Orthodontic treatment for children

When is the best time for a consultation?

The American Association of Orthodontists recommends an initial consultation with an orthodontist at the age of 7. It is always preferable to schedule a consultation sooner than later, as it can mean the difference between an effective treatment and a long, complicated and expensive treatment.

Orthodontic treatment phases

Orthodontic treatment can be carried out in a single comprehensive treatment phase or divided into two separate treatment phases with a maintenance phase between the two. The number of phases and duration of treatment depend on several factors and are therefore not the same for all patients. When an initial treatment phase is necessary, it usually takes place around 7-9 years of age and aims to correct specific problems using various types of devices.

When is the best time to start treatment?

Orthodontic treatment may be initiated for specific dental problems before all permanent teeth have erupted in the mouth. Early treatment, which is usually initiated after the eruption of the four upper (front teeth) and lower incisors has completed (around 7-9 years of age), is recommended when one of the problems illustrated on this page is present.


Overjet The upper anterior teeth are too protruded compared to the lower teeth


Anterior crossbite The lower anterior teeth are too protruded compared to the upper teeth


Deep bite The upper anterior teeth cover the lower front teeth too much


Open bite Space between the upper and lower anterior teeth even when the back teeth are touching.


Crowding The upper and/or lower teeth overlap.


Posterior crossbite The lower posterior teeth protrude out more than the upper posterior teeth.


Centre line deviation The centre lines of the upper and lower arch do not coincide.


Diastema Presence of spaces between the upper and/or lower teeth.

Advantages of early treatment

  • Protect protruding anterior teeth from accidents by repositioning them backwards.
  • Improve the link between both jaws, allowing better development.
  • Take maximum advantage of growth to improve the success of treatment.
  • Improve facial appearance and self-esteem.
  • Take advantage of good cooperation of the patient at this age.
  • Potentially avoid or minimize the need for further treatment when the patient is older.
