What is on your mind?

Tingling and loss of feeling in your jaw can be concerning when you don’t know why it’s happening. There can be many causes of these symptoms, some serious and others less problematic. It’s important to learn what is causing these symptoms so you can seek effective treatment.

What Are The Causes of a Tight and Numb Jaw?

Tightness or numbness in any part of your body is commonly associated with the nerves that populate that area. The same goes for sensations of these types in your face and jaw.

Stroke or Trans Ischemic Attack (TIA)

Many people worry that when their jaw feels tight and numb, it can be an indicator of a stroke or TIA (also known as a “mini-stroke” or “warning stroke”). A stroke or TIA can indeed cause facial numbness, tightness or paralysis, including in your jaw area. A stroke or TIA is the result of a blood clot lodging in one of the smaller blood vessels in your brain, cutting off the blood supply to that portion of the brain. In the case of a stroke, symptoms don’t decrease and often worsen. Strokes are often also accompanied by a lack of coordination or loss of function on one side of the body, slurred speech, drooping of the face or loss of consciousness. TIAs are similar to strokes; however, the clot will dissolve and move, with symptoms often vanishing as quickly as they appeared. It’s important to seek immediate medical attention if you experience any of these symptoms.

Trigeminal Neuralgia

While it may have a complicated-sounding name, trigeminal neuralgia is simple in its cause. The trigeminal nerve serves to provide sensation to both sides of your face. It is the largest of the cranial nerves, providing feeling and controlling functions such as chewing and smiling on both sides of the face. It passes through several structures near the base of your skull; sometimes, it can become irritated or compressed when it is too close to a blood vessel. This compression typically results in excruciating bouts of pain in the face, but can also manifest as numbness or a feeling of tightness.


Sometimes, if a tumor (either benign or cancerous) is growing too close to one of your facial nerves, it can compress the nerve, disrupting its ability to send signals and register sensation. There are even tumors that can grow specifically on nerves or the nerve sheath (the outer layer that protects the highly sensitive portion inside). Some of these types of tumors include Schwannomas and neurofibromas, among others.

Bell’s Palsy

Another condition that people report making their jaw tight or numb is Bell’s palsy. Bell’s palsy usually occurs on one side of your face. It can cause numbness, a tight sensation and also drooping in addition to drooling. It is the result of a swollen facial nerve and is thought to mostly be associated with a post-viral infection. Because its symptoms are often similar to that of a stroke, it’s important to have it checked to rule out other possibilities.

Treatment options for tight and numb jaw

Depending on why your jaw feels tight and numb, the treatment options vary. Below are some of the most common treatments for the various conditions that can cause these symptoms.


The most critical step in proper stroke/TIA care is a quick diagnosis. This will allow the necessary medications to be administered, along with cardiac monitoring. The term “time is brain” sums up the need for immediate and appropriate treatment. Drugs such as blood thinners are used to help break down clots that are causing the blockage, while they also help prevent new ones from forming. Surgical intervention may also help; a procedure known as carotid endarterectomy is used to remove the plaques that result in the majority of stroke-causing clots.

Trigeminal Neuralgia

Medications are used with limited success to help control the symptoms of trigeminal neuralgia in some patients; however, they tend to wear out and become ineffective. The most successful, long-term treatment for trigeminal neuralgia is a less invasive surgical procedure known as microvascular decompression (MVD). This surgery involves the neurosurgeon using specialized instruments to access the point of the compression. A small surgical device made of Teflon is placed between the nerve and blood vessel, eliminating the pulsing that causes irritation and inflammation of the nerve.


Tumor treatment to eliminate the symptoms of a tight and numb jaw can vary widely, depending on the type of tumor, its location and whether or not it is benign or malignant (cancerous). Options including surgery, medications and radiation therapy, may be considered.

Bell’s Palsy

Because Bell’s palsy is considered a temporary condition, corticosteroid treatment is often recommended to help alleviate the inflammation and provide some relief. Antivirals can be used in some cases, but their use is somewhat controversial, a viral infection may not always cause Bell’s palsy.

Regardless of the reason your jaw feels numb and tight, the first step towards relief is receiving an accurate diagnosis. Whether you start with your general practitioner or choose to seek out the advice of a specialist, such as a neurosurgeon, be sure you can get the answers you need to your questions.
