Have you ever noticed your jaw making a clicking sound on one side when you eat, talk, or yawn? While it might seem harmless, a clicking jaw can sometimes be a sign of a problem with your temporomandibular joint (TMJ). TMJ disorders, also called TMD, affect up to 70% of people at some point in their lives, though only a few seek treatment.
Common Causes of One-Sided Jaw Clicking
- Teeth Grinding or Clenching (Bruxism)
Many people grind or clench their teeth during sleep without realizing it. A dentist on Mercer Island can help diagnose this issue and recommend treatments like night guards or relaxation techniques. This can cause soreness and stiffness in the jaw muscles and may lead to clicking on one or both sides. Some also grind their teeth during the day, especially when stressed.
Stress and Anxiety
Stress can cause you to tighten your jaw muscles without noticing. This habit increases pressure on the TMJ, leading to pain, tension, and clicking. Managing stress can help reduce these symptoms.
- Arthritis
Arthritis can affect the jaw joint just like any other joint in the body. Osteoarthritis wears down cartilage with age, while rheumatoid arthritis and psoriatic arthritis can cause inflammation, stiffness, and pain in the TMJ. These conditions may also lead to clicking or popping sounds during movement.
- Disc Displacement
Inside your jaw joint is a small disc that helps cushion movement. Sometimes this disc moves out of place, known as disc displacement. When the disc slips but moves back into position, you may hear a clicking sound. If it stays out of place, you might find it hard to open your mouth fully.
- Malocclusion (Bad Bite)
When your teeth don’t fit together properly, it can place extra strain on one side of your jaw. Over time, this uneven pressure can cause pain, stiffness, and clicking sounds.
- Jaw Injury
An injury to your jaw joint, such as a hit to the face, can cause swelling, stiffness, and clicking. In severe cases, medical treatment or surgery may be needed.
Diagnosing Jaw Clicking
To find out what’s causing the clicking, a dentist or doctor will examine your jaw and ask about your symptoms. They might listen for sounds, check how your jaw moves, and gently press around the joint.
If needed, they may suggest tests such as:
- X-rays – to check your teeth and jaw joint
- MRI scans – to view the soft tissues and joint disc
- CT scans – to look at the bones of your jaw
Treatment Options
- Home care: Apply hot or cold packs, take mild pain relievers, and try to reduce stress.
- Jaw exercises and physiotherapy: Gentle stretches and strengthening movements can improve mobility and reduce clicking.
- Oral splints or mouthguards: These help keep your bite balanced and prevent teeth grinding.
- Medications: Anti-inflammatory or muscle relaxant medicines can ease discomfort.
Surgery: For severe cases or injuries, procedures like TMJ arthroscopy or joint replacement may be needed.
