The Canadian Association of Orthodontists recommends that kids should be seen for their first orthodontic checkup around the age of 7. By this age, the teeth have developed enough to determine if any problems are arising with the alignment of the permanent teeth.
In some cases, patients may benefit from early treatment that starts before all the baby teeth have fallen out. Many orthodontic problems are easier to correct if detected early rather than waiting until jaw growth has slowed. Early treatment may mean a patient will avoid more complicated treatment later in life.
