugstore products and a lab-made custom oral appliance [2].
One label point confuses a lot of shoppers. Mouth guards and bite planes are regulated as medical devices, and most reach the United States market through FDA 510(k) clearance [12]. Clearance means the maker showed the device is close enough, or substantially equivalent, to one already sold legally [12]. That is not the same as FDA approval, which comes from a separate and stricter review called premarket approval, or PMA, and is used for higher-risk devices [12]. Neither word tells you whether a given guard will help your jaw, so treat marketing that leans on the letters FDA with some caution.
What Happens at the Dental Visit
A first visit is mostly history and hands: the dentist asks how the pain started, then feels your jaw muscles and joints.
One question comes up at nearly every visit, which is whether you need something to wear in your mouth and which kind. Three options exist, plus the option of wearing nothing at all. Side by side, they compare like this.
- Drugstore boil-and-bite night guard. Made by - you, at home, from a kit. Typical use - overnight, mainly to protect teeth from grinding wear. Cost - usually under $50 [5].
- Short-term splint, also called a temporary anterior bite plane. Made by - your dentist, chairside in one visit. Typical use - a few weeks on a written schedule while a strain settles. Cost - no dental lab fee, because nothing is sent out [2].
- Custom oral appliance, often a stabilization appliance. Made by - a dental lab, from impressions or a scan. Typical use - longer-term wear, usually at night. Cost - the highest of the three, plus fitting visits [7].
- No appliance at all. Made by - not applicable. Typical use - soft foods, heat or cold, and rest from clenching on their own. Cost - none, and this is where many people start [6].
The Exam
Expect questions about timing, triggers, sleep, stress, headaches, ear symptoms, and any clicking or locking [1]. Then comes the hands-on part. The dentist measures how wide you can open, presses on the chewing muscles to map tender spots, listens at the joints, checks how the teeth meet, and looks for grinding clues such as worn edges or a scalloped tongue border.
Some visits include imaging. A panoramic x-ray, billed as code D0330, shows the upper jaw, lower jaw, and both joints in one flat image, which helps rule out a tooth or bone problem that imitates a strained jaw [1]. Advanced imaging such as a cone beam CT, code D0367, is not routine this early and is usually saved for cases that do not follow the expected path [6].
The Short-Term Splint
If the exam points to a jaw sprain or strain, a dentist may fit a short-term splint. The general name for the device is a temporary anterior bite plane. It holds the front teeth slightly apart so the back teeth cannot meet, which makes hard clenching difficult and lowers how hard the closing muscles are able to fire [2]. QuickSplint is one commercial version, made chairside in a single visit rather than sent to a dental lab [2]. Other offices use a different chairside device for the same job, and the mechanism matters more than the brand on the box.
The comparison clinicians use is an Ace bandage versus a hard cast. A temporary anterior bite plane supports a strained jaw for a few weeks while it settles, and a custom oral appliance is the long-term device built from impressions or a scan in a dental lab [2]. Wearing schedules differ. Some patients wear it at night, some for short daytime stretches during a flare. Follow the schedule your dentist writes down, because a temporary anterior bite plane is not designed for open-ended use, and a partial-coverage appliance worn past its schedule can let the uncovered teeth drift [2].
It is fair to ask what the research shows. A 2010 systematic review in the Journal of Orofacial Pain examined randomized trials of intraoral appliances for temporomandibular disorders [7]. Its meta-analysis pooled seven randomized trials covering 385 patients that compared a hard stabilization appliance against a non-occluding appliance, and found an odds ratio of about 2.45 favoring the stabilization appliance [7]. The authors concluded that a properly adjusted hard stabilization appliance has good evidence of modest benefit for this kind of pain [7]. Read that carefully: the strongest evidence sits with the lab-made stabilization appliance, and the short-term chairside version has far less published study behind it. That is a reason to ask your dentist why they are choosing one over the other, and what the plan is if the splint does not help.
The Follow-Up
Plan on a check-in. Most care plans set a follow-up at two to four weeks to see whether pain, opening width, and tenderness have moved in the right direction [6]. Partial improvement by then is common and still counts as progress. If nothing has budged, that visit is where the plan changes: different exercises, a referral to physical therapy [8], a referral to another clinician, or a deeper workup.
Most jaw pain does not turn into a long-running problem, but some does, and pain that keeps returning is handled differently from a one-time strain [6]. If your pain settles and then comes back, or is still with you months later, say that plainly at the follow-up rather than starting the same two-week plan over again.
