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
- Speech difficulties
- Facial asymmetry
Diagnosis and Treatment of Crossbite
- Clinical examination by an orthodontist
- Dental impressions and X-rays
- Palatal expanders
- Braces or clear aligners
- Orthognathic surgery
Prevention of Crossbite
- Encouraging proper oral habits in children
- Regular dental check-ups
- 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 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.
