Phase I is most effective at correcting underbites, poor oral habits, and narrow upper arches. In some cases, Phase I is effective at correcting crossbites as well. Recent research has shown overbites do not respond as well to Phase I treatment.
When you visit our offices we will have a frank discussion with you about whether or not Phase I is likely to help your child. We would never recommend Phase I if there is not a clear and present benefit for your child’s oral health.
