Should i start to do an orthodontic appliance to my 9 years old girl .. she has proclined anterior central incisor after removing two suppernumeraries?

An orthodontist: Would be best suited to evaluate for the need for orthodontic intervention. Most likely this will be prescribed. Depending on her level of maturity and compliance, she could quite possibly qualify for invisalign teen aligner treatment.

Individual consult: It is important that your daughter be evaluated by an orthodontist. It could be that not much will be gained by early or interceptive treatment. I tend to do less early intervention than when i was younger, as I have found the best criteria for treatment is: is there something you can do now which you cannot do later, or with much less invasiveness. Invisalign is totally inappropriate (root tq).

Ask: Ask an orthodontist. Don't fixate on just your child's protrusion. Have her evaluated by a qualified orthodontic specialist who will evaluate her entire occlusion and dent-facial relationships and advise you on the best course of treatment, including ideal timing, for your daughter. Don't wait, go now.

Yes: It would be ideal to at least have your daughter evaluated by an orthodontist. At age 9 and having supernumerary teeth removed, she might be at an ideal time to have an early course of orthodontic treatment. Even if that doesn't complete all the required movement it would make the final phase of orthodontics less complicated and quicker. Good luck!

May wait: It is usually best to wait for a full complement of permanet teeth prior to orthodontics. But, there are a few exceptions. Talk to an orthodontist certified by the american board of orthodontics.

Proclined: Esthetics are a very subjective thing. However it is very common to "phase" orthodontic treatment, correcting little bit now and more later. Discuss the pros and cons with your orthodontist to get the best course of treatment for your child.
