Jaw discomfort is a common issue, but when you feel pain on only one side, it can be particularly concerning. You might wonder whether this sensation is a minor annoyance or a sign of something serious, such as a dental emergency. In this blog post, you will learn about potential causes of one-sided jaw pain and steps that may help you find relief.

Could Jaw Pain Signal a Heart Attack?

Although most cases of jaw pain are not emergencies, it is important to recognize when your discomfort might be a warning sign of a heart attack. If your jaw pain appears along with other symptoms such as chest tension or pressure, severe fatigue, shortness of breath, or unexpected sweating, you should contact emergency services immediately. Quick action can be lifesaving!

Temporomandibular Joint Disorder (TMD)

The temporomandibular joints connect your jaw to your skull. These joints can become inflamed or damaged, leading to a condition known as temporomandibular joint disorder (TMD). TMD may cause pain on one or both sides of your jaw, and it often comes with other symptoms, such as clicking sounds when you open or close your mouth.

If you suspect TMD, you should schedule a dental evaluation. A qualified professional will strive to pinpoint the cause of your pain and suggest a treatment that will reduce or eliminate your symptoms.

Dental Abscess

A dental abscess is a pocket of pus that forms due to a severe tooth infection. This condition can cause intense, localized jaw pain, often on one side. You might also notice:

  • Facial swelling
  • Fever
  • An unpleasant taste in your mouth

A dental abscess is a true emergency! Prompt care is crucial to prevent the infection from spreading. Treatment may involve draining the abscess, performing root canal therapy, or, in some cases, extracting the affected tooth.

Sinusitis

Sinusitis occurs when the sinuses become inflamed due to allergies or a bacterial infection. This inflammation can lead to pain above your jaw, sometimes affecting only one side. If you have symptoms that persist for more than a week, it is a good idea to visit your primary care doctor. Options such as antibiotics or nasal sprays may provide relief.

Other Possible Reasons for One-Sided Jaw Pain

While less common, there are several other conditions that can cause pain on just one side of your jaw:

  • Trigeminal neuralgia: Malfunction or compression of the trigeminal nerve can result in sudden, severe facial pain, often on one side. Treatment options include medications, surgical procedures, or nerve block therapy.
  • Osteomyelitis: This rare bone infection may develop after surgery, bringing symptoms such as jaw pain, fever, and swelling. Immediate medical attention is necessary to prevent further complications.
  • Tumors and cysts: Benign or cancerous growths can cause discomfort in your jaw. Surgical removal is often required to address the problem and relieve pain.

Listen to Your Body and Seek Help

Jaw pain on one side could be a sign of a serious health concern or a less urgent issue. In any case, you should pay attention to your symptoms and seek professional care when necessary. By addressing your discomfort promptly, you can protect your well-being and get on the path to lasting pain relief.
