Dr. Teng is your local orthodontist who believes in taking a comprehensive approach when caring for your family. He doesn’t just straighten teeth but focuses on the harmony of your teeth, bite, jaw joints, and airway to give you the best possible outcomes.

Before opening his office, he practiced TMJ care and continues learning through ongoing education and training. The truth is, Dr. Teng doesn’t just treat teeth – he treats the person behind the smile!

He’s been on both sides of the dental chair and understands what you’re going through. Dr. Teng didn’t like his smile growing up and underwent orthodontic treatment.

Fast forward, he’s helped thousands of people achieve their own improved smiles and looks forward to helping you. Our orthodontist in Seattle and Bellevue wants you to feel confident, comfortable, and proud of your smile. 

Through personalized treatment plans that fit your needs, lifestyle, comfort, and budget, Dr. Teng helps you achieve the best results. He also works with local dentists to ensure a smooth process with braces or Invisalign®.
