Causes for TMD

Causes for TMD are unclear as TMD usually involves more than a single symptom and rarely has a single cause.  TMD is believed to result from several factors acting together, including jaw injuries (trauma), and joint disease (arthritis).  Tooth clenching and grinding (bruxism) and head and neck muscle tension, while not scientifically proven to be a cause of TMD, may perpetuate TMD symptoms and often need to be controlled to reduce and manage TMD.  It is important for the TMD patient to understand that the disorder can be chronic in nature and highly dependent upon multiple factors including emotional stability.  Because there is no “quick fix” or immediate cure for TMD, the most successful and scientifically supported treatments focus on self-management and control of the aggravating factors.

ABNORMAL TMJ
ANTERIORLY DISPLACED DISC
WITH CHANGES IN SHAPE AND OTHER 
DEGENERATIVE CHANGES

Statistics indicate that the vast majority of TMJ problems are caused by trauma. By trauma, we mean an injury as obvious as a blow to the jaw with a fist or something as subtle as a whiplash injury from a car accident that causes direct trauma to the head or jaw.

The most common forms of trauma that cause TMD are: 
• Whiplash (cervical acceleration/deceleration) 
• Air bag deployment 
• Opening the jaw too wide / Biting on hard objects 
• A blow to the jaw 
• Bruxism / Clenching 


CONTRIBUTING FACTORS 
• Bad Bite (Malocclusion) 
• Orthodontics
• Ligament Laxity
• Stress 
• Systemic Diseases 

Other Orofacial Pain Disorders: 
There are a number of other pain disorders that are often confused with TMJ because they refer pain into the jaw and joint. Most common among these are: 
• Temporal Tendonitis (The "Migraine Mimic")
• Ernest Syndrome 
• Occipital Neuralgia 
• Trigeminal Neuralgia 
• Atypical Trigeminal Neuralgia 
• Atypical Face Pain 
• Neuralgia Inducing Cavitational Osteonecrosis (NICO)
