- At the front (anterior crossbite).
Each type affects growth differently. maxillary and the jaw, Therefore, it requires a specialized assessment.
2. Types of crossbite
- Unilateral posterior crossbite: One side bites "upside down".
- Bilateral posterior crossbite: Both sides bite from the inside.
- Anterior crossbite: The upper teeth are behind the lower teeth.
3. Most frequent causes
A crossbite can be due to one or more causes:
- Lack of growth of maxilla
- Oral habits (thumb sucking, prolonged pacifier use, chewing)
- Mouth breathing or functional breathing problems

Many of these factors can be corrected if they are detected early.
