Hello,
This is being a genetic disorder offers an explanation of why she may have certain dental conditions. This makes treatment more difficult and involved. If she has missing teeth, extra teeth, undersized teeth, delayed eruption, an overbite or underbite, these conditions are best treated by an orthodontist. A child has the advantage of the jaw growing and offers the opportunity to guide jaw growth as well as tooth position. As an adult, surgery would have to be considered to realign the jaw if severe overbite or underbite is present. Definitely consider an orthodontic evaluation. Multiple opinions are recommended for involved treatment. Consider visiting a dental school where many specialists and resources are available. Considering this to be a rare genetic condition, you may have a difficult time finding doctors with previous exposure to this disorder.
Poor enamel formation, defects and notching may require restorative treatment prior to orthodontics. Bonding or crowns may need to be placed. If teeth are too weak or not suitable for movement, then consideration for other options such as implants, bridges or dentures need to be considered. Sometimes a temporary stage of tooth replacement is necessary.
The assistance of other specialist such as an oral surgeon and periodontist most likely should be considered. Often multiple specialist work together. Your general dentist coordinates and communicates between all specialist. Shape of her palate, quality and quantity of her gums and any growths such as papillomas may affect treatment considerations.
You will have a greater challenge, but with coordinated care ther will be options to improve your daughter's smile. Thank you for your inquiry. Please consider providing additional details and I will be glad to offer suggestions.

Hello,
Thanks for your query.
Regular surveillance, with frequency increased as needed during and after adolescence, facilitates early detection of anomalies and timely preventative and/or corrective treatment planning in focal dermal hypoplasia (FDH) patients.
Medical management is targeted toward the various soft-tissue, dental and skeletal anomalies, with the goal of achieving optimal functional and aesthetic results. Treatment with a flashlamp-pumped pulse dye laser may ameliorate the pruritic symptoms that sometimes are noted in affected skin, and it may improve the clinical appearance of the telangiectatic and erythematous skin lesions.
I do hope that you have found something helpful and I will be glad to answer any further query.
Take care
