Maxillary Atresia

Maxillary atresia is an insufficient development of the upper bone of the mouth, which ends up narrower than expected and reduces the space available for the teeth and for the passage of air.

How it shows up: It is usually noticed as a narrow palate, dental crowding, crossbite, or difficulty breathing well through the nose. In many cases it is identified during childhood or adolescence.

Common causes: It may be related to inherited factors of facial growth, to prolonged mouth breathing, or to habits such as sustained thumb sucking.

Who to see? The orthodontist is the right professional to assess the shape of the upper jaw and the bite; the earlier facial growth is reviewed, the better the follow-up options. If you notice any of these signs in your child or in yourself, it is worth scheduling an evaluation with this specialist to understand the full picture.
