Causes of TMD – Southern Maine Neuromuscular Dentistry

Any disturbance between the teeth, muscles, and joints in the jaw can trigger neurological impulses, which in turn can cause painful TMJ dysfunction.

Additionally, stress can trigger pre-existing conditions.

Some of the causes of TMD include:

  • Improper bite
  • Tooth and jaw misalignment
  • Trauma/head injury
  • Excessive yawning, or other periods where the mouth is open too wide for prolonged periods of time.
  • Clenching or grinding of teeth
  • Loss of teeth, especially the back molars
  • Cervical traction involving the head, jaws and neck
  • Compromised tongue position
  • Upper airway constriction
  • Poor posture
  • Arthritis

Additionally, there are some dental-specific causes of TMD. They are:

  • Crowded teeth
  • Narrow arches
  • Crossbites
  • Unlevel bite planes
  • Gumline tooth erosion
  • Generalized tooth sensitivity
  • Enamel cusp fractures
  • Porcelain crown fractures
  • Deep overbite
