Providing transformative care to health-conscious families & individuals through high-tech holistic dentistry. We're so glad you're here - come on in!

Life-Changing Biological Dentistry Based in Woodinville, Serving Families Near & Far.

At Sustineri Dental, we offer more than a pretty smile. We partner with you & your family to prevent disease & create sustainable health using functional medicine & high-tech holistic dentistry.

What we do:

We are a mercury-safe & fluoride-free dental office offering safe removal of amalgam (silver) fillings & mercury detox support. We use only low-radiation imaging, ozonated water & laser dentistry to provide the least-invasive care possible. 

Non-Toxic & Safe

Personalized Care

We don't believe in "one-size-fits-all" care. Every individual is unique, and we shape our treatment plans accordingly! This involves diagnostic testing, custom diet & lifestyle protocols & practices such as “biocompatibility testing”, which help us select the most suitable dental materials for your mouth. 

What you can count on:

Root-Cause Approach

We are committed to helping you identify the root-cause behind your symptoms. Even when symptoms don't appear to be related your mouth, there's a good chance they are! Your mouth is connected to all of the organs & systems throughout your body, and our job as biological dentists is to help you make connections that may otherwise go undetected.

Some call it biological dentistry, others call it biomimetic dentistry, bio-functional dentistry, holistic dentistry, or natural dentistry.

But, what it comes down to for us is considering your entire state of well-being: physical, mental, & spiritual. 

It’s about helping you achieve optimal & sustainable wellness using a combination of cutting-edge dental technology & functional medicine principles.

Believe it or not, when we look inside your mouth, we see a lot more than just teeth! In fact, your mouth gives us important clues about what’s going on in the rest of your body (e.g. with your organs & within your gut).

And from there, we’re able to recommend diet & lifestyle solutions to help restore balance & vitality. 

At its core, biological dentistry is about addressing the root cause of disharmony within the mouth, rather than just treating the symptoms.

Much like functional & naturopathic medicine, we aim to cause no harm, which also means safe & non-toxic products.

Holistic dentists tend to be primarily focused on avoiding toxins, whereas biological dentists focus on restoring function throughout the body from an oral health perspective. Using functional diagnostic testing & personalized diet & lifestyle protocols, we assist the body in its own innate healing abilities.

Biological Dentistry FAQ

It’s natural to have lots of questions, especially if biological dentistry & functional medicine are new to you! But the good news is that we meet you exactly where you are, providing you everything you need to make an informed decision for you & your family.

Yes! Existing amalgam (silver) fillings are removed according to the International Academy of Oral Medicine & Toxicology guidelines. This significantly reduces your exposure to toxic mercury during the removal process. We also offer heavy metal blood testing & mercury detox support.  

Do you remove mercury fillings as a biological dentist? 

Absolutely. We are happy to speak with your Naturopathic Physician or Functional Medicine Doctor, and we really enjoy doing so! This type of collaboration leads to better, faster results for you. 

Are you available to consult on medical issues with my doctor? 

Absolutely! We offer preventative & speciality services for the whole family. We love the opportunity to see kids because we’re able to catch things early, providing a lifetime of benefit. 

I’m looking for a biological dentist for my child - do you see kids? 

Your first visit will include lots of questions about your medical history, so we can get to know you! Then we’ll perform a comprehensive oral exam. We always explain what we’re doing, with the goal of empowering you along the way. After that, we’ll chat about our findings & put a plan into place to help you achieve your health goals. 

I’ve never seen a biological dentist before - what should I expect?

Yes, we do! We realize that coming to the dentist can create anxiety for some people. Our IV sedation ensures that you feel safe and comfortable during all procedures. We have three levels of sedation depending on your anxiety level & the type of procedure you're undergoing..

I’m looking for a biological dentist that offers IV sedation - do you do this?
