Most jaw pain responds well to a combination of home treatments: cold or warm compresses, gentle exercises, over-the-counter anti-inflammatory medication, and avoiding foods that force your jaw to work hard. For many people, these steps resolve the pain within a few days to a few weeks. When they don’t, professional options like custom splints or targeted injections can help. Here’s how to work through each approach.
Why Your Jaw Hurts
The temporomandibular joint (TMJ) is the hinge connecting your lower jaw to your skull, and it’s one of the most frequently used joints in your body. When something goes wrong with this joint or the muscles around it, the resulting condition is called a temporomandibular disorder, or TMD. Despite how common TMD is, the exact cause often isn’t clear. For many people, symptoms seem to start without an obvious reason.
Current evidence points to a combination of factors: genetics, psychological stress, life stressors, and individual differences in pain perception all play a role in whether TMD develops and whether it becomes long-lasting. Direct injury to the jaw is another trigger. One persistent myth is that a bad bite or braces cause TMD, but research does not support that belief. Understanding this matters because it means the most effective relief strategies target pain, inflammation, and muscle tension rather than trying to “fix” your bite.
Cold and Heat for Quick Relief
Cold therapy is your best first move when jaw pain flares up, especially if there’s swelling. Cold numbs the area and reduces inflammation. Wrap ice in a damp towel or use a sealed plastic bag filled with ice and a little water, then apply it to the painful side of your jaw. Never place ice directly on skin. Keep it on for 15 to 20 minutes, then take a break.
After the first 48 hours, you can switch to warmth. A warm, damp towel placed along the jaw relaxes tight muscles and increases blood flow to the area. Some people alternate between cold and warm compresses and find that more effective than either alone. If the pain just started and you’re not sure whether there’s inflammation, start with cold.
Exercises That Reduce Tension
Gentle jaw exercises can improve mobility and ease muscle tightness, but they should never increase your pain. If any movement hurts, back off.
Resisted Opening
Place your tongue on the roof of your mouth, then rest your chin on your fist. Slowly open your jaw while your fist provides gentle resistance. Open only as far as you can without your tongue leaving the roof of your mouth. Watch in a mirror to make sure your lower jaw doesn’t drift forward or to one side. This builds stability in the joint without straining it.
Side-to-Side Resistance
Keep your tongue in its resting position with your teeth slightly apart. Place one hand against the left side of your jaw and push gently, but don’t let your jaw actually move. Hold for five seconds. Repeat on the right side, then place your hand under your chin and push upward, again holding for five seconds without movement. These isometric holds strengthen the muscles around the joint without requiring any range of motion that could irritate it.
Aim for two to three sessions per day. Many people notice improvement within a week or two of consistent practice.
Over-the-Counter Pain Relief
Ibuprofen is particularly useful for jaw pain because it reduces both pain and inflammation. For mild pain, 200 to 400 mg every four to six hours as needed is a standard approach. For moderate pain, the American Dental Association’s guidelines suggest 400 to 600 mg at fixed intervals every six hours for the first 24 hours, then stepping down to 400 mg as needed. Combining ibuprofen with acetaminophen (500 mg) can provide stronger relief for more stubborn pain, since the two drugs work through different pathways and complement each other well.
Naproxen is another over-the-counter option that lasts longer per dose, which some people prefer for overnight relief. Whichever you choose, use the lowest effective dose for the shortest time needed.
What to Eat During a Flare
Switching to softer foods during a jaw pain episode makes a noticeable difference. Avoid anything chewy, tough, crunchy, or large enough to require you to open your jaw wide. That means skipping beef jerky, bagels, raw carrots, steak, caramel, corn nuts, and whole apples.
You don’t have to live on soup. Good soft-food options include:
- Protein: eggs, tofu, fish, chicken, and legumes
- Fruits: bananas, applesauce, ripe melons, soft pears
- Vegetables: cooked carrots, squash, peas, and asparagus (peel the skins if they’re tough)
- Grains: oatmeal, pasta, couscous, polenta, mashed potatoes
- Dairy: yogurt, cottage cheese, pudding, kefir
Cut food into small pieces so you can chew without opening wide, and try to chew evenly on both sides.
Sleep Position Matters
Your sleeping posture can either ease or worsen jaw pain overnight. Sleeping on your back is the best position for TMD because it keeps your head, neck, and spine aligned and avoids putting direct pressure on the joint. A contoured or memory foam pillow helps prevent your head from tilting forward or to the side, which can pull the jaw out of alignment.
Side sleeping is a common culprit, especially if you tuck your hand under your jaw. That forces the joint into an unnatural position and creates sustained pressure for hours. Stomach sleeping is the worst option: it requires you to turn your head to one side, twisting your neck and pressing your jaw into the pillow. If you’re a stomach sleeper dealing with persistent jaw pain, retraining your sleep position is one of the highest-impact changes you can make.
Night Guards and Dental Splints
If you grind or clench your teeth at night, a dental splint (often called a night guard) can significantly reduce jaw pain by protecting the joint from hours of sustained pressure. There are two main types. Stabilization splints cover the full arch of your teeth and are typically recommended for people with muscle-related pain, clenching, or grinding. Anterior repositioning splints shift the lower jaw slightly forward to improve the relationship between the jaw bone and the disc inside the joint, and they’re especially useful for disc-related problems like clicking or catching.
Both types produce significant improvements in TMD symptoms, and studies comparing them head to head have found no major difference in overall effectiveness. The right choice depends on what’s driving your specific pain. Custom-fitted splints from a dentist outperform generic drugstore versions because they’re molded to your bite and adjusted over time.
Professional Treatments for Persistent Pain
When home strategies aren’t enough, targeted injections into the masseter (the large chewing muscle on each side of your jaw) can relax the muscle and break the cycle of tension and pain. A typical treatment uses 20 to 30 units per side, with results lasting four to six months before a repeat session is needed. This approach is especially helpful for people who clench heavily or have visibly enlarged jaw muscles from chronic grinding.
Physical therapy is another option. A therapist can perform manual techniques on the joint and surrounding muscles, guide you through progressive exercises, and address posture issues in your neck and shoulders that may be contributing to jaw strain.
Jaw Pain That Isn’t About Your Jaw
In rare cases, jaw pain is referred pain from the heart. The difference is distinct. Musculoskeletal jaw pain is localized: you can point to exactly where it hurts, and it flares up when you yawn, chew, or open wide. Cardiac-related jaw pain is diffuse, hard to pinpoint, and may feel more like a pulsating sensation than a deep ache. It gets worse with physical exertion like climbing stairs rather than jaw movement, and it comes with other warning signs: sweating, flushing, dizziness, or confusion.
The context matters too. Someone with risk factors like high blood pressure, diabetes, smoking, or a family history of heart disease should take unexplained jaw pain more seriously, especially if it comes on suddenly during exertion and doesn’t fit the typical pattern of joint or muscle pain.
