Dental mobility

Why do teeth move?

Tooth mobility is an ailment where one or more teeth that were originally well seated in their sustaining tissues (the periodontium) begin to present mobility within their alveolus. This can be caused by many possible reasons.

We must remember that teeth normally present a slight imperceptible mobility even in perfect health conditions, a particular trait made possible by the periodontal ligament. Thanks to the presence of the connective fibres that stand between the tooth and the alveolar bone it is in fact possible to create a dynamic structure ensuring correct management of occlusal force, making the risk of dental fractures minimal.

Tooth mobility must be considered pathological when it is no longer normal, when it becomes perceptible, quantifiable and therefore a symptom of a periodontal disease.



Causes for dental mobility: periodontitis

One of the main causes for dental mobility is periodontitis, more commonly known as “pyorrhea,” an infection that causes a progressive destruction of the tissues supporting the teeth.

Another cause that can lead to dental mobility is occlusal trauma, i.e. the presence of excessive or poorly distributed occlusive forces on one or more dental elements. This provokes mechanical damage to the periodontium and threatens its imperviousness to bacteria, causing a rapid absorption of the periodontal tissues.

The occlusal trauma can cause: the migration of teeth to non-physiological positions, the fanning out of the teeth, the increase in diastemas, or when the mobility increases, the loss of one or more teeth.

To solve the problem of tooth mobility it is necessary to eliminate all the causes that have led to it.

Periodontitis must be cured with mechanic scaling, i.e. a careful root surface debridement carried out with the help of a surgical microscope and through the elimination of bacteria with an assisted laser treatment.

Furthermore it is important to handle the occlusion in cases of traumatisms, to ensure a correct and speedy healing of all tissues involved, with the aim of returning periodontal support to the damaged teeth.

Feeling your teeth move is always a signal that must not be ignored.

If your teeth move you must visit your dentist. They will be able to evaluate the situation and choose the most suitable therapy. In this case time is of the essence.

It is always a good idea to undergo periodic periodontal check-ups, even when you are in perfect health, because prevention is always the best therapy. Especially when dealing with diseases such as periodontitis, which takes a lot of time and money and work to treat.
