The service at Washington Orthodontics is exceptional, if you are looking for someone to truly take care of your perfect smile that you have been yearning for- this is the place! From the front desk- Erika Vargas to Dr. Sung and all the support! I just finished my treatment and am beyond satisfied with the results. If I ever had doubts or questions they answered them and took me in multiple times a week to make sure I was happy with my progress. I can’t recommend this place enough, I have brought in friends, family and now my husband. Thank you for the quality of care.

We’ve been really happy with Dr Sung and his team. They’re always super friendly, flexible, personable and very professional! We’ve had 2 treatments with Washington Orthodontics (one for a cross bite, and the other for braces). On both occasions we’ve been extremely happy and have no hesitations in recommending them.

Why Choose Us

Selecting your orthodontist in Federal Way, WA, is an important decision that affects both your health and confidence. Our practice stands out through personalized orthodontic care, cutting-edge technology, and a patient-first approach that puts your needs at the center of every treatment plan.

FAQs About Washington Orthodontics

Here are answers to common questions about choosing orthodontics and what to expect from your orthodontic experience.

What makes Washington Orthodontics different from other dental offices?

Washington Orthodontics, a trusted orthodontist in Federal Way, WA, specializes exclusively in orthodontic care—meaning Dr. Moon focuses solely on straightening teeth and correcting bite problems. This specialized focus, combined with his board certification, ensures you receive expert treatment from someone who has dedicated their career to this specific field. The practice also limits patient volume to maintain personalized attention rather than maximizing appointments.

Do you accept my dental insurance?

We accept most private dental insurance plans and will verify your orthodontic benefits before treatment begins. Our knowledgeable staff will help you understand your coverage, including any deductibles, co-payments, or annual maximums. We’ll submit claims on your behalf and work with your insurance company to maximize your benefits, making orthodontic treatment as affordable as possible for your family.

Can adults benefit from orthodontic treatment?

Absolutely! Orthodontic treatment isn’t just for teens — more adults than ever are choosing to improve their smiles. There’s truly no age limit when it comes to achieving a healthier, more confident smile. Adult teeth can be moved just as effectively as younger teeth, though treatment may take slightly longer due to denser bone structure. We offer discreet options like clear aligners and ceramic braces that fit seamlessly into professional lifestyles, allowing you to straighten your teeth without anyone noticing.

What payment options are available if I don't have insurance?

We offer flexible financing through CareCredit and Cherry, allowing you to spread the cost of treatment over manageable monthly payments. Families who pay in full receive an in-house discount, and we extend special pricing when multiple family members undergo treatment simultaneously. Our goal is to make quality orthodontic care accessible regardless of your insurance situation.

How soon should I schedule a consultation?

The American Association of Orthodontists recommends that children receive their first orthodontic evaluation by age seven, even if all permanent teeth haven’t erupted yet. Adults can schedule a consultation whenever they’re ready to address their concerns. Early consultations allow us to monitor development and intervene at the most opportune time, potentially preventing more serious issues from developing.
