Temporomandibular Joint Disorder (TMD)

Teeth Grinding and Headache Prevention

Annually, over 50 million Americans have headaches so severe that they seek medical help. Most of these people state that their head pain is a disruptive force in their daily lives. The majority of these patients suffer from Temporomandibular Joint Disorder (TMD).

TMD is a group of separate but related disorders of the temporomandibular joint and all the associated muscles, ligaments, nerves, etc. Unfortunately, TMD's are the most frequently misdiagnosed of the medical/dental conditions.

After an examination and appropriate x-rays, Dr. Crawford will help identify the source of the discomfort. He will then recommend what treatment is needed for your condition and begin moving forward.

NTI Appliance

The NTI prevents:

  • Migraine pain
  • Tension-type headache pain
  • Jaw disorders (TMD)
  • Bruxism (teeth grinding)

Without drugs or surgery.

How the NTI Tension Suppression System Works 

TMD, bruxism, chronic tension headaches, migraine...
Did you ever wonder what these symptoms—which all can make your life miserable—have in common
They all are controlled and/or moderated by the Trigeminal Nerve.

An overused Trigeminal Nerve can cause hyperactivity that results in excessive jaw muscle contraction during certain stages of sleep. This causes intense jaw clenching and/or vigorous teeth grinding. The Trigeminal Nerve is also involved with chronic headaches, migraines or TMD.

The basic principle behind the NTI-tss

"NTI" refers to the nocturnal inhibition of the harmful sensory input to the Trigeminal Nerve. The NTI device is a dental mouthpiece that Dr. Crawford provides for the patient. The NTI fits securely on either the patient's upper or lower front teeth while asleep. The patient's unique bite dictates the design of the NTI device.

The NTI device inhibits the canine and molar teeth from touching anything during sleep. This reduces the pathological intensity of jaw clenching and teeth grinding and prevents any resultant TMD or headaches.

Difference between traditional night guards and NTI-tss

The traditional treatment for bruxism has been a night guard—a plastic appliance worn in the mouth similar to an athletic mouth protector. The night guard covers the teeth of one arch, which allows the patient to bite on plastic so there is no tooth-to-tooth contact while biting.

It is key that the molars and canines do not touch anything in order to sufficiently reduce jaw clenching. Both night guards will protect the teeth from wear but the NTI-tss will also prevent TMD and headache pain by preventing canine and molar contact.
