Early (interceptive) orthodontics explained
6 August 2026 · 5 min read
Interceptive treatment uses your child's growth as a tool. Learn what phase-one orthodontics can and cannot achieve.

What interceptive treatment means
Interceptive or phase-one orthodontics happens while baby and permanent teeth are both present, usually between ages six and ten. Instead of straightening every tooth, it corrects the underlying problem: a narrow jaw, a crossbite, a habit, or a lack of space.
Common phase-one goals
Typical goals are widening a narrow upper jaw, correcting a crossbite or underbite, creating room for crowded permanent teeth, protecting protruding front teeth from trauma, and stopping habits such as thumb sucking or tongue thrust.
Does it replace braces later?
Sometimes yes, often no. Phase one creates a healthier foundation; a shorter phase two with braces or aligners may still be needed to fine-tune alignment once all permanent teeth have erupted. The trade-off is usually a simpler, faster and more stable overall result.
