Temporomandibular Joint Disorders (TMJ) Disorder

TMJ disorder is a complex syndrome that affects the joint connecting the lower jawbone to the skull. According to the American Academy of Orofacial Pain, approximately 5% to 12% of the global population experiences symptoms related to TMJ. A study published in the Journal of Oral Rehabilitation indicates that the prevalence of TMJ in some Asian countries ranges from 21% to 31%, with women aged 20 to 40 being at higher risk due to hormonal factors and stress. TMJ causes dull or sharp pain in the jaw, temples, and face, negatively impacting various daily activities such as eating, communicating, and even sleeping. Furthermore, this condition can lead to psychological stress due to prolonged pain. So, what exactly is TMJ, and why has it become so prevalent? Let’s explore this with Optimal365 Chiropractic.

What is TMJ Disorder?

TMJ disorder is a dysfunction syndrome affecting the joint, muscles, and ligaments surrounding the connection between the jawbone and the skull. The temporomandibular joint acts like a sliding hinge, allowing the lower jaw to move up and down and side to side, enabling functions such as chewing, speaking, yawning, and opening the mouth. Under normal circumstances, this joint operates smoothly, thanks to the articular disc that cushions and distributes force. However, when the articular disc becomes displaced, inflamed, or degenerated, along with muscle spasms of the jaw, it leads to characteristic symptoms of TMJ, such as pain, difficulty opening the mouth, limited jaw movement, and clicking or popping sounds when chewing or moving the jaw.

Symptoms of TMJ Disorder

TMJ disorder often manifests through various symptoms, depending on the severity and underlying causes. Here are some of the most common signs of TMJ:

• Pain or Discomfort: A feeling of pain or sharp discomfort in the area where the lower jaw connects to the skull, which may radiate to the surrounding areas, including the ears, face, and neck.
• Jaw Stiffness or Locking: A sensation of stiffness in the jaw or a “locked jaw” when opening the mouth wide, chewing, or speaking, which limits the ability to open the mouth fully.
• Muscle Tension and Pain: Tension and pain in the muscles surrounding the temporomandibular joint.
• Clicking, popping, or cracking sounds when moving the jaw are often signs of joint misalignment or changes in the joint structure.
• Jaw Misalignment: The upper and lower jaws do not align properly when biting, causing difficulties when chewing.
• Radiating Pain: Pain may radiate to the head or ears, leading to headaches, temple pain, migraines, or sharp pain in the ears.
• Ear Issues: Some individuals may experience ear problems such as tinnitus or hearing loss.
• Pain when eating hard, chewy foods or when chewing for a long time.
• Jaw Discomfort: Pain and discomfort in the temporomandibular joint can affect sleep quality, making it difficult for patients to fall asleep or causing them to wake up during the night.

Causes of TMJ

The common causes of TMJ disorders include injuries related to the jaw, joint, or head and neck area. This condition can occur due to various reasons such as physical trauma, strong impacts, or even stress and bad habits like teeth grinding. Among these, several causes of TMJ syndrome include:

• Direct injury to the jaw from accidents or sports injuries, which can lead to dislocation or damage to the structures surrounding the TMJ.
• Nervous tension, stress, and psychological pressure can lead to unconscious habits such as clenching the jaw or grinding teeth, and even involuntary jaw tightening, which can cause TMJ issues.
• Teeth grinding or clenching is the most common cause; grinding teeth while sleeping or tightening the jaw increases uneven pressure on the jaw muscles, leading to temporomandibular joint disorders.

• Some individuals may have asymmetrical TMJ from birth. Congenital misalignment of the TMJ can lead to temporomandibular disorders.
• The condition of uneven teeth or prolonged tooth loss that is not restored can cause uneven chewing forces, misalignment of the bite, and increased pressure on the TMJ and jaw muscles.
• Chewing food on one side or consuming excessively hard foods (such as chewing ice) creates an imbalance in the way the jaw muscles function, increasing the risk of developing TMJ disorders.

Diagnosis of Temporomandibular Joint Disorder (TMJ)

Several imaging methods can be used to diagnose Temporomandibular Joint Disorder (TMJ), including:

• X-ray: X-ray imaging allows the doctor to observe the bone structure of the jaw, the temporomandibular joint, and the teeth, as well as to assess the structure of the temporomandibular joint and determine the extent of any damage. This method can detect abnormalities such as bone spurs or changes in the shape of the joint. X-rays can be performed from multiple angles to provide a comprehensive view of the condition of the joint and surrounding structures.
• MRI (Magnetic Resonance Imaging): MRI provides detailed images of the soft tissues surrounding the temporomandibular joint, helping the doctor detect disc displacement, inflammation, abrasions, or damage to the ligaments and muscles around the joint.
• CT Scan: A CT scan provides detailed cross-sectional images of the bone structure of the temporomandibular joint, helping to detect fractures, joint displacement, or complex bone injuries. It assists in treatment planning and monitoring changes in the bone over time.

