Understanding TMJ Disorders
The temporomandibular joint (TMJ) is one of the most complex joints in the human body. Located on each side of your head just in front of the ears, these joints connect your lower jaw (mandible) to the temporal bone of the skull. They work together with muscles, ligaments, and a small cartilage disc to allow you to open and close your mouth, chew, speak, and yawn. When something goes wrong with this system — whether from injury, disease, or chronic stress — the result is a temporomandibular disorder (TMD), commonly referred to as a "TMJ disorder."
At California Oral and Implant Surgery in California, MD, Dr. John McElveen is a board-certified oral and maxillofacial surgeon who specializes in diagnosing and treating the full spectrum of TMJ disorders. We serve patients from Lexington Park, Leonardtown, Great Mills, Hollywood, Prince Frederick, La Plata, Waldorf, and across Southern Maryland.
How Does the TMJ Work?
Each TMJ contains a small, smooth disc of cartilage that sits between the jawbone and the skull. This disc acts as a cushion, absorbing shock and allowing the joint to glide smoothly when you open your mouth. The joint is supported by muscles of mastication — the masseter, temporalis, and pterygoid muscles — which coordinate jaw movement. A problem with any part of this system — the disc, the bone surfaces, the muscles, or the ligaments — can cause pain and dysfunction.
Common TMJ Symptoms
TMJ disorders present a wide range of symptoms. Some patients experience mild, intermittent discomfort, while others suffer from severe, chronic pain that affects daily life. Common symptoms include:
- Jaw pain or tenderness — especially when chewing, speaking, or yawning
- Clicking, popping, or grating sounds — when opening or closing your mouth
- Jaw locking — the jaw gets "stuck" in an open or closed position
- Limited range of motion — difficulty opening your mouth fully
- Ear pain or fullness — often mistaken for an ear infection
- Headaches — especially in the temples, often worse in the morning
- Neck and shoulder pain — tension radiating from the jaw muscles
- Changes in bite — teeth that no longer fit together properly
What Causes TMJ Disorders?
TMJ disorders can develop from a single event or from a combination of factors over time. The most common causes include:
- Bruxism (teeth grinding or clenching): Chronic clenching — especially during sleep — places extreme pressure on the TMJ, wearing down the cartilage disc and straining the muscles.
- Trauma or injury: A blow to the jaw, whiplash, or even prolonged dental work can damage the joint or displace the disc.
- Arthritis: Osteoarthritis (wear-and-tear degeneration) or rheumatoid arthritis (autoimmune inflammation) can destroy the cartilage surfaces of the joint.
- Disc displacement: The cartilage disc can slip out of its normal position, causing clicking, locking, and pain.
- Malocclusion (bite misalignment): An uneven bite forces the jaw muscles to compensate, creating chronic strain on the TMJ.
- Stress: Emotional and physical stress leads to unconscious jaw clenching and muscle tension, a major contributor to TMD symptoms.
How TMJ Disorders Are Diagnosed
Accurate diagnosis is the foundation of effective TMJ treatment. During your consultation at our California, MD office, Dr. McElveen will conduct a thorough evaluation including:
- Clinical examination: Palpation of the jaw joints and muscles, assessment of jaw range of motion, and listening for clicking or crepitus (grinding sounds)
- Dental evaluation: Checking your bite alignment and looking for signs of grinding or clenching
- Imaging: Panoramic X-rays, cone-beam CT (CBCT) scans, or MRI to visualize the joint structure, bone surfaces, and disc position
- Medical history review: Understanding contributing factors such as stress, posture habits, previous injuries, and medication use
Conservative (Non-Surgical) Treatment
The majority of TMJ disorders respond well to conservative treatment. Dr. McElveen always begins with the least invasive approach and escalates only when necessary:
- Custom oral appliances (night guards/splints): A custom-fitted occlusal splint worn at night prevents teeth grinding and repositions the jaw to reduce joint pressure. This is one of the most effective first-line treatments.
- Medications: NSAIDs (ibuprofen, naproxen) for pain and inflammation, muscle relaxants for spasm, or low-dose tricyclic antidepressants for chronic pain management.
- Physical therapy: Targeted jaw exercises, ultrasound therapy, and manual techniques to improve range of motion and reduce muscle tension.
- Trigger point injections: Local anesthetic or corticosteroid injections directly into painful muscle trigger points for immediate relief.
- Botox injections: Botulinum toxin injected into the masseter or temporalis muscles to reduce clenching force and relieve chronic muscle pain.
Surgical Treatment Options
When conservative treatments have been exhausted and symptoms persist, surgical intervention may be recommended. Dr. McElveen performs the full range of TMJ surgical procedures:
- Arthrocentesis: A minimally invasive procedure where sterile fluid is flushed through the joint to remove inflammatory byproducts and break up adhesions. Performed under local anesthesia or IV sedation, with most patients returning to normal activities within a few days.
- Arthroscopy: A small camera is inserted into the joint through a tiny incision, allowing Dr. McElveen to visualize the joint, remove scar tissue, reposition the disc, or smooth irregular bone surfaces. Recovery is typically 1–2 weeks.
- Open joint surgery (arthroplasty): For severe cases — such as ankylosis (joint fusion), tumors, or significant structural damage — open surgery allows direct access to repair, reshape, or replace damaged joint components.
- Total joint replacement: In rare cases of end-stage TMJ disease, the joint may be replaced with a prosthetic device to restore function and eliminate pain.
Self-Care Tips for TMJ Relief
- Eat soft foods and cut food into small pieces — avoid chewy, hard, or crunchy foods
- Apply moist heat or ice packs to the jaw for 15–20 minutes at a time
- Practice jaw relaxation — keep lips together and teeth apart during the day
- Avoid wide yawning, gum chewing, and resting your chin on your hand
- Maintain good posture — especially if you work at a desk or computer
- Practice stress-reduction techniques such as deep breathing, meditation, or yoga
When to See a TMJ Specialist
If you experience persistent jaw pain, frequent headaches, or difficulty opening your mouth, don't ignore the symptoms. Early treatment can prevent the condition from worsening and avoid the need for surgery. You should seek evaluation if:
- Jaw pain or clicking has lasted more than two weeks
- Your jaw locks open or closed
- Over-the-counter pain relievers are not providing adequate relief
- Pain is affecting your ability to eat, sleep, or concentrate
