Phase I Treatment

Airway Orthodontics

Airway orthodontics is not just about straightening the teeth, it also focuses on healthy breathing and proper jaw development. Our expert orthodontists examine the teeth, jaws, and airway, and assess how well they work together. This approach helps them identify any issues that may cause mouth breathing, snoring, and sleep disturbances. With early treatment and personalized treatments, we create space for your tongue and airway.

Our custom treatment plans improve airflow while straightening the teeth and making the jaw more balanced. Airway orthodontics is an effective treatment that can be beneficial for both children and adults. We address the root causes and help our patients achieve a healthier and more beautiful smile.

Holistic Pediatric Orthodontics for Growing Smiles

We believe pediatric orthodontics must support your child’s overall health. Our holistic approach examines the important connection between oral development and the entire body, considering how nutrition, breathing, and sleep affect your child’s growing smile.

Instead of just addressing problems as they appear, we aim to find the root cause of dental issues. For example, how narrow arches or tongue posture can influence a child’s airway and sleep quality.

Biocompatible materials and minimally invasive procedures will make sure that every treatment supports your child’s natural growth and long-term health. As an experienced orthodontist serving Tarzana, CA, we can often help develop the teeth and bones normally, which means you don’t need more invasive treatments later on.

Our goal is to make the dental office a safe and happy place for kids to feel confident and safe, so they can have a good experience with dental visits.
