Cross bite: The most common malocclusion

Crossbite is one of the most common oral malocclusions among patients. Malocclusion is the term used by dentists (orthodontists) to define an alteration in the alignment of the teeth that makes correct occlusion impossible (fitting of the upper and lower teeth).

Crossbite alters the functionality and aesthetics of the teeth, but with correct and timely orthodontic treatment, it can be completely corrected. Time plays a very important role when we talk about this type of malocclusion, because the sooner the alteration is detected and the treatment is carried out, the faster and simpler it will be.

This malocclusion can present three main types of patterns: skeletal, dental or both at the same time. For each case the treatment is different, so it is necessary to have the diagnosis of an expert orthodontist for the best choice of treatment.

Depending on the disposition of the teeth, the following types of crossbite are presented:


This malocclusion affects the patient’s health at various levels ranging from symptoms such as headache to injuries of the joint that joins the jaw with the jaw, some facial deformities and wear of teeth that are not in their ideal position.

When we talk about cross-bite, it is important to emphasize that treatment in children is much simpler and less invasive than in adults. That is why it is important to take them to the consultation of an expert orthodontist who can solve the problem even with the simple change of bite habits, breathing or the position of your tongue.

In the case of adults, the treatment can become much more complicated because the growth and development of the bone position has already finished. Therefore, if the expansion that must be made to solve the cross bite is severe, surgery must be performed to achieve the necessary expansion of the palate.
