Why Do I Clench My Jaw?

Clenching is multifactorial and is associated with many conditions. While the exact etiology is not clear, the following conditions are listed as possible causes of jaw and teeth clenching: 

  1. Stress: this may be one of the most common causes for teeth clenching. This is 100% correct if you find your self clenching your teeth during daytime. However, stress can make night-time clenching worse. Night-time clenching is more likely to cause morning headache and facial pain. Therefore, Dr. Khalifeh recommend using stress reduction protocol to relief pain associated with stress induced jaw clenching.
  2. Genetics: this is more likely associated with night-time jaw clinching and teeth grinding. Several scientific studies revealed that night-time clenching which include both unconscious teeth grinding and jaw clenching is associated with missing Serotonin receptors in the trigeminal motor center. Therefore, using Selective Serotonin Re-uptake Inhibitors (SSRI) antidepressant medications may induce clenching jaw syndrome.
  3. Temporomandibular joint (TMJ) disorder also called TMD: TMJ dysfunction are multiple conditions affecting the jaw joint, the chewing muscles and associated ligaments and fascia. TMD can cause jaw pain which could increase stress level causing more clenching. In other words, clenching may cause TMD. On the other hand, TMD might cause clenching. It is a cycle of events that one problem will induce the other problem. Treating TMD will certainly help ease jaw clenching. TMJ disorder include: osteoarthritis, rheumatoid arthritis, myalgia and myofasial pain syndrome. These conditions are not limited to the TMJ, they can affect other body joints and muscles.

Other Causes of Jaw Clenching

  1. Drugs and Medications: as mentioned earlier, Selective Serotonin Reuptake Inhibitor (SSRI) Medications used to treat depression may induce clenching as part of their side effects. Therefore, switching the medication may help stop and relief clinching symptoms. Central Nervous System stimulants such as Amphetamines and caffeine may also cause clenching and teeth grinding.
  2. Oro-motor disorders such as Dystonia: Dystonia causes one or more of the muscles to contract unwillingly causing pain and repetitive movement. This neurologic condition can cause social distress. BOTOX for jaw clenching is one of the most effective treatments available for dystonia.
  3. Tetanus: this is a life-threatening bacterial infection contracted when infected soil touches an open wound. Tetanus can cause sever skeletal muscles contraction including the jaw muscles. It can also cause damage to the heart and paralyze the breathing muscle. An effective vaccine is available for tetanus. It’s highly recommend that everyone get the tetanus vaccine and the boosters every few years as recommended by the CDC.
