Routine Dental Care That's Anything But Ordinary

At Cascadia Smiles, we invite you to visit us at least twice a year for a checkup and routine care. Regular dental exams are vital for preventing, diagnosing, and solving common dental problems and perfecting your smile. It’s also our chance to spoil you with a personalized dental experience — your smile deserves it!

For your benefit, Dr. Osafi and his team offer a complete set of general dentistry services to help you…

  • Improve and maintain excellent dental health

  • Identify small problems before they become large ones

  • Feel confident in your beautiful smile

People often initially chose us as their general dentist for our excellent reviews and beautiful spa-like environment, but what keeps our patients coming back is our consistent relationship-driven care and high-end results.

We approach every appointment as an opportunity to better understand your dental goals and concerns. Working together, we can make a positive difference in your smile, dental health, and overall well-being.

Whatever general dental treatment you require, you’ll be taken care of at Cascadia Smiles.

Did you know?
An estimated 100 million people have silver (amalgam) fillings! Silver fillings are bright and noticeable every time you open your mouth, laugh, or even speak. Conversely, white fillings are created with a similar color and texture to match your natural teeth and be nearly invisible!


Biological Dentistry

We provide biocompatible materials, and implement safe mercury removal and dental ozone as a therapy for certain dental treatments.


Following a broken tooth, root canal, or extensive decay, a crown or bridge may be needed. We take digital impressions, which are more accurate and faster.


Many options including mini implant dentures, Fountain of Youth dentures, and full/partial dentures.

Dental Extractions

Teeth that can no longer be restored will require an extraction and an implant will be placed to preserve the bone and give you that beautiful smile you've been waiting for.

Sleep Apnea Treatment

Do you snore? We can help. Get the healthy restful sleep you need to live your best life.
