Key Takeaways
- Crossbites are misalignments where the upper teeth sit inside the lower teeth and can be classified by origin, extent, and location.
- There are three main crossbite types based on origin: dental, skeletal, and functional, each requiring different treatment approaches.
- Dental crossbite is caused by mispositioned teeth, often due to habits like thumb sucking or crowded teeth, and can lead to tooth wear, gum disease, and tooth decay.
- Skeletal crossbite involves jawbone discrepancies, often hereditary, causing facial asymmetry and requiring more complex treatments such as jaw surgery.
- Functional crossbite results from bite interference causing jaw shifting and can contribute to temporomandibular joint disorder and jaw pain.
- Crossbites vary in extent from single tooth to unilateral and bilateral crossbites, affecting one or both sides of the mouth.
- Location-based crossbites include anterior (front teeth) and posterior (back teeth) crossbites, with posterior crossbites further divided into lingual and buccal types.
- Early diagnosis and treatment, including braces, Invisalign aligners, palate expanders, or surgery, are crucial to prevent complications like jaw misalignment, loose teeth, and tooth wear.
- Untreated crossbites can lead to oral health issues such as gum disease, tooth decay, jaw pain, and overall misaligned bite affecting chewing and speech.
- Consulting a dental professional and considering dental insurance options can help manage treatment costs and ensure proper crossbite correction for long-term oral health.
Types of Crossbites Based on Origin
Crossbites can be broadly categorized based on their origin: dental, skeletal, and functional. Each of these categories has unique characteristics and underlying causes, impacting the approach to crossbite treatment.
Dental Crossbite
Dental crossbite occurs when the the upper teeth sit inside the lower teeth vs over them. This type of crossbite primarily results from the malposition of the teeth rather than an issue with the jawbones. Factors such as undue pressure from surrounding teeth or external forces, like thumb sucking or prolonged use of a pacifier, can lead to this type of misalignment. Crowded teeth further exacerbate this condition, leading to a higher risk of developing a dental crossbite.

The implications of a dental crossbite can extend beyond mere aesthetics. It can lead to issues such as teeth grinding, gum disease, tooth decay, due to improper cleaning that can affect teeth and gums.
There are various crossbite treatment options available to address this type of crossbite malocclusion. Orthodontic treatments like traditional braces or Invisalign aligners and palatal expanders are common methods to correct a dental crossbite. In severe cases, crossbite surgery might be necessary to achieve proper alignment and alleviate symptoms.
Skeletal Crossbite
Skeletal crossbite is a more complex condition, rooted in the structural discrepancies between the upper and lower jaws. This type of crossbite occurs when the upper jaw is smaller or positioned differently than the lower jaw, leading to a misalignment of the teeth. These discrepancies are often hereditary or result from growth factors, making skeletal crossbite a challenging condition to address.

The inadequate development of the upper jaw causes the upper teeth sit inside the lower teeth, creating a misalignment. This condition often results in functional and aesthetic issues, such as facial asymmetry, asymmetrical jaw growth, and difficulty chewing, affecting both the upper and lower teeth, and the upper or lower jaw.
Treatment typically involves orthodontic appliances or, in more severe cases, jaw surgery or orthognathic surgery to correct the jaw alignment and achieve a balanced bite.
Functional Crossbite
Functional crossbite arises when there is interference in the bite that forces the lower jaw to shift to achieve a comfortable closure. This type of crossbite is not caused by misalignment of the teeth or jawbones but rather by how the teeth come together during biting.

Such interference can lead to a misaligned bite and discomfort, necessitating intervention for the temporomandibular joint disorder to restore proper jaw bone function and address teeth misalignment, jaw misalignment, and jaw shifting.
Types of Crossbites Based on Location
Crossbites can also be classified based on their location in the mouth, namely anterior and posterior crossbites. Understanding differences between these types of crossbite is crucial for determining the appropriate crossbite treatment.
Anterior Crossbite
Anterior crossbite refers to when the upper front teeth are positioned behind the lower front teeth. This condition can be caused by discrepancies in the size or position of the jaws, or by the misalignment of individual teeth. The aesthetic impact of an anterior crossbite is significant, often affecting the patient’s confidence and appearance.

