What is a Crossbite?

A crossbite is another case of teeth misalignment. The teeth do not fit properly when the mouth is closed. In this condition, the upper teeth are aligned behind the lower teeth. It is in a way that the set of lower teeth is positioned in front of the upper ones.

Understanding a crossbite by differentiating and treating this malocclusion

A crossbite is a frequently encountered form of malocclusion, often mistakenly conflated with an underbite. In contrast to an underbite, wherein both the lower teeth and jaw protrude forward, a crossbite primarily impacts a subset of lower teeth without affecting the entire jaw.

While not as severe as an underbite, addressing a crossbite is imperative as it can lead to issues during chewing or eating and potentially result in complications related to facial features and jaw discomfort. Proactive treatment is essential to prevent these complications from arising.

During your consultation visit, your local provider will examine your teeth to determine your condition and recommend a suitable treatment plan. For severe crossbite issues, you might need jaw alignment surgery. Once you are done with the surgery, consult with your doctor to begin your clear aligner treatment.
