Common Questions From Our Patients

If I don’t have insurance, can I still receive care?

Of course you can! Dr. Koo designed an in-house savings program to provide affordable dental care whether you have insurance coverage or not. Your annual membership benefits include two teeth cleanings, two complete dental exams, and a full set of X-rays; one emergency exam as needed, including an X-ray focusing on a particular area of concern; and discounts of 10-15 percent on our other services. You can also opt for a semi-annual membership, which includes all of these special offers with the exception of one dental cleaning and exam.

What if I can’t make a weekday appointment?

We know our patients are often busy during the week, so we’re open the first, second, and third Saturdays of every month from 8 a.m. to 2 p.m. We’re also available after hours and on weekends for emergencies. If you have an urgent dental need outside of our normal office hours, call our emergency number at 425-954-5374. For other questions or to make an appointment, call our regular number at 206-922-4573. We’re here to help!

What are dental implants and how can they help me?

Dental implants are small titanium posts that are placed in your jaw where you have missing teeth. They serve as replacement teeth roots and will support artificial teeth once they’re fused with your bone. Implants will help you get back your beautiful smile and allow you to eat all your favorite foods again. Plus, they help prevent jawbone deterioration, which is common when you are missing teeth.
