Phase I Treatment
Early, preventive treatment started around age 8 to 9 to:
improve eruption of rest of permanent teeth,
manage space problems--crowding or spacing,
improve appearance, function, even speech,
give confidence in formative years,
decrease the duration of phase II (full braces) later.
Phase I does not prevent the need for phase II (full braces) later when all baby teeth are gone, around age 12. However, it does shorten the length of full braces.
It is not doing braces over twice. It does not cost double. Although it does cost a little more overall, a significant discount is given in phase II, because of shorter duration.
Not every child needs phase I--only for those who need treatment that cannot wait until age 12.
