Holistic Dentistry

Treating the mouth as it applies to the whole body and person, not as a separate part. We must think of the real person when treating dental issues.
We are eliminating harmful chemicals discharged to our water system, keeping our water clean and local wildlife happy. We all share our island’s resources.
We strive to reduce single-use products and plastics, lessening our impact on both wildlife and the environment. What we keep out of our landfills can not end up in our oceans and forests.
When we consider our actions and reduce our negative impact on the ecology, we can make a difference for years to come.

What Makes Vashon Dental an Eco-Friendly Dentistry

Single-Use Plastics
We have reduced the use of single-use plastics where possible and continue to make changes to reduce the use of disposable consumables.
Biodegradable Floss
We are supplying biodegradable floss made from cornsilk in refillable glass containers and bamboo toothbrushes as samples.
Non-toxic Disinfectants
We have implemented an environmentally safe and non-toxic disinfectant that is very effective against viruses and bacteria. We produce the disinfectant in-house through the electrolysis of salt water. Hypochlorous acid is known as a natural germ killer. Learn more
As many people do at home, we actively recycle and compost.
Digital X-Rays
Our digital x-ray system requires no chemicals and produces zero (0.00) waste.
Water-free Oral Vaccums
Our dental vacuums are 100% water-free, which means zero water waste. Learn more

As important as our commitment to the environment is, it will never supersede our commitment to protect our patients and staff's health. While we use plastics for minimal sanitary purposes, we continue to research alternatives.


We maintain expectations set by our patients in both the quality and longevity of our treatments and procedures and their safety and well-being. In the past, many dental offices used single-use disposable plastics. We have reduced the number of single-use plastics and switched to biodegradable and reusable products. We think long term with what we provide and the downstream environmental effects of our daily servicing of patients.

  • Ensure mercury-free and metal-free fillings and crowns
  • No use of inferior materials for purposes of internal cost-cutting
  • Reduction of our impact on the environment in all aspects of our practice
Supporting Vashon Ecology
“Being raised in Tacoma, attending the University of Washington and Washington State University has made me aware of the changes seen across our state over the past 40 years. These changes are why I have devoted daily practices targeted at preserving our beautiful region and its residents. Preservation has been our belief and daily routine here at Vashon Dental since I became owner of the practice in 2006. I vow to keep this in mind for both our patients and our fragile ecology.”
