All the family can benefit from quality orthodontics in our office. Dr. Teng specializes in the early start, braces, and Invisalign®.

‘‘Before beginning my orthodontic treatment, I felt nervous and very intimidated about smiling, but that has changed and I’m now confident during the day. He put into perspective what would be best for me both in terms of oral health and cosmetically, taking time to explain each step. I am very grateful and would recommend his service to clients of all ages! ’’

- Xuechen F.

‘‘When I first visited them, his team examined my teeth and patiently answered all my questions and concerns. Then, he gave me a very professional and honest advice on each possible treatment method and its pros and cons. His staff is very helpful and friendly, and speaks Chinese and English, which is a plus.’’

- Angelina

‘‘I took my 8-year-old (who already lost 15 baby teeth!) to three orthodontists for evaluation and decided to get treatment at Dr. Teng’s office. He’s knowledgeable and professional. He’s also involved in community events and donates to various community and education-related causes, such as our elementary school’s auction and Bellevue’s Thunderbird Little League. ’’

- Aileen W.

‘‘Dr. Teng assessed and treated me with Invisalign braces. As an adult completing orthodontic treatment, I was anxious, but Dr. Teng was wonderful to work with. His office manager, Jai is absolutely the best! She is exceptionally competent and exceedingly kind. I would recommend this office to anyone who is in need of orthodontic work.’’

Platinum Provider

Enjoy straighter teeth with no wires, no metal, and no compromise.

Dr. Teng is an Invisalign® Platinum Provider for Seattle and Bellevue, WA, with more than a thousand successful treatments.

Clear aligners are one of the best ways for busy adults and image-conscious teens to straighten teeth.

While Invisalign® offers similar benefits to braces, the clear aligners are metal-free and provide more comfort, confidence, and flexibility. For some patients, Invisalign® is more efficient and preferred than braces.