Treatment for TMJ

Home Treatment for Mild TMJ Disorder:

When TMJ syndrome is at an early stage, it usually causes only mild pain, discomfort, and fatigue. You can use home remedies to alleviate pain and improve your condition. These methods are typically carried out under the guidance of a physician:

• Pain Relievers: Medications such as ibuprofen and naproxen help reduce pain, inflammation, and swelling.
• Muscle Relaxants: These medications help relax the jaw muscles, alleviating tension and discomfort.
• Dietary Adjustments: Avoid hard and chewy foods, and limit the extent to which you open your mouth to reduce stress on the temporomandibular joint. Cut your food into smaller pieces to make chewing easier and lessen the pressure on the jaw. Avoid chewing gum, as these foods can increase pressure on the joint.
• Change Sleeping Position: Sleeping on your side helps reduce pressure on the temporomandibular joint. Additionally, using a soft pillow can help keep your head and neck aligned.
• Eliminate Bad Habits: Use a mouthguard to prevent teeth grinding. Avoid opening your mouth too wide when yawning or laughing.
• Cold and Heat Compresses: Use an ice pack on the temporal area and jaw for 10-15 minutes to reduce swelling and numb the nerves. After using a cold compress, you can switch to a heat compress to improve blood circulation and alleviate pain.
• Jaw Relaxation Exercises: Perform specialized exercises based on your condition, such as gently opening your mouth to enhance the flexibility of the temporomandibular joint. Additionally, gently massaging the temporal area and jaw can help relax the muscles and reduce tension.

Treating TMJ Disorders in Severe Cases:

When TMJ syndrome is in a severe stage, treatment requires more in-depth intervention and may include the following methods:

• Protective Occlusal Splint: An occlusal splint, also known as a bite guard, is a dental device specifically designed to fit over the teeth. The splint helps reduce pressure on the temporomandibular joint by adjusting the bite and preventing tooth wear from grinding during sleep, which protects the joint and reduces pain. The splint also aids in aligning the bite by positioning the teeth correctly.
• Nerve Stimulation with Transcutaneous Electrical Nerve Stimulation (TENS): This method uses a mild electrical current to affect the nerves around the jaw area. The primary purpose is to help relax the muscles, enhance blood circulation, and reduce pain sensation. TENS is a non-invasive technique commonly used to relieve muscle tension in the jaw and neck, thereby alleviating symptoms related to TMJ disorders.

• Orthodontics: Orthodontic treatment helps correct misalignments in the bite, such as crooked teeth or uneven occlusion. By changing the position of the teeth and the bite, dentists can reduce pressure on the temporomandibular joint, improving jaw function and alleviating TMJ disorder symptoms.
• Psychological Counseling: Psychological counseling plays a crucial role in treating TMJ disorders, as stress and psychological tension are primary causes of this condition. Through counseling, patients can learn how to manage stress and recognize harmful habits, such as teeth grinding during stressful times. Therapies like relaxation techniques, stress management, and cognitive-behavioral therapy can help reduce TMJ symptoms related to psychological factors.

Temporomandibular Joint Surgery:

When conservative treatment methods are ineffective, surgery on the temporomandibular joint (TMJ) may be considered. Currently, there are three main surgical techniques, and the choice will depend on the specific condition of the patient:

• Joint Aspiration: This technique is indicated when the TMJ is locked or stuck, causing difficulty in facial movement. After anesthesia, the doctor will insert a needle into the joint to remove debris or damaged tissue while adjusting the trapped cartilage disc.
• Arthroscopy: This method uses an arthroscope inserted through a small incision in front of the ear. The doctor will remove inflamed tissue or adjust the structure of the TMJ disc. Arthroscopy is a minimally invasive surgical technique that helps reduce the risk of complications and recovery time compared to open surgical methods.
• Joint Reshaping Surgery: This is another minimally invasive technique in which joint fluid is removed and injected into the temporomandibular joint (TMJ) to clean and eliminate inflammatory deposits.
• Open Joint Surgery: This is the last option when the above surgical methods are not feasible, especially when there is a high risk of nerve damage. Open joint surgery is considered in cases such as erosion of the TMJ bone structure, suspected tumors inside or around the joint, or when the TMJ has scarring or scattered bone fragments.
