Waking up with pain on one side of your jaw can be uncomfortable—and understandably concerning. Fortunately, one-sided jaw pain isn’t always a sign of something serious. It can happen for several reasons, including dental problems, muscle tension, or issues involving the temporomandibular joint (TMJ). Understanding some common causes can help you determine when it’s time to seek professional care.
TMJ Problems
Your temporomandibular joints connect your jawbone to your skull and allow you to open your mouth, chew, and speak. When one of these joints becomes irritated or inflamed, you may experience pain on just one side of your jaw.
Temporomandibular joint disorders, commonly called TMD, can cause jaw tenderness, clicking or popping, stiffness, headaches, and discomfort when chewing or opening your mouth. Clenching or grinding your teeth can also put additional stress on the jaw muscles and joints.
A Dental Infection
A tooth infection can sometimes cause pain that radiates into the jaw. You may notice throbbing or persistent pain around a specific tooth, along with sensitivity to hot or cold, swelling, or tenderness.
An untreated dental infection can spread to surrounding tissues, so it’s important not to ignore these symptoms. Prompt dental treatment can help address the underlying infection and prevent complications.
Tooth Decay or Damage
A cavity, cracked tooth, or damaged filling can also cause pain that seems to extend into the jaw. Depending on the problem, you might experience sensitivity while eating or drinking, discomfort when biting down, or a persistent ache.
Because dental pain can sometimes be difficult to pinpoint, an examination can help determine whether the discomfort is coming from a specific tooth or another part of the jaw.
Sinus Problems
Your sinuses are located near the upper jaw, so congestion or a sinus infection can sometimes cause pressure or aching in the upper teeth and jaw. Sinus-related discomfort may affect one or both sides and often occurs alongside other symptoms, such as facial pressure, nasal congestion, or a headache.
If your jaw pain appears alongside significant dental symptoms, however, it’s still a good idea to have a dentist rule out an oral health problem.
Injury or Muscle Strain
An injury to the face or jaw can cause localized pain and swelling. Even something as simple as excessive chewing or prolonged clenching can strain the muscles surrounding the jaw.
Resting your jaw, choosing softer foods temporarily, and avoiding activities that aggravate the discomfort may help mild muscle-related pain improve.
When Should You See an Emergency Dentist?
Not every instance of jaw pain requires emergency treatment, but certain symptoms deserve prompt attention. Seek urgent dental care if you have severe or worsening pain, significant swelling, fever, a dental injury, or signs of an infection.
Jaw pain accompanied by chest pain, shortness of breath, sweating, nausea, or pain spreading into the arm, shoulder, neck, or back can indicate a medical emergency rather than a dental problem. Seek immediate medical attention if these symptoms occur.
If your jaw pain persists or keeps returning, don’t simply try to live with it. Identifying the underlying cause can help you find appropriate treatment and prevent the problem from becoming more serious.
