It connects the lower jawbone (the mandible) to the skull (the temporal bone).<\/p>\n<p>Like all joints, the TMJ is made up of cartilage on the articular surfaces, ligaments, muscles, tendons, and a fluid that helps lubricate it. It also contains a small articular disc (meniscus) that moves with the jaw. This disc helps stabilize the joint during movement and properly distributes pressure when chewing.<\/p>\n<h2>What causes jaw pain?<\/h2>\n<p>Jaw pain can be caused <strong>by a traumatic injury<\/strong>, such as:<\/p>\n<ul>\n<li>a blow to the jaw;<\/li>\n<li>a fall on the chin;<\/li>\n<li>a sudden opening\/closing of the jaw in a car accident (also known as <em>jawlash<\/em>).<\/li>\n<\/ul>\n<p>Such incidents can lead to inflammation and various jaw injuries such as a <strong>fracture<\/strong>, <strong>dislocation<\/strong>, <strong>sprain<\/strong>, or <strong>muscle spasm<\/strong>.<\/p>\n<p>Jaw pain can also <strong>develop over time<\/strong> due to:<\/p>\n<ul>\n<li>poor lifestyle habits (e.g., constantly chewing gum, nail-biting, frequently biting lips, or regularly resting the chin in your hand);<\/li>\n<li>bruxism (clenching or grinding teeth);<\/li>\n<li>stress;<\/li>\n<li>poor posture maintained repetitively or for prolonged periods;<\/li>\n<li>poor dental occlusion, meaning the way your upper and lower teeth come together;<\/li>\n<li>dental procedures that require keeping the mouth wide open for several minutes;<\/li>\n<li>etc.<\/li>\n<\/ul>\n<p>A combination of these factors can lead to muscle tension and contribute to jaw or <a href=\"https:\/\/physioextra.ca\/en\/condition\/neck-pain\/\">neck pain<\/a>, <a href=\"https:\/\/physioextra.ca\/en\/condition\/headaches\/\">headaches<\/a>, and sometimes ear-related symptoms such as pain, a feeling of fullness in the ear, or tinnitus (like ringing or buzzing in the ears).<\/p>\n<p><a class=\"btn-calendrier-contenu condition\" href=\"https:\/\/reservation.physioextra.ca\/en\/\" target=\"_blank\" rel=\"noopener\"><span class=\"nul\">Book an appointment<\/span><\/a><\/p>\n","protected":false},"featured_media":10397,"template":"","class_list":["post-2393","condition","type-condition","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.3 (Yoast SEO v27.3) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Sore Jaw: Symptoms, Causes and Treatments | PhysioExtra<\/title>\n<meta name=\"description\" content=\"Muscle stiffness, cracking or tension in the jaw (temporomandibular joint) can cause pain or headaches.
