Types and Causes of Crossbite
- Anterior crossbite
- Posterior crossbite
- Unilateral crossbite
- Bilateral crossbite
- Dental crossbite
- Genetic factors
- Abnormal jaw growth
- Thumb sucking or pacifier use
- Mouth breathing
- Premature loss of baby teeth

Effects of Crossbite
- Uneven wear on teeth
- Increased risk of tooth decay and gum disease
- Temporomandibular joint (TMJ) disorders

- Facial asymmetry

Diagnosis and Treatment of Crossbite

Prevention of Crossbite

- Early orthodontic intervention
- Addressing mouth breathing or allergies
- Using orthodontic appliances as recommended by the dentist

Connections with TMD
- Unilateral posterior crossbite involving a narrow maxillary dental arch
- Functional mandibular shift leading to structural asymmetries if left untreated
- Lower midline deviation, class 2 subdivision relationships, and temporomandibular disorders in unilateral crossbites
- Diagnosis and treatment using a deprogramming splint
- Early treatment to prevent temporomandibular joint pathology

Crossbite (Wikipedia)

Crossbite is a form of malocclusion where a tooth (or teeth) has a more buccal or lingual position (that is, the tooth is either closer to the cheek or to the tongue) than its corresponding antagonist tooth in the upper or lower dental arch. In other words, crossbite is a lateral misalignment of the dental arches.