Additionally, anterior crossbites can cause functional issues such as difficulty in biting, chewing, and even speech impediments. Crossbite correction with orthodontic treatments like braces or palatal expanders can help correct this misalignment and prevent further complications.
Posterior Crossbite
Posterior crossbite affects the alignment of the back teeth, leading to a misalignment where the upper jaw is either narrower than the lower jaw, or much wider. This condition can arise from narrow dental arches, skeletal discrepancies, or a combination of both.

A posterior crossbite can lead to dental and jaw misalignments. If left untreated, it can cause significant discomfort and functional issues. Orthodontic treatment options such as palate expanders or braces can help correct this condition, ensuring proper alignment of the back teeth and relieving any associated jaw pain or discomfort.
Types of Posterior Crossbite
Posterior crossbites can be further classified into specific types of crossbite such as lingual and buccal crossbites. These classifications depend on the exact alignment of the back teeth and the direction in which they are misaligned, inward or outward towards tongue.
Posterior Lingual Crossbite
Lingual crossbite occurs when the lower back teeth are positioned outside the upper back teeth, causing them to occlude on the outer side of the upper back teeth. This misalignment leads to significant discomfort and potential dental issues.
Read more…
Addressing a lingual crossbite often involves orthodontic treatments to reposition the teeth appropriately and alleviate any associated pain.
Posterior Buccal Crossbite
In a proper bite all upper teeth bite on opposing lower teeth. In a buccal crossbite, also known as a Brodie bite, upper back teeth extend over the bottom teeth and don’t bite on them. This type of misalignment can cause significant discomfort and issues with chewing and overall oral function. Read more…
Braces or expander are commonly used to correct a buccal crossbite, ensuring proper alignment of the back teeth and restoring normal bite function. Early diagnosis and treatment are essential for preventing long-term dental issues.

Crossbite Types Based on Extent
Crossbite can vary in severity, ranging from mild type of crossbite to moderate and severe crossbite. The extent of the crossbite often determines the complexity of treatment required. Mild to moderate crossbites may involve a single tooth or a few teeth. Moderate to severe crossbites often affect multiple teeth, sometimes on one side (unilateral crossbite) or both sides of the mouth (bilateral), and may involve more significant misalignment of the upper and lower jaws. Traditional braces and Invisalign aligners are a viable treatment options for many crossbite issues. Severe cases can lead to complications like jaw pain, wear of occlusion, and gum disease, often necessitating more comprehensive interventions including palate expanders or even jaw surgery to achieve proper crossbite correction and restore dental health.
Single Tooth Crossbite
A single tooth crossbite affects just one tooth, either in the front or back of the mouth. This condition occurs if an adult tooth fails to erupt properly after baby tooth came out, leading to misalignment of the adult teeth.
Correcting a single tooth crossbite typically involves orthodontic treatment and crossbite correction to fix a crossbite and restore proper alignment.
Unilateral crossbite
Unilateral crossbite affects only one side of the mouth, while bilateral crossbite involves malocclusion on both sides of the mouth.
Bilateral Crossbite
Bilateral crossbite refers to a condition where the crossbite is observed on both sides of the mouth. This means that the upper teeth sit inside the lower teeth on both the left and right sides. This type of crossbite can affect multiple teeth and often involves both the posterior and anterior teeth.
Bilateral crossbite often develops during the transition from primary teeth to permanent teeth, making early diagnosis and intervention with orthodontic treatment critical.
Summary
Understanding the various types of crossbite malocclusion, their causes, and treatment options is essential to achieve optimal dental health. From dental to skeletal and functional crossbites, each type presents unique challenges and requires specific interventions.
Ultimately, early diagnosis and appropriate treatment are crucial for preventing long-term dental issues and ensuring a healthy, functional bite. If you suspect a crossbite or experience related symptoms, seek professional help to explore the best treatment options for your specific condition.
