Lockjaw is a general term for stiffness and pain around your jaw muscles. In most cases, this is from a problem in your temporomandibular joint (TMJ), your main jaw joint. This sounds scary, but it’s a common problem that you can manage yourself. Remember, however, that lockjaw is also a symptom of tetanus, a dangerous disease. This is much rarer than TMJ, but if you have lockjaw along with a fever, chills, sweats, and other muscle spasms, then seek emergency medical help right away. [1] If pain and stiffness are your only symptoms, then your lockjaw is probably a simple TMJ flareup. In this case, you can try some self-help tips at home to make yourself feel better.

Relieving Pain and Stiffness

If a TMJ flareup is causing lockjaw, then you’re probably feeling pretty lousy. Common symptoms are pain and stiffness in your jaw, along with headaches and fatigue. Dentists usually recommend taking NSAID pain relievers until the flareup passes, but there are some natural steps you can take as well. [2] Try these tips to reduce your pain and discomfort during a flareup.

  1. This is helpful to relieve the pain and stiffness during a lockjaw flareup.
    • A massage could help if your jaw feels tight or you can’t open your mouth much.
  2. If your jaw hurts, then a cold treatment can help reduce pain. [3] Hold an ice or cold pack to the side of your face near the jaw joint for 10 minutes at a time. Repeat this a few times throughout the day if you have to.

  3. Try holding a moist heating pad against your face for 5-10 minutes. This could reduce your pain and increase flexibility in your jaw.
    • There isn’t a strict rule on whether you have to use heat or cold to treat your jaw. In general, use the one that helps you the most. [4]
  4. If your jaw is completely locked open or shut, this could be a serious medical situation. Don’t panic, but take action fast. Call your doctor right away or go to the emergency room to have the problem fixed. [5]
    • Doctors may need to manipulate your jaw to unlock it. This sounds alarming, but they should numb the area so you don’t feel pain during the procedure.
    • If you also have a fever, sweats, high blood pressure, and a rapid heart rate when your jaw locks, then these are all symptoms of tetanus. Seek emergency medical help right away. [6]

Relaxing Your Jaw

A case of lockjaw puts a lot of stress on your jaw muscles and joints. Relaxing those muscles is a good way to treat the flareup and prevent future problems with your jaw. This takes some work during your daily life, so try these tips to avoid stressing your jaw during a TMJ flareup.

  1. Hard or crunchy foods like pretzels or hard fruits take more work to eat and might make your pain worse. Stick with softer foods like yogurt, pudding, rice, eggs, fish, or mashed potatoes. This should prevent the inflammation from getting worse.
    • You can also steam or bake fruits and vegetables so they’re easier for you to eat.
  2. It's tough to control yourself during a delicious meal, but large bites could over-stress your jaw muscles. Either take small bites or cut your food into tiny pieces to avoid making your pain worse. [7]
  3. It's easy to get too excited, but relaxing your jaw is important during a TMJ flareup. Avoid opening your jaw wider than you’re comfortable with, or you might make the inflammation worse. [8]
  4. Your teeth shouldn’t press together unless you’re chewing. Otherwise, keep your teeth slightly apart. This keeps pressure off your jaw muscles. [9]
    • You might be pressing your teeth together without realizing it. If you catch yourself doing that, remind yourself to keep your teeth apart.
    • Try resting your tongue on top of your bottom row of teeth to force yourself to keep your teeth apart.
  5. This overworks your jaws and could make your pain worse. It's best to avoid gum altogether. [10]
  6. You might not even realize you’re doing this, but it’s a major trigger for jaw pain. If you regularly tap or grind your teeth together, do your best to break that habit.
    • If you can’t stop grinding your teeth during the day, you could wear a bite guard to cushion your jaw. Talk to your dentist about having one of these made for you.
  7. This might not seem related, but stress could actually trigger TMJ pain. Try taking steps to reduce stress in your daily life to prevent further discomfort. [11]
    • Some relaxation activities like meditation or yoga might help reduce your stress. Try making time for one of these each day to help yourself relax.
    • Doing things you enjoy is also good to keep your stress levels low.
  8. Nighttime grinding is a common problem, especially if you’re stressed. This is tough to control since you’re not awake, so if you have a grinding problem, you can use a plastic nightguard over your teeth to protect your jaw. [12]
    • Your dentist can usually tell if you have a grinding problem by the scratches on your teeth. They’ll probably tell you if they see signs of grinding and suggest a nightguard.
  9. Some stretching and strengthening exercises could relieve the pain and inflammation in your jaw. Ask your dentist for some recommended exercises that might help you, then do them exactly as your dentist instructs you to. [13]
    • Your dentist might also recommend physical therapy or a therapeutic massage to relieve your pain. [14]

Alternative Treatments for Pain

There are a few alternative remedies that could help with TMJ as well. These aren’t proven with research, but some people find them helpful. They’re also mostly harmless, so you can try them for yourself to see if they work for you.

  1. Acupuncturists can help relieve chronic pain like TMJ by accessing pressure points to release tension. This isn’t guaranteed to work, but you can try it out for yourself. [15]
    • Always visit a licensed and experienced acupuncturist so you know you’re getting a professional treatment.
  2. Glucosamine is a popular treatment for arthritis because it can help support joint health. This might help with your TMJ as well. Try taking a daily supplement to see if this helps you. [16]
    • A common glucosamine dose to treat arthritis is 1.5 g per day, but follow the dosing instructions on the brand that you use. [17]
    • Glucosamine could interfere with blood thinners and a few other medications, so ask your doctor before taking it.
  3. There is no clear link between calcium, magnesium, and TMJ, but some people with TMJ issues have deficiencies in these nutrients. If you aren’t getting enough of each in your regular diet, then try taking some dietary supplements to boost the amount in your body. [18]
  4. Vitamin C does help support the cartilage in your body, which could be beneficial for treating TMJ. There aren’t any studies proving this, but boosting your vitamin C intake might help you. [19]
    • Good sources of vitamin C include citrus fruits, bell peppers, leafy green vegetables, tomatoes, berries, and melon. [20]

Medical Takeaways

Lockjaw might be alarming, but most cases aren't serious. It's usually caused by a TMJ flareup, meaning that the joint in your jaw is inflamed. This sounds scary, but many people experience it and you can manage it from home. Remember that lockjaw could, in rare cases, be a symptom of tetanus, so seek emergency medical help if you also have a fever. If not, then managing the pain and inflammation at home should help a lot. If you still don’t see any improvement, then talk to your dentist for more options.
