The impact of bite on the health of the jaw joints

Incorrect bite is one of the main risk factors for the development of pathology of the temporomandibular joint, a joint that has a complex and, perhaps, the most delicate, delicate structure in the human body. The development of the pathology of the temporomandibular joint, in turn, leads to the development of problems with bite and evenness of the teeth. Let’s understand why this is happening and what is

The temporomandibular joint is the point of attachment of the mandible to the skull. It is he who is responsible for the mobility of the lower jaw, i.e. the ability to eat, talk, yawn, etc.

When can problems arise?

If the bite is such that the upper teeth hold the lower jaw in a more backward position, it turns out that in the mandibular joint, the lower jaw is also displaced back. In the back of the joint there is a connective tissue, which, due to its friability, cannot prevent pressure and bulges from the displacement of the lower jaw back.

This tissue contains numerous nerves and vessels. When the mandible moves back in the joint, these nerves are compressed, which causes pain, and can also cause other symptoms, Kosten’s syndrome develops. .

What sensations does a person experience with this pathology?

Pain: in the region of the temporomandibular joint itself, in the neck, pain and burning in the tongue and pharynx, pain in the ears and behind the ear, headaches, pain in the occipital region, pain in the paranasal sinuses, pain may spread to eye area
Clicking, crunching, stiffness of the lower jaw
Constraining tension of masticatory muscles
Tinnitus, stuffy ear sensation, hearing loss
Dryness in the oral cavity and larynx or, conversely, increased salivation
When the lower jaw is displaced back in the joint, the vessels are also squeezed and they will no longer fill with blood. Therefore, the joint, to which they were supposed to deliver nutrients and oxygen, receives less of them. This leads to degradation and destruction of the joint. The part of the lower jaw that is involved in the formation of the joint is reduced in size due to lack of nutrients.

Nature planned the support of the lower jaw in space in such a way that the lower jaw had 2 zones of support: the teeth and the part of the skull involved in the formation of the joint with the lower jaw. If changes occur in the joint and the part of the lower jaw in contact with the skull decreases and loses height, then one of the points of support is already changing.

The lower jaw reactively begins to try to change its position, but the teeth try to keep it in the previous position. The lower jaw is a very massive and heavy bone formation. Teeth, on the other hand, were created by nature with the possibility of displacement (due to this, by the way, teeth can be moved during orthodontic treatment). As a result, the lower jaw, which no longer has one stable position, drags the teeth with it, which begin to move unpredictably and chaotically. So, problems with bite cause pathology of the temporomandibular joint, and the problem with the temporomandibular joint further exacerbates the problem with bite and position of the teeth.

In turn, problems with the temporomandibular joint will again increase. Such situations, when problems accumulate like a snowball, are often encountered in medicine, almost all chronic diseases in the body are formed according to this mechanism. This development of pathology is called in medicine “vicious circles”. It is very important not to start problems (!) and to get out of a series of these repetitive cycles in time, reinforcing themselves with each repetition, that is, to break these vicious relationships as quickly as possible.
