What is a Crossbite?

Have you ever noticed that your teeth don’t fit together quite right when you bite down? Perhaps you experience discomfort or difficulty when chewing certain foods. If so, you might be dealing with a dental condition known as a crossbite. While it may sound intimidating, crossbites are relatively common and treatable. In this blog, we’ll dive into the world of crossbites, exploring what they are, how they develop, the potential consequences of leaving them untreated, and the various treatment options available to restore your smile’s harmony.

In simple terms, a crossbite occurs when there’s a misalignment in the way your upper and lower teeth fit together when biting down. Normally, the upper teeth should slightly overlap the lower teeth, creating a harmonious bite. However, in cases of a crossbite, the opposite happens – the upper teeth sit inside the lower teeth, or they may not meet at all. This misalignment can affect one or multiple teeth, and it can occur on either side of the mouth.

Types of Crossbites

Crossbites can be classified into two main types: anterior and posterior crossbites.

  • Anterior Crossbite: This type of crossbite affects the front teeth. When you bite down, the upper front teeth will be positioned behind the lower front teeth, leading to an abnormal bite pattern.
  • Posterior Crossbite: In this case, the problem lies in the back teeth. The upper molars fit inside the lower molars when biting, causing a disruption in the normal alignment.


What Causes Crossbites?

Several factors can contribute to the development of crossbites, including genetics, dental habits, and the growth of the jaw. For some individuals, a crossbite may be hereditary, passed down from one generation to another. Prolonged use of pacifiers, thumb-sucking, or other oral habits during childhood can also lead to crossbite issues as they influence the growth and alignment of the teeth.

Moreover, abnormal jaw growth or a narrow upper jaw can create insufficient space for the teeth to align correctly, resulting in a crossbite. If left unaddressed, this condition can worsen over time and cause potential dental and skeletal issues.

The Consequences of Untreated Crossbite

Aside from the aesthetic concerns, untreated crossbites can lead to various health issues. The misalignment of the teeth can cause uneven wear, leading to premature tooth deterioration and enamel erosion. Chewing difficulties may also arise, as the improper bite can put excessive pressure on certain teeth, causing discomfort and pain.

Moreover, crossbites can contribute to speech problems, such as lisps or difficulty in pronouncing certain sounds. This can potentially impact an individual’s confidence and self-esteem, especially during social interactions.

Treatment Options for Crossbites

Fortunately, there are several effective treatments available to correct crossbites and restore a harmonious bite.

  • Braces: Traditional braces remain one of the most reliable and common methods to correct crossbites. By applying gentle pressure on the teeth over time, braces gradually shift them into their proper positions.
  • Invisalign: For those seeking a more discreet option, Invisalign aligners are an excellent choice. These clear, removable aligners work similarly to braces but offer greater convenience and aesthetics.
  • Palatal Expanders: To address crossbites caused by a narrow upper jaw, a palatal expander can be used. This device widens the upper jaw, creating more space for the teeth to align correctly.
  • Tooth Extraction: In severe cases, when the overcrowding is a significant factor contributing to the crossbite, tooth extraction may be necessary to create sufficient space for realignment.


In conclusion, a crossbite is a dental misalignment that affects the way your upper and lower teeth fit together when biting down. It can be caused by various factors and may lead to dental problems and speech difficulties if left untreated. However, with the multitude of treatment options available, there’s no need to suffer in silence. Hurry and consult with GLOJAS experts today to get your crossbites treated!
