Temporomandibular Disorders (TMD): A Complete Guide

When visiting the dentist you might have heard of the acronyms TMD and TMJ. But, you still might be wondering what is TMD in dentistry and what is TMJ dental? Put simply, Temporomandibular Disorders (TMD) are a group of conditions that affect the Temporomandibular Joint (TMJ) and the surrounding structures.

According to research, the prevalence of TMDs can vary, with some studies reporting an average prevalence of 31% of adults and 11% of children. What is temporomandibular joint? The TMJ is a synovial joint that connects the lower jaw to the skull. The TMJ allows for up-and-down, side-to-side, and forward-and-backward movements of the jaw which is necessary for chewing, speaking, and making facial expressions. In this article we dive into important details you need to know about TMD vs TMJ.

Understanding the Causes of TMD

There are several potential causes of TMD. A combination of factors may play a role, which can make identifying a specific cause challenging. Common causes of TMD include injury or trauma to the TMJ, genetic predisposition, teeth grinding and clenching, stress and anxiety, medical conditions (i.e. arthritis, neuralgia, lupus), and misaligned bite and teeth. In many cases, the exact cause of TMD is unknown.

Recognizing the Symptoms of TMD

There are several common TMD symptoms to recognize. This includes:

Jaw pain or tenderness: Many people report jaw pain or tenderness with natural daily activities like talking and chewing. The pain may present as an aching or throbbing sensation.
Headaches and facial pain: Migraines or headaches may occur, as the TMJ and surrounding facial muscles may become strained.
Clicking or popping sounds in the jaw: In some cases, clicking or popping sounds of the jaw may indicate that the TMJ is damaged or not functioning properly.
Jaw locking or limited movement: Trouble opening, closing, or moving the mouth can be a sign of TMJ issues. The jaw may even become locked, known as tetanus, in which the jaw muscles have a hard time allowing the mouth to open or close.
Earaches and tooth sensitivity: Since the TMJ is located near the ears and jaws, pain may radiate to the ear canals and teeth.

What complications can arise from TMJ dysfunction?

TMJ dysfunction could cause various complications. Common complications from TMJ dysfunction include teeth grinding or clenching, lock jaw, headaches, earaches, facial pain, tinnitus, dizziness, and difficulty chewing and speaking, and sleep issues.

Diagnosis of TMD

TMDs can be diagnosed by dentists or healthcare providers through a comprehensive evaluation. Diagnosis often involves evaluation of your dental and medical history, a clinical examination, and imaging such as X-rays, MRI, CT scans to evaluate the TMJ and surrounding tissues and muscles. The clinical examination may involve testing how far you can open and close your mouth, palpation of the TMJ and surrounding muscles, and listening for abnormal sounds during jaw movement. Your existing signs and symptoms will also be evaluated and other possible conditions will be discussed.
