Orthodontic treatment for children typically falls into two phases: interceptive treatment, which addresses developing problems early, and comprehensive treatment, which corrects alignment once most permanent teeth have come in. Understanding the difference helps parents make informed decisions about when to start care and what to expect at each stage. At Kennedy Dental Care, our orthodontist Dr. Timothy Kuhlman provides both phases of treatment for children and teens across our Corpus Christi locations.
Interceptive treatment (also called Phase I) is recommended for children around age 7, when the front permanent teeth begin to erupt. It focuses on correcting issues that respond better to early intervention, such as underbites, crossbites, and severe crowding. Treating these problems before age 10 typically produces better outcomes and can reduce the complexity of later treatment.
Comprehensive treatment (Phase II) begins once most or all permanent teeth have erupted, typically between ages 10 and 14. It addresses overall alignment, bite function, and aesthetics. Depending on the case, comprehensive treatment can be completed with traditional braces or clear aligners.
Early / Interceptive/ Phase I Treatment
Seeks to correct:
Anterior crossbite/underbite (“Bulldog”)
Posterior crossbite, especially with asymmetry
Habits (thumb sucking, tongue thrust swallow)
Impacted front teeth
Severe crowding overlapping of permanent teeth
Flared/spaced front teeth (risk f trauma without treatment)
Why early treatment
Underbites respond better when treated before age 10
Posterior crossbites can lead to (asymmetry and restrict airway)
Habits are harder to break the longer they continue
Decrease the risk of trauma to protruded front teeth
Increased self-esteem
Risks of early treatment
Types of early treatment
Expanders (with facemask if underbite present)
Habit-breaking appliances)
Braces (usually limited to permanent teeth)
Clear aligners (excellent for severe spacing or crowding)
Retainers with quarterly eruption checks upon completion
Limited / Esthetic Treatment
Addresses mild concerns, (orthodontic relapse, anterior concerns)
May involve compromised treatment/bite
Treatment time is approximately 6-12 months
Can be done with braces (metal and/or ceramic/clear.
Retainers will be fabricated to maintain alignment
Once Phase I treatment is complete, most patients enter a monitoring period where the remaining permanent teeth are checked quarterly as they erupt. When the time is right, comprehensive treatment begins to finalize alignment and bite correction across all teeth.
Comprehensive / Phase II Treatment
Can begin upon eruption of all or most of the permanent teeth
Ages 10 to 99
Younger patients more tolerant of treatment than older ones
Severe overbites are best treated in adolescence (11 – 14 yes.)
Can utilize growth to help the bite
Goal is to improve esthetics and function
Severe cases may require jaw surgery
Can be done with braces (metal end /or ceramic/clear) or clear aligners
Advantages of Braces

Advantages of Aligners
Disadvantages of Aligners
100% Patient Compliance
Can’t’ be used for impaction
Limitations with difficulty

The best time to have your child evaluated is around age 7, even if no treatment is needed right away. Early evaluation gives Dr. Kuhlman the opportunity to monitor your child's development and plan ahead if interceptive care becomes necessary. Book an orthodontic consultation at Kennedy Dental Care's Saratoga or Calallen location to get started.
