Palatal expanders and airway orthodontics for 5 y.o.

I'm looking for recommendations for airway-focused orthodontists for my 5-year-old daughter. Palate expansion has been recommended as part of her treatment plan.

We've already had consultations with Dr. Ferrari (Kensington), who uses the Schwartz appliance, and Dr. Hockel (Walnut Creek), who works with the Crozat appliance. I'm currently seeking a third opinion and would really appreciate hearing from anyone with experience using these or other types of appliances.

Most importantly, I'm trying to understand the long-term effects and potential risks of these treatments. I'm also curious whether working with a cranial osteopath alongside orthodontic treatment is necessary or beneficial.

If you’ve been through this process with your child or have any insights to share, I’d be very grateful.
