Welcome to Denver Dentistry
A comfortable environment for comprehensive holistic dental care


About Us

Our highly trained team practices functional dentistry from a holistic standpoint, carefully analyzing your system as a whole instead of a collection of different body parts. At your appointment(s) we will evaluate how your systemic health affects your oral health. Then, we integrate both traditional and alternative dental treatments to improve your well-being both systemically and orally. If dental or gingival therapies are needed, we only use the most biocompatible materials available to minimize your exposure to any toxins that have the potential to cause systemic complications.

Our Patients Are Saying

Meet the Providers

Dr. Guy Grabiak

Dr. Guy Grabiak DMD, FAGD

Throughout my career, I have been blessed to study with some of the leaders and greatest minds in organized dentistry, but I intuitively realized there was a better way to achieve optimal health. The last mercury amalgam filling I placed was while still in the United States Air Force over 20 years ago.

Gradually, I noticed that our population’s decline in health, despite advances in medicine, was due in part to western medicines’ lack of understanding of the complexities of how the mind, body, and spirit integrate. We were too quick to prescribe antibiotics and narcotic pain medications rather than treat the cause of the disease.

Angelina Geon, RDH, BSDH, HIAOMT

I am a native of Colorado and have over 20 years of experience in the dental field.

I attended the University of Bridgeport, Fones School of Dental Hygiene graduating Magna Cum Laude with a Bachelor of Science in Dental Hygiene. Then continued on to earn accreditation in Biological Dental Hygiene through the International Academy of Oral Medicine and Toxicology.

Like most who seek alternative therapies, I pursued biological dental hygiene to be more congruent with my values, beliefs, and philosophical orientations toward health and life. I was dissatisfied with helping my patients only manage their gum disease, in the traditional dental setting. I wanted to address the root cause, and actually support my patients’ quest to improve their oral and systemic health. Biological dental hygiene helped me to do just that!

I take pride in educating practice clientele while respecting each individual’s goals, values, and preferences. The drive to create and maintain beautiful, healthy smiles leads me to review new scientific research, explore the latest clinical techniques, and analyze oral health care products. Armed with this knowledge, I empower my patients to make the right choice for their oral health in consideration of their systemic health.

When not on the job, you can find me biking or hiking the Rocky Mountains with my family, satisfying my sweet tooth by experimenting with new recipes, or on the baseball field watching my son hit, run, and score. My goals for the future are to maintain a good work life balance, while capturing all that a career in biological dental hygiene has to offer.

Biocompatibility Dentistry

Biocompatibility Dentistry

Dental/oral conditions have a big impact on your overall health and well-being. With every procedure, we consider its potential effect on the rest of your body. It’s why we encourage biocompatibility testing of dental materials and will not use known neurotoxins such as mercury amalgam to repair decayed or damaged teeth. It’s why we use tools such as pathogen testing, to provide more specific, targeted treatment of gum disease – a condition linked to heart disease, stroke, diabetes, rheumatoid arthritis and other inflammatory conditions. We don’t just look at teeth. We look at the big picture.

We offer a variety of non-invasive alternative periodontal therapies that can be tailored to your specific needs.

Noelle's dedication to dental excellence and her commitment to a holistic approach in her field make her a pivotal member of the Denver Dentistry team.

The foundation of providing safe and personalized holistic care begins by getting to know you and your goals for your oral health and overall health, both short term and long term. Dr. Grabiak will then learn about your family’s dental and medical history, along with your dental and medical history. Afterwards, we begin your exam by taking a sample of your saliva (Sillha), checking for seven different biomarkers. That same day, we will send you home with a report showing how you scored in those different biomarker categories.

The head and neck examination is often overlooked by busy clinicians but it is as crucial as an element of the oral cancer examination. Dr. Grabiak begins his exam outside of the mouth by starting with a soft tissue check of the neck and the jaw. A thorough head and neck examination is essential for detecting early skin cancers, any overdeveloped jaw muscles that may be contributing towards bruxism, and enlarged lymph nodes that may indicate an active virus or infection.

After the extraoral exam, Dr. Grabiak begins his extensive intraoral exam. During Dr. Grabiak’s exam he is evaluating the teeth, uvula, mucosal tissues, tongue, floor of the mouth, hard and soft palate, and the oropharynx. Part of this exam includes taking high-definition photos of the mouth, all at different angles so you can see exactly what he is seeing. Our hygienist will then come in and complete a comprehensive periodontal assessment. In some cases, Dr. Grabiak and your hygienist may recommend additional testing to get to the root cause of the evidence of symptoms they are seeing in your mouth. This entire process takes roughly an hour. In some cases, depending on what Dr. Grabiak and your hygienist had found during their exam we will invite you back for a follow-up appointment called review of findings.

In preparation for the review of findings, Dr. Grabiak and your hygienist will take the time to evaluate all of the data that was collected from your examination and testing to determine your specific needs. At your review of findings appointment Dr. Grabiak will sit down with you one on one to review the data that was collected from your appointment, along with any recommendations. This allows you the time to ask Dr. Grabiak any questions that you may have about your treatment recommendations and expectations from treatment.
