About PJN Dental
PJN Dental is a holistic and biological dental clinic at 17535 SW Tualatin Valley Hwy in Beaverton, Oregon, serving the Portland area. The clinic treats oral health as inseparable from whole-body health, looking beyond individual teeth to the airway, the jaw, dental materials and each patient's health history. Its stated approach is to evaluate multiple treatment paths, select the safest materials available, and look for the root of a problem rather than its surface symptoms.
The work recorded here includes mercury amalgam removal under the SMART protocol, evaluation and treatment of cavitations, zirconia and other ceramic implant placement, biocompatible restorations, biocompatibility testing, oxygen ozone therapy, Fotona laser dentistry, safe extraction and removal of root canal-treated teeth, airway-focused orthodontics, and TMJ and functional bite optimization. Clinicians at this clinic are recorded with the Holistic Dental Association, the International Academy of Biological Dentistry and Medicine, and the International Academy of Oral Medicine and Toxicology.

Common Questions
How does PJN Dental approach mercury amalgam removal?
The clinic follows the internationally recognized SMART protocol rather than simply drilling an amalgam filling out. It states that improper removal can increase exposure to mercury vapor and particulate matter for both patients and dental staff, so the protocol's precautions are applied throughout the removal to limit that exposure.
What metal-free option is offered for replacing a missing tooth?
Ceramic, or zirconia, dental implants are offered as a biocompatible, metal-free alternative for patients who want a holistic approach to tooth replacement. The stated goal is restoring function while supporting the body's own biology, and each patient is evaluated to determine whether ceramic implants are an appropriate choice for their long-term health.
How does the clinic decide which dental materials suit a particular patient?
Material selection can be informed by biocompatibility testing, which analyzes an individual's sensitivities to dental materials and returns a comprehensive report from BioComp Labs. The clinic uses that analysis to select compatible materials, orders materials custom when necessary, and tracks newly available biocompatible options. Whether testing is appropriate is determined at consultation.
What is cavitation treatment, and when would it be considered?
After a tooth extraction the jawbone should heal completely. When healing is incomplete, areas of chronically inflamed or unhealthy bone known as cavitations can remain. The clinic treats evaluation of these sites as important when a patient has persistent oral concerns or when imaging suggests that healing did not finish.
How is oxygen ozone therapy used here?
The clinic describes ozone as one of the most valuable tools in biological dentistry because it supports the body's natural healing processes rather than masking symptoms, and notes it has been used in medicine and dentistry for decades to reduce microbial burden while encouraging healthy tissue regeneration. Ozone is incorporated where it can enhance healing.
What does the clinic look at for jaw pain or a problem bite?
The clinic treats the bite as influencing more than the teeth: jaw joints, muscles, airway, posture and facial function work together, and imbalance can produce jaw pain, headaches, tooth wear and muscle tension. Its TMJ and functional bite work aims to identify the underlying causes rather than addressing those symptoms alone.