What Drives the Cost
Cost depends on how far the workup goes, from a single exam to imaging, a splint, physical therapy, and follow-up visits.
Costs vary by location, provider, and case complexity, but the codes make them checkable. Ask your office to write the billing codes on your treatment plan, then look up what each one runs near you with the free FAIR Health dental cost lookup [11]. The ranges below come from published 2025 and 2026 dental fee data and are cash prices, meaning what someone pays without insurance.
- Problem-focused exam. Code - D0140, a limited oral evaluation. Cash price - about $45 to $120, with discounted and rural fees near the bottom of that range and urban private-practice fees near the top [11].
- Panoramic x-ray. Code - D0330. Cash price - roughly $100 to $345, with many practices landing near $200 [11].
- Cone beam CT. Code - D0367, ordered only when 3D detail is needed. Cash price - roughly $200 to $880, with a national average near $466 [11].
- Appliance. Code - ask which occlusal guard code your office uses. Cash price - lowest for a chairside short-term splint, since there is no lab fee [2].
Insurance and Billing
A splint made chairside during the appointment carries no dental lab fee, since nothing is sent out [2]. A lab-made custom oral appliance costs more, commonly several hundred to a few thousand dollars, because it involves impressions or a scan, lab fabrication, and one or more fitting appointments.
Insurance is the messy part. Dental plans differ widely on whether they cover appliances for TMD, and some exclude them by name. Medical plans sometimes cover evaluation, imaging, and physical therapy for temporomandibular disorders. Jaw sprain and strain also has its own medical diagnosis code, S03.4, which is why some offices bill the medical plan rather than the dental plan [3]. Ask two questions before treatment starts: what codes will be used, and will this be submitted to dental or to medical.
Request a written treatment plan with codes and fees, then call your plan yourself. It is also fair to ask what happens if the pain resolves on its own, so you are not committed to a long-term appliance during week one.
When to Seek Help, and From Whom
Some jaw pain cannot wait. A jaw that locks, swelling with fever, or new numbness needs same-day care.
Get seen the same day, or go to an emergency room, for any of the following:
- A jaw locked open or locked closed, or a sudden drop in how wide you can open [10].
- Facial swelling, especially with fever, a bad taste, or swelling spreading toward the eye or down the neck. Spreading swelling goes to an emergency room.
- Jaw pain after a blow to the face, or a tooth knocked out. Facial trauma and an avulsed tooth go to an emergency room or an oral and maxillofacial surgeon immediately [5].
- New numbness or tingling in the lip, chin, or tongue.
- Jaw pain with chest pressure, shortness of breath, sweating, or arm pain. Call 911. Heart problems can present as jaw pain.
- A new, severe headache at the temple in an adult over sixty, with scalp tenderness or vision changes.
The Two-Week Mark
Short of those red flags, timing is your guide. Pain that is clearly improving by two to four weeks usually keeps improving on the same conservative care [6]. Pain that is unchanged, worse, or waking you at night at that point is the moment to have a dentist take a look [1]. The same is true for pain that keeps returning after it settles, or a jaw that has started locking.
Three Levels of Care
It helps to think in three levels of care. Your general dentist is the first stop and rules out the problems that imitate a strained jaw: a cracked tooth, an infection, a failing filling, an erupting wisdom tooth. Many general dentists manage a straightforward jaw sprain or strain themselves. Your general dentist makes the call on when a case needs another set of hands.
The second level is a general dentist with a TMD focus, meaning a general dentist who has completed continuing education in jaw and facial pain and treats these cases regularly. The focus belongs to the person, not to a category, so it is reasonable to ask what the training was and where it was done.
The third level is an orofacial pain specialist. Orofacial pain is an ADA-recognized dental specialty, and its residency programs are built around jaw pain, facial nerve pain, headache, and sleep-related jaw problems [1]. A general dentist and an orofacial pain specialist can both treat a jaw sprain or strain, and what separates them is training pathway and case mix rather than skill. Orofacial pain practices see a higher volume of long-running and complex cases, which shapes the workup: more time on history, closer attention to nerve and headache patterns, and routine coordination with physicians and physical therapists [8]. You can read more about the field on the orofacial-pain page.
Finding the Right Provider
If your jaw pain has run past two to four weeks, the next step is an exam. Start with your general dentist, who can treat the common causes and refer onward when the case calls for it. For pain that has lasted months, comes with headaches or nerve symptoms, or has not answered to home care, browse the orofacial-pain page to see providers near you, along with their training and clinical focus, before you pick up the phone.
