TMJ Disorder Cary, NC

The temporomandibular joint (TMJ) is the hinge joint that connects the lower jaw (mandible) to the temporal bone of the skull. Temporomandibular disorders (TMD) occur as a result of problems with the jaw, jaw joint, and surrounding facial muscles that control chewing and moving the jaw.

This joint is immediately in front of the ear on each side of your head. The joints are flexible, allowing the jaw to move smoothly up and down and side to side and enabling you to talk, chew, and yawn. Muscles attached to and surrounding the jaw joint control its position and movement.

What Causes TMD?

The cause of TMD is not clear, but dentists believe that symptoms arise from problems with the muscles of the jaw or with the parts of the joint itself.

Injury to the jaw, temporomandibular joint, or muscles of the head and neck such as from a heavy blow or whiplash can cause TMD. Other possible causes include:

  • Grinding or clenching the teeth, which puts a lot of pressure on the TMJ
  • Dislocation of the soft cushion or disc between the ball and socket
  • Presence of osteoarthritis or rheumatoid arthritis in the TMJ
  • Stress, which can cause a person to tighten facial and jaw muscles or clench the teeth

What Are the Symptoms of TMD?

People with TMD can experience severe pain and discomfort that can be temporary or last for many years. More women than men experience TMD and TMD is seen most commonly in people between the ages of 20 and 40.

Common symptoms of TMD include:

  • Pain or tenderness in the face, jaw joint area, neck and shoulders, and in or around the ear when you chew, speak or open your mouth wide
  • Limited ability to open the mouth very wide
  • Jaws that get “stuck” or “lock” in the open- or closed-mouth position
  • A tired feeling in the face
  • Difficulty chewing or a sudden uncomfortable bite as if the upper and lower teeth are not fitting together properly)
  • Swelling on the side of the face

Other common symptoms include toothaches, headaches, neck aches, dizziness, earaches and hearing problems.

How Is TMD Diagnosed?

Because many other conditions can cause similar symptoms including a toothache, sinus problems, arthritis, or gum disease your dentist will conduct a careful patient history and clinical examination to determine the cause of your symptoms.

He or she will examine your temporomandibular joints for pain or tenderness; listen for clicking, popping or grating sounds during jaw movement; look for limited motion or locking of the jaw while opening or closing the mouth; and examine bite and facial muscle function. Sometimes panoramic X-rays will be taken. These full face X-rays allow your dentist to view the entire jaws, TMJ, and teeth to make sure other problems aren’t causing the symptoms. Sometimes other imaging tests, such as magnetic resonance imaging (MRI) or a computer tomography (CT), are needed. The MRI views the soft tissue such as the TMJ disc to see if it is in the proper position as the jaw moves. A CT scan helps view the bony detail of the joint.

Your dentist may decide to send you to an oral surgeon (also called an oral and maxillofacial surgeon) for further care and treatment. This oral healthcare professional specializes in surgical procedures in and about the entire face, mouth and jaw area.

JVA

Joint Vibration Analysis or JVA allows the dentist to listen to the noises the joint makes when one opens and closes. Those noises that are picked up by the “headphone” are translated into electrical readings that allow the dentist to formulate a better idea of what is happening during that motion. We can determine the health of a joint from presence of absence of joint sounds, i.e. muscular problems vs. internal capsular problems.

Additional TMJ Technology

In order to assist our patients in finding the best TMD treatment in the Cary and Raleigh area, we have invested a great deal into modern dental technologies that allow for in-house diagnostics.

Cone Beam CT

The cone beam CT is an advanced piece of TMJ treatment technology that allows us to easily visualize in 3D sinus and temporal bone structures with a fraction of the radiation dose of conventional machines. The machine is designed to be open and upright, minimizing the potential of claustrophobia. Dr. Ferzli will be able to rapidly review your imaging studies and the in-house imaging ensures the quality of your diagnostic image.

Electromyography (EMG)

The EMG allows us to measure electrical activity of muscles. In many TMD cases, muscles are overworked. Measuring their electrical allows us to monitor. We use this machine to find and describe these electrical properties in the muscle or nerve to help us diagnose your problem.

Jaw Tracker

The Jaw Tracker is used to track jaw movements by recording incisor-point movements in three dimensions. Using a small magnet that is attached to the labial (lips) surfaces of the centrally located incisors, this system helps us to track components of jaw movement. The process is quick and easy and allows an accurate diagnosis without the patient feeling claustrophobic.

MLS Laser

MLS Laser therapy is used to treat patients with orofacial pain, and is the most advanced laser therapy system on the market. The multiwave system offers a greater benefit to patients than that of any one wavelength laser alone. Other benefits include intense anti-inflammatory and anti-edemic (reduces swelling) effects, as well as a strong analgesic (painkilling) effect.
