What are Cross-bites and Its Treatment Options?

Ever heard about crossbite? Do you know what causes crossbite? How can you tell if you have crossbite problems? According to Dr. Jisoo Shin, DDS of Vita Dental, millions of America suffer from crossbite but don’t know because of the insufficient information available of the subject. Crossbite is a dental situation in which one or more top teeth bite inside the lower teeth instead of the outside. It is a misalignment of upper teeth in relation to the lower teeth.

Causes of crossbite

The exact cause of crossbite is not known but it is believed to be a genetic problem. There is a disorientation in the chromosomal arrangement and this causes the teeth to overlap. Some crossbite situations are not natural and are caused by either illnesses in which the teeth move into a new position and arch over the lower teeth. Crossbite is very common in young children and even though one cannot outgrow the situation, naturally teeth will try and readjust for the best possible bite. This is however not the case for all individuals. Whereas some people’s teeth readjust with time, other people’s teeth don’t and the crossbite gets worse as they grow.

Types of crossbite

Depending on the location of the mouth, crossbite can take different forms and can involve the front teeth or the back teeth. There are two types of crossbite therefore; Anterior crossbite and posterior crossbite. Posterior crossbite occurs when the upper teeth fall inside the lower teeth on one side when you bite into something. A anterior crossbite or an underbite occurs when your top front teeth fall behind your lower front teeth when you try to bite into something. In some rare cases, individuals suffer from both forms of crossbite and experience double whammies because they experience even more difficulties biting and even chewing foods.

Effects of crossbite

There are very many problems associated with crossbite that affect people and the way they go about their daily activities. When left untreated, they cause a host of health problems. Crossbite affects the way your teeth look and this can eat into your confidence because crossbite affected teeth don’t look all too good. Beyond the aesthetics, crossbite causes problems with jaw grinding, causes gum recession, loss of teeth and temporom andi bular joint problems. These are problems which get worse by day and if they go for too long without treatment, they cause painful pressure on the neck, head and on the jaw. It is not surprising therefore that people with crossbite problems complain about headaches, pain in the neck and difficulties chewing. With time, the crossbite will affect the jawline and the way the face pans out. It is therefore important to seek early medical treatment as soon as you detect crossbite.

Early detection of crossbite

Owing to the ramifications associated with crossbite, it is important to try and detect its presence as soon as possible and try to correct it as soon as you can. It is easy to identify crossbite especially at a young age because the symptoms and signs are clear. If the teeth don’t align properly when you bite down, then you should be worried and should visit your dentist for further checks. If crossbite is detected, there are very many treatment options that can be used to correct the crossbite and help you attain the normal dental orientation.

Crossbite correction and treatment options

There are very many treatment and correction options available when it comes to treating crossbite problems. Most of these treatment options are however effective when they are used at early age when the teeth have not developed fully and can be moved with ease. This does not mean that there are not treatment options for adults. There are adult options as well the earlier the crossbite is treated, the better. The most common forms of treatment include;

Maxillary expander

Here a palatal expander is used to widen the upper jaw or the maxilla so that the upper jaw and the lower jaw can fit perfectly together. The metal expander is installed in the upper jaw and is permanent for a limited period of time extending up to a year. They are very effective especially in adults.

Removable expanders

Removable expanders are similar to maxillary expanders only that they can be removed. They are used when the crossbite is not as severe. They are best suited for children whose crossbite is only getting started.


These are the most commonly used corrective devices used to correct crossbite and are ideal for both children and adults. Braces are used to align teeth into position by applying the required pressure to push them back and align the bottom and upper teeth.


In extreme cases, surgery is used to correct crossbite. This is in instances where braces and expanders or a combination of both is unable to effectively correct the crossbite.
