What is Phase 1 treatment?
Phase 1 orthodontic treatment is typically completed between the ages of 5 and 12. The purpose of this treatment is to establish a strong foundation with a sufficient amount of space for permanent teeth to emerge in alignment.
If your child’s palate (upper arch) is too narrow, this will be apparent during this time. The palatal expander appliance is often used during phase 1 to widen the upper jaw, creating enough space for all permanent teeth to fit in the mouth without crowding or overlapping.
If your child has a severe “underbite” (the lower teeth being ahead of the upper teeth), orthopedic correction of this problem with the use of a face mask is most effective at this stage.
