TMJ Causes

Unbalanced bite

A bad bite can result in soreness and can be a leading cause of TMJ. The obvious signs include an under-bite or an over-bite. An unbalanced bite could result from one cause, or a combination of factors. Allergies during childhood, thumb sucking, old dentistry that needs to be replaced, or the shifting of teeth due to tooth loss can all lead to a bad bite.

Airway issues

Airway issues can cause TMJ pain, an improperly formed jaw, and bite issues. If you have an unbalanced bite, your tongue can’t sit where it should, which as a result can block air from getting to your lungs. Improper breathing may be due to childhood allergies. When a child is constantly congested, the tongue drops down allowing air to pass over it. The tongue is no longer in balance and the upper jaw’s growth changes over time. This can result in a compromised breathing airway.

Skull deformation

Pressure and force exerted on a baby’s head during birth affects the shape and development of the skull and the bones in the head and face. If there is a misalignment of the bones, muscles, or ligaments, this can alter the development of the TMJ. It can also result in the misalignment of jaws and skull bones, causing an unbalanced bite.


The fact is that your jaw structure, teeth positioning, and entire facial composition are inherited. This can include the sensitivity to your environment leading to allergies and congestion. If you inherited a small jaw or if your teeth are too large to fit your mouth, the result is a bad bite and misaligned jaw.

Injury or trauma

An injury or trauma to your jaws from an accident or any intense physical impact, can lead to damage to your muscles or joints. Any time your body absorbs the impact of a serious blow, it transfers throughout the rest of your body, altering the function of the muscles and joints in your head, neck, and face. This results in discomfort and irritation related to TMJ.

Unbalanced dentistry

Even if you have gone through orthodontic work to straighten your smile, there could still be invisible problems. You can have a perfectly straight set of teeth but still be suffering from TMJ symptoms and have a misaligned bite.
