What is a Jaw?

The jaw includes the joints and muscles that help connect the mount with the base of the skull. These joints and muscles help us chew, swallow, talk as well as a yawn.

In this condition, the ophthalmic nerve, maxillary nerve and the mandibular nerve are affected. If you suffer from episodes of intense, stabbing, unexplainable pain for a few seconds, minutes or hours, then it may be trigeminal neuralgia. The treatment in this case is the use of medical drugs like anticonvulsant carbamazepine, antidepressant like amitriptyline, duloxetine in case of neurotic pain and opiates like morphine or oxycodone to manage pain. When medical therapy is not enough, the patient is advised surgery.

Many people suffer from jaw arthritis. This is another painful condition that occurs after years of wear and tear of the jaw joint. This causes problems with eating food, swallowing, etc. Muscle relaxants, pain relievers, etc. help in alleviating the painful symptoms.


Sinus is another condition that can lead to jaw pain. When the maxillary sinuses are infected, it can lead to jaw pain on the right side. One may also complain of heaviness of the face, congestion, etc. Decongestants, over the counter cold drugs, saline sprays may help in clearing the sinuses and reducing the jaw pain.

Dental Ailments

Teeth are a part of the jaw. Thus, any problem affecting the teeth can lead to pain in the jaw. Severe cavity, tooth infection, tooth fracture, periodontal disease, etc. can lead to pain in the jaw.  You may need to consult a dentist for further treatment. He may recommend anti-inflammatory drugs, antibiotics, root canal, tooth extraction or periodontal treatment that will help in curing jaw pain.

Jaw Fracture

One of the most severe facial injuries is jaw fracture. It will lead to severe pain, inability to move the jaw leading to problems chewing, talking, etc. The doctors will consider treatment based on the type of jaw fracture and involvement of the airway.

Diagnosis of jaw pain

The doctor will conduct a physical examination. He will try to observe the range of motion of the jaw. The doctor will also feel the jaw and listen to sounds by opening and closing the mouth. He may press on different areas of the teeth to see if one suffers from pain or discomfort in other areas of the face.

In case of any doubt, he may ask for an X-ray. If the X-ray is inconclusive or requires further clarification, a CT scan may be carried out for detailed images of the jaw bones.

Treatment of jaw pain

Treatment for jaw pain involves the application of hot or cold packs. One should eat soft foods such as yogurt, boiled and mashed vegetables, fruits, soup, etc. Avoid hard and chewy foods. One can wear night splints to avoid grinding teeth at night.

The doctor may advice muscle relaxants, sedatives, tricyclic antidepressants, pain relievers to alleviate the jaw pain. If the medical treatment does not show any improvement, the doctor may suggest Botox injections into the jaw. When also does not help relieve the pain, surgical treatments may be the only option left.

Jaw pain is mostly due to dental problems. Once the dental problem is treated, jaw pain subsides on its own. Use of mouth guards and splints helps prevent the grinding of teeth at night. If you suffer from constant jaw pain on left or right side, speak to your doctor immediately. It may be a sign of something serious that requires medical treatment.
