What Is Temporomandibular Joint Disorder (TMD)?

Temporomandibular joint disorder (TMD) refers to a group of related disorders that result from problems with the jaw or jaw joint, or facial muscles involved in jaw movement. TMD can cause discomfort and pain that may be constant or intermittent. These disorders are often incorrectly referred to as TMJ, which refers only to the temporomandibular joint itself. You can learn more by speaking with Dr. Smith or Dr. Hiebert.

Symptoms Of TMD

The symptoms of TMD may arise from any number of easily identifiable and treatable causes. This is including sinus infections, tooth decay or gum disease. With these conditions comes an array of symptoms, such as:

  • Chronic facial pain in the face and jaw
  • Limited ability to open the mouth wide
  • Chronic facial pain in or around the ear
  • Clicking or popping noises when opening the mouth
  • Swelling on one or both sides of the face
  • Headaches and neck aches
  • Difficulty chewing
  • Uncomfortable bite

The Causes of TMD

TMD | TMJ Headaches Portland OR
There are many causes of TMD and many are out of peoples control. Most of the causes include trauma to the head or neck, or a natural misalignment of the upper or lower jaw. The common causes are:
  • Misalignment of the upper and lower jaws
  • Trauma to the head or neck
  • Clenching or grinding of the teeth
  • Bad bite or missing teeth
  • Arthritis
  • Bruxism

Bruxism Treatment

Teeth-grinding also known as bruxism, occurs when the jaws are clenched and the teeth grind against one another. Stress and anxiety are often blamed, but sleep disorders, abnormal bite, and missing or crooked teeth may also be causes. If left untreated, bruxism can lead to headaches, a sore jaw, or painful, loose or fractured teeth. It may sometimes lead to TMD.

TMJ Headaches & Migraines

Many can not believe that your jaw could be the reason for your headaches, however, it can. The TMJ, or temporomandibular joint, is a connective hinge from your jaw to your skill. This hinge allows us to do so many things including talking, laughing, chewing, the movement of our jaw up and down and side to side. This connection, if misaligned can cause a variety of symptoms, including headaches.

What Causes TMJ Headaches?

The temporomandibular joint combines a hinge action with sliding motions. The bones that work together are covered with cartilage and are separated by a small shock-absorbing disk. This keeps the movement of our jaws fluid and smooth.TMJ headaches are a part of the disorder and are simply a byproduct of different factors creating stress and pain in the joint:

  • Arthritis
  • Congenital alignment problems
  • Jaw alignment problems
  • Jaw injury
  • Teeth clenching
  • Teeth grinding
  • Worn-down teeth creating bite issues

TMJ Symptoms

Headaches originating from TMJ won’t have the same symptoms that severe headaches and migraines can have which include nausea, sensitivity to light or sound, and fatigue. But a TMJ headache can trigger a migraine if the patient is susceptible to developing them. It’s important to track your symptoms and note the differences between a tension headache and a headache brought on by TMJ. TMJ headaches will usually have other accompanying symptoms:

  • Difficultly opening and closing your mouth
  • A cracking or grinding sound
  • Facial tenderness and pain
  • Stiffness in the joint
  • Earaches

TMJ Treatment

Treating the symptoms of a tension headache won’t help with TMJ headaches. It can mask the pain, but the underlying causes will still be there and headaches will continue. At NW Heights Dental, we treat the TMJ. A variety of approaches are used to treat it from relaxation exercises at home to anti-inflammatory medications, from traditional dental work to creating a splint for nighttime use.

At NW Heights Dental, we’ve had good luck using night guards to keep patients from grinding their teeth. But sometimes, it’s a process of trial and error; we’ll try a certain approach and if it doesn’t have the desired effect, we’ll move to the next option. Methods for treating TMJ:

Cosmetic dentistry — To correct alignment, we can replace missing teeth with dental implants or bridges, crown overly worn teeth, or move the teeth with orthodontics. This can involve widening constricted arches.

Splints or night guards — Night grinding and clenching is often a main factor in TMJ. To combat this, it’s important to put the jaw in the correct position at night. To do this, we fabricate plastic mouthpieces that fit over the upper and lower teeth. Patients usually wear them at night.

Exercises — Tightening the jaw muscles and clenching the teeth is a common cause of TMJ problems. We have various jaw exercises that stimulate and relax the jaw muscles.

Medication — Muscle relaxants and anti-inflammatory medication can be effective.

Lifestyle changes — Stress and anxiety are often root causes; stress reduction techniques are important.

Transcutaneous electrical nerve stimulation (TENS) — A small wand delivers small electrical pulses to the jaw muscles. These pulses stimulate the nerves, encouraging the muscles to relax and the jaw to fall into alignment.

TMJ Pain Relief

More extensive corrective treatments may take the form of surgery or injections for pain relief. Surgery for TMD may include arthroscopy or open-joint surgery. Some of the treatments may include:

  • Arthrocentesis
  • Stress-reduction exercises
  • Muscle relaxants
  • Low-level-laser therapy
  • Mouth protectors to prevent-teeth grinding
  • Change in diet to soft foods
  • Heat/ice packs
  • Avoidance of extreme jaw movements
