A crossbite is one of the types of malocclusionor misaligned teeth. It occurs when your upper front teeth sit inside your lower front teeth or when the upper back teeth and the lower back teeth are too far apart. A crossbite is seen outwardly as an uneven jaw.

Crossbite can be treated in different ways because different factors cause them —the factors that cause crossbite include behavioural factors like thumb sucking or genetic factors like overcrowded teeth.

 

Types Of Crossbite

Crossbite can be classified by how many teeth are affected, where they occur and their position in the mouth.As a result of this, there are various types of crossbite,such as:

Anterior Crossbite

This is also known as an underbite— its occurs where the upper front teeth rest behind the lower front teeth. There are different causes of anterior crossbite; they include:

  • Thumb-sucking: this pressures and pushes the roofof the mouth upward making it narrower rather than wider.
  • Mouth breathing in babies: this makes the tongue not to rest on the top of the mouth, which makes the upper jaw wider.
  • Overcrowded teeth: a crowded lower jaw can make it push further forward than they should, therefor causing a crossbite.
  • Repairs to cleft lips: The development of the upper jaw can be affected after cleft lip surgery, causingcrossbite.

An Anterior can be noticedeasily because it makes the jaw to protrude and appear uneven.

Posterior Crossbite

A posterior crossbite affects the teeth behind the mouth. This type of crossbiteis causedbyfactors such as late growth of milk teeth, permanent teeth growing in the wrong order/position and other factors that affect the front teeth such as thumb sucking and mouth breeding. Treating a posterior crossbite should be done early with an early diagnosis.

Buccal crossbite

A buccal crossbite occurs when teeth are positioned too far out towards the cheek. One of the significant symptoms of buccal crossbite is when you feel your inner teeth bite into the surface of your cheek when your mouth is closed.

Lingual crossbite

A lingual crossbiteoccurs when the teeth are positioned towards the tongue. One primary symptom of this type of crossbiteis when you feel the biting surface of your inner teeth with your tongue when you close your mouth.

Bilateral and unilateralcrossbite

A bilateral crossbiteoccurs when both sides of your mouth are affected by the crossbite while a unilateral crossbiteaffects just one side of your mouth. These two types of crossbite can be treated in the same way. Althoughthe process might be different.

Single Tooth And Segmental Crossbite

A single tooth crossbite affects just one tooth which occurs when your bottom front or canine tooth sticks forward too far while your upper tooth pushes inwards.

A segmental crossbite, on the other hand, is when a few of your teeth do not line up —it affects 2 - 3 teeth in a row, making them stick inward towards the tongue or outward towards the cheek.

Treating ACrossbite With Braces

Posterior and anterior crossbitesare mostly treated with braces. Your orthodontist will discuss the various types of braces with you, that can be used for teeth alignment to help you choose the most suitable treatment for you.

A palate expander is the most common type of braces used for treating crossbite because it helps to widen the upper jaw making the top teeth sit correctly with the lower teeth — it needs regular adjustment to provide the necessary pressure to push the teeth further apart. This type of braces can attain the desired result within a few months because of the rapid expander.

Further teeth straightening may be required after the palate has expanded the jaw to the correct size —other kinds of fixed braces can be further used to straighten your teeth afterwards. Retainers can be used to keep the teeth in their new position once the teeth straightening process with braces has been completed.
