An open bite malocclusion is a type of dental and facial irregularity that occurs when the upper and lower teeth do not make contact when the jaws are closed.

This can cause the tongue to rest between the teeth, and can also lead to problems with biting and chewing.

An open bite can be caused by a variety of factors, including genetics, habits such as thumb sucking or prolonged pacifier use, and environmental factors such as prolonged use of a pacifier or bottle. An open bite malocclusion can lead to problems with speech, chewing and biting, as well as problems with the temporomandibular joint (TMJ), which is the joint that connects the jaw to the skull. It can also affect the overall appearance of the face and can have a negative impact on self-esteem and confidence.

Treatment options for an open bite include orthodontic treatment with braces or clear aligners, along with a jaw surgery called maxillomandibular advancement (MMA) when necessary. Additionally, addressing the habits that cause the open bite, like thumb-sucking or prolonged pacifier use, can be helpful in preventing or reducing the malocclusion. As with any malocclusion, an accurate diagnosis and a personalized treatment plan is important and the orthodontist is the best suited professional to provide it.
