A clicking or popping sound from the jaw when chewing is a common experience. While this sensation can sometimes be a minor annoyance that resolves on its own, it can also indicate an underlying issue with the jaw joint. Understanding the jaw’s mechanics and factors contributing to these sounds can help determine when to seek further evaluation.
Understanding the Jaw Joint
The temporomandibular joint, or TMJ, connects your jawbone to the skull. Each side of your face has one of these joints, functioning like a hinge to facilitate movement. These movements include opening and closing your mouth, moving your jaw side to side, and shifting it forward and back.
Within this joint lies an articular disc, a piece of cartilage that cushions the jaw joint and allows for smooth motion. When the jaw moves, this disc typically glides in and out of place along with the jawbone. Popping sounds can occur when this articular disc slides out of its normal position and then snaps back into place during jaw movement.
Common Causes of Popping
Jaw popping often stems from issues affecting the temporomandibular joints and surrounding muscles and ligaments. One frequent cause is temporomandibular joint dysfunction (TMD), where the cushioning disc shifts out of alignment.
Habitual actions like grinding your teeth (bruxism) or clenching your jaw can place excessive pressure on the TMJ, contributing to popping sounds. Frequently chewing gum or biting fingernails can also strain these joints. These repetitive stresses can lead to muscle tension and joint irritation.
Certain medical conditions can also lead to jaw popping. Forms of arthritis, such as osteoarthritis and rheumatoid arthritis, can damage cartilage within the jaw joint, causing clicking or grating noises. A misaligned bite (malocclusion), where the upper and lower teeth do not meet correctly, can also put undue stress on the TMJ, resulting in popping. Additionally, a direct injury or trauma to the jaw, or conditions like myofascial pain syndrome, can impact the jaw joint and lead to popping.
When Popping Signals a Problem
While an isolated jaw pop without other sensations is often considered benign, accompanying symptoms can signal a more significant issue, typically a temporomandibular disorder (TMD).
A person may experience pain or tenderness in the jaw, face, or around the ear. Other signs include stiffness in the jaw muscles, difficulty opening the mouth wide, or the jaw feeling as though it is locking in either an open or closed position. Headaches, earaches, or difficulty chewing can also accompany jaw popping when a TMD is present. If jaw popping occurs with any of these symptoms, it warrants evaluation by a healthcare provider to determine the cause and appropriate course of action.
Treatment and Self-Care Options
Managing jaw popping often begins with self-care strategies, particularly when symptoms are mild or intermittent. Eating softer foods can reduce strain on the jaw joint, and avoiding habits like chewing gum, biting fingernails, or clenching the jaw can help. Applying warm compresses or ice packs to the jaw can soothe muscle discomfort and reduce swelling. Practicing stress management techniques, such such as meditation or deep breathing, can alleviate jaw tension caused by stress-induced grinding or clenching.
When home remedies are not enough, professional treatments can provide further relief. A dentist may recommend a custom-made mouthguard or splint, which can help reposition the jaw and prevent teeth grinding during sleep. Physical therapy, including specific jaw exercises, can improve jaw function and reduce discomfort. Over-the-counter pain relievers or anti-inflammatory medications, such as NSAIDs, can manage pain and inflammation.
For issues related to a misaligned bite, restorative dentistry treatments like crowns, bridges, or braces may be suggested to correct tooth alignment. In some cases, other therapies like trigger point massage or transcutaneous electrical nerve stimulation (TENS) might be used to relax jaw muscles and relieve pain. Surgical intervention is generally considered a last resort for severe cases that do not respond to other treatments.
