What Is A Crossbite_ Signs, Effects, and Treatment

Crossbite is one of the many commonly occurring dental problems affecting both children and adults. It is a form of teeth misalignment, whereby more than one tooth is not appropriately positioned. Crossbite can lead to several dental issues, too complex to handle. Rather than fall in the same line and in their rightful position, the teeth are packed too closely to the cheek and tongue.

If you have a crossbite, because of the alignment of the teeth, it will be difficult to bite food because your teeth would not fit together as they should; therefore, all bites will be distorted.

In a few cases, crossbite could be genetically inherited, if there’s a family member who had a crossbite, you have to seek orthodontic help to have your teeth inspected as soon as possible, especially if you notice any form of misalignment. Otherwise, crossbite could also be a result of circumstances you cannot handle, for instance, if you started developing permanent teeth while all your milk teeth have not fallen out.

All kinds of crossbite can cause unease and lead to dental complications such as pain in the jaws, and teeth loss. If left untreated, it may cause teeth chipping, and the enamel could wear off.

What Is A Crossbite?

Crossbite is a tooth condition where one or more teeth are placed in an irregular position. They can prevent jaws from fitting properly; this, in turn, makes speaking and eating a difficult task.

Crossbite, when ignored and not treated can cause complications to the jaws leading to abnormal growth of the jaws. This growth will make you look odd and will have a bad effect on the entirety of your facial form. Crossbite can also affect smiles and bring about low self-esteem.

Early loss of milk teeth, thumb sucking, using a pacifier or feeding bottle for a lengthy period, and growing adult teeth, when they are still losing baby teeth can cause crossbite in children. Therefore, children around age 6 and 7 should be given orthodontic care to check if they may develop any issues related to crossbite in the future.

There are two types of crossbite: Anterior Crossbite and Posterior Crossbite.

Anterior Crossbite

Anterior crossbite happens when the teeth beneath the front area point out more than the front upper teeth. This kind of crossbite affects only a small section of the world’s popularity, both children and adults. It can be treated if you consult your orthodontist.

Posterior Crossbite

Posterior crossbite is abnormal bites in the back teeth, which include the premolars and molars. It happens when the back teeth at the bottom protrude further than the top teeth at the bottom. The crossbite in this case takes place on both or just one side of the mouth.

They are more common as they affect a lot more people in the world’s population. It can be corrected using orthodontic methods of treatment, especially the use of an expander.
