What are Phase I and Phase II treatments?

Phase I treatment, or early interceptive treatment, is a limited orthodontic treatment (that comprises expander or partial braces) that is administered before all the permanent teeth have erupted. Typically, this treatment occurs between the ages of six and ten. This treatment is recommended to ensure that more space is available developing teeth, to correct cross bites, under bites, overbites, and or habits that are harmful to oral health. Phase II treatment is more comprehensive as it requires the use of full braces after the permanent teeth have erupted. This treatment typically takes place between the ages of eleven and thirteen.
