The pain is more usually unilateral (located on one side) rather than bilateral. [20] It is rarely severe. [25] Limited range of mandibular movement, [2] which may cause difficulty eating or even talking. There may be locking of the jaw, or stiffness in the jaw muscles and the joints, especially present upon waking. [19]
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

Oromandibular dystonia is characterized by involuntary spasms of the tongue, jaw, and mouth muscles that result in bruxism, or grinding of the teeth, and jaw closure. These conditions frequently lead to secondary dental wear as well as temporomandibular joint syndrome. In addition, problems with chewing, speaking, and swallowing may result from ...
If your clenching is particularly severe, you might be prescribed a muscle relaxant that reduces muscle spasms in your face and jaw. “Just as you would expect, it relaxes the muscles of the jaw ...
Eventually, subperiosteal bone formation may give a firm swelling. Trismus (difficulty opening the mouth), which may be present in some cases and is caused by edema in the muscles. Dysphagia (difficulty swallowing), which may be present in some cases and is caused by edema in the muscles. Cervical lymphadenitis (swelling of the lymph nodes in ...
It is a temporary condition that usually lasts no more than two weeks. Dental trismus is caused by an injury to the masticatory muscles, such as opening the jaw for an extended period of time or having a needle pass through a muscle. Typical dental anesthesia for the lower jaw involves inserting a needle into or through a muscle.
The four classical muscles of mastication elevate the mandible (closing the jaw) and move it forward/backward and laterally, facilitating biting and chewing. Other muscles are responsible for opening the jaw, namely the geniohyoid , mylohyoid , and digastric muscles (the lateral pterygoid may play a role).
Temporomandibular disorder (TMD, also termed "temporomandibular joint pain-dysfunction syndrome") is pain and dysfunction of the TMJ and the muscles of mastication (the muscles that move the jaw). TMD does not fit neatly into any one etiologic category since the pathophysiology is poorly understood and it represents a range of distinct ...
