Jaw pain on only one side can be uncomfortable and concerning, especially when it affects eating, speaking, or sleeping. While occasional soreness may be temporary, persistent one-sided jaw pain often points to an underlying issue that deserves attention. Understanding the most common causes can help you determine when to seek professional care.
Teeth Grinding or Clenching
One of the most common reasons for one-sided jaw pain is teeth grinding or clenching, also known as bruxism. Many people grind their teeth at night without realizing it, placing excessive pressure on the jaw muscles and joints. If you tend to favor one side while clenching, pain may develop only on that side. Morning jaw soreness, headaches, or worn teeth are common signs.
Temporomandibular Joint (TMJ) Disorders
The temporomandibular joints connect your jaw to your skull and allow smooth movement when you chew or speak. TMJ disorders can cause pain, clicking, popping, or limited movement—often on just one side. Poor posture, stress, arthritis, or jaw injury can contribute to TMJ problems, making daily activities uncomfortable.
Dental Problems on One Side
Issues such as a cavity, cracked tooth, abscess, or impacted wisdom tooth can cause localized jaw pain. Because these problems typically affect one tooth or area, discomfort may be felt only on one side of the jaw. Infections can also cause swelling and tenderness that radiate into the jawbone.
Sinus Infections or Congestion
The upper jaw sits close to the sinuses, and sinus infections or inflammation can create pressure that feels like jaw pain. This discomfort often affects one side, especially if only one sinus cavity is involved. Sinus-related jaw pain may worsen when bending over or accompanied by congestion and facial pressure.
Muscle Strain or Injury
Chewing gum excessively, favoring one side when chewing, or sustaining a facial injury can strain jaw muscles. Even minor trauma or overuse can lead to soreness on one side. Stress and tension can also cause you to unconsciously tighten jaw muscles, resulting in localized pain.
When to See a Dentist or Doctor
Occasional jaw pain may resolve on its own, but ongoing or worsening discomfort should be evaluated. Seek professional care if pain lasts more than a few days, interferes with daily activities, is accompanied by swelling, fever, or difficulty opening your mouth, or is linked to tooth pain.
Jaw pain on only one side can stem from dental issues, muscle strain, TMJ disorders, or sinus problems. Identifying the cause is essential for proper treatment and long-term relief. A dental evaluation can help pinpoint the source of discomfort and guide you toward effective solutions so you can get back to smiling, chewing, and living comfortably.
