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
- First consult around age 7 (front permanent teeth erupting)
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
- Damage to the teeth with poor oral hygiene
- Possibility of future treatment once remaining teeth erupt
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
- Familiarity with braces
- Less patient responsibility
- Can treat all cases
Disadvantages of Braces
- Potential Breakage/Pokey wire
- Hygiene difficulties
- Food Restrictions
Advantages of Aligners
- Esthetics/Hygiene
- Less Frequent Appointments
- Comfort
- Less Restrictive Diet
Disadvantages of Aligners
- 100% Patient Compliance
- Can’t’ be used for impaction
- Limitations with difficulty
- Retainers will be fabricated to maintain alignment
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.
