The best time for kids to have an evaluation with an orthodontist is at age 7. Not all kids would benefit from two phases of treatment but when they do Phase I can dramatically change the trajectory of future orthodontic treatment.
Phase I treatment usually occurs during the mixed dentition when kids have both permanent and primary “baby” teeth. Rather than thinking of Phase I as “early” treatment for kids, we recommend this treatment when it’s “right on time.” Phase I treatment allows for the use of auxiliary orthopedic appliances, such as palatal expanders, to intercept bite or growth problems that may not be able to be easily treated in the future. This treatment can allow for the creation of space to avoid future extractions of teeth.
Phase I can also treat deep bites, open bites, cross bites, underbites, and asymmetries to avoid the need for surgery in the future.
Phase I treatment has the potential to improve kids’ confidence as they head into middle school by closing spaces and reducing flared teeth.
