Orthodontic treatment for children is also known as interceptive orthodontics. It is commonly referred to as Early or Phase 1 treatment. Early intervention takes advantage of the fact that a child’s jaws are still growing and malleable. A children’s dentist will often refer to an orthodontist for evaluation when dental crowding or a crossbite is present. The orthodontic specialist may wish to widen the dental arch to make room for adult teeth or correct a crossbite. The probability of dental impaction increases when there isn’t enough room for the adult teeth to emerge. Permanent teeth erupt into better positions when they have sufficient room to come in. Palatal expansion with or without a traditional palatal expander can be used to create the additional space needed.
