Surprising Causes of TMJ Disorder

More than 10 million Americans suffer from TMJ (temporomandibular joint) disorder (TMD), which is a result of chronic stress on the TMJ. Many cases of TMD are a result of a misaligned bite or teeth grinding (bruxism). However, there are several other lesser known causes of TMD. Kois Dentistry discusses some of these surprising causes in this blog post.

Drug Use

Numerous studies have found that amphetamines like cocaine can lead to clenching and grinding of the teeth. Continuous grinding can put stress on the muscles and ligaments that control TMJ functionality.

Poor Posture

Poor posture and consistently slouching can cause the lower jaw to move forward, causing it to misalign with the upper jaw. Bad posture can also aggravate the jaw, which can lead to a slew of TMD symptoms including earaches, pain and soreness.


Researchers have identified stress and anxiety as primary causes of teeth grinding. Grinding or clenching your teeth can cause wear and tear on your teeth, as well as jaw misalignment and pain. If you are experiencing chronic jaw and mouth pain due to teeth grinding, try to minimize your stress levels. Meditating and exercising can help reduce stress. It is also wise to schedule an appointment with your dentist to determine whether you are in need of any dental work due to teeth grinding.

Super Sizing It

Upgrading your meal to a large or extra-large may end up costing you more than just a few cents and calories. Opening your mouth too wide when biting down on food can put stress on your jaw muscles and ligaments; so much, in fact, that it leads to, or worsens, TMD symptoms. If you have problems opening your mouth wide or experience pain when chewing, try cutting your food into smaller, more manageable bites.
