Often, habits such as prolonged thumb sucking, tongue thrusting, and certain swallowing or breathing patterns that can open or distort the bite are best addressed when care begins at a younger age. Interceptive treatment is also helpful when the top jaw is too narrow, not aligned with the lower jaw, or when the top teeth close behind the lower ones. Likewise, if a young child’s front teeth protrude excessively, or very severe crowding is present, a first phase of orthodontic care can be beneficial.
The objectives of interceptive treatment and a first phase of orthodontic care are to influence jaw growth, create more space for crowded teeth, help correct harmful habits, and improve facial aesthetics. With interceptive treatment, the likelihood of impacted permanent teeth, as well as the need for extractions, can be reduced. Interceptive treatment can also simplify the next phase of orthodontic care.
