Early treatment begins before the eruption of all the permanent teeth; generally between the ages of 7 and 10. It includes the use of expanders or partial braces. During this phase of treatment, Dr. Hansen can correct crossbites, overbites, underbites, or harmful oral habits, and create space for developing teeth. Standard (full braces) treatment is initiated when all the permanent teeth develop. This generally occurs between the ages of 11 and 13. Comprehensive treatment consists of both early and standard treatment. It provides the optimum results of both phases of treatment in one step.
