Do you experience pain in your jaw? Perhaps radiating to your ear, face, neck, and even your shoulder? Does this coincide with difficulty opening or closing your mouth while talking, chewing, laughing or yawning, or your jaw locking? You may be experiencing a dysfunction in your temporomandibular joint (TMJ). The TMJ joins the lower and upper jaws and is the joint responsible for opening and closing your mouth, as well as any side to side movement of the lower part of the jaw (which is important for chewing and articulation of speech). You have a right and left TMJ. You can actually feel the movement of the joint by palpating just in front of the ears as you open and close your mouth. There is a disc that is in between the joint that enables a smooth gliding motion. If this disc does not glide properly, you may experience clicking or popping sounds.
There are a variety of factors that can cause or contribute to TMJ disorders, and often times it is a combination of factors that need to be addressed in order for treatment to be effective. Some of the common causes include the following:
1) Postural alignment.
If you maintain a prolonged posture over a period of time where the position of your head and neck is creating chronic muscle tension, this might affect the function of your TMJ.
2) Behavioural habits that create muscle tension around the jaw muscles such as grinding or clenching
your teeth, excessive gum chewing or biting your nails. A common underlying cause of poor habits can be stress related.
3) Trauma to the joint.
4) Arthritis in the joint.
5) Dental problems such as abnormal alignment of the teeth when the upper and lower jaws are
brought together (malocclusion).
6) Hormonal changes. Research suggests that estrogen levels can also play a role in TMJ pain (Craft, 2007.) Read more
