Phase 1 orthodontic treatment, or interceptive orthodontics, typically occurs between 6 and 9 years of age when patients begin to lose their baby teeth. The American Association of Orthodontists recommends that all children get a checkup with an orthodontist no later than 7 years old. This is the best time to detect whether there are disturbances in jaw growth or tooth development that are more easily addressed at this age. With Phase 1 orthodontics, we can stop future problems before they even start.
A short phase of orthodontics can be utilized at this time to favorably enhance the growth of your child’s jaw. We may also use orthodontic treatment to create space to guide the development and eruption of the permanent teeth into proper alignment. This phase of treatment typically lasts from nine to 12 months, and although treatment is individualized for each patient, common orthodontic therapies used at this time include:
- Headgear
- Limited phase of braces (selected teeth)
- Specialized retainers
- Expansion appliances
- Space maintainers
Phase 1 focuses on the growth and development of teeth and the jaw. The goal is not necessarily to align the teeth at this point. Most patients need a full set of braces/Invisalign once all of the permanent teeth come in, which is referred to as Phase 2. Patients generally begin phase 2 of orthodontic treatment during early adolescent or adolescent years.
