A biological pediatric dentist in Kirkland takes every material and treatment decision through one filter: is this safe for a growing child’s body? At Evergreen Pediatric and Airway Dentistry, Dr. Susan Kim, a Columbia University-trained pediatric dentist and certified Vivos and HealthyStart provider recognized by Seattle Met as a Top Pediatric Dentist since 2012, helps families in Totem Lake, Kingsgate, and Moss Bay understand what biological dentistry means and whether it fits their child. The answer starts with knowing what sets this approach apart.
Most parents have never heard the term biological dentist until they start researching safer options. It is not a board specialty or a license category. It is a philosophy that drives material selection, treatment planning, and how a dentist views the relationship between oral health and the rest of the body. A child in Juanita or North Rose Hill who sees a biological pediatric dentist gets an experience built around what supports whole-body development rather than what is simply standard practice.
What Makes a Dentist Biological
A biological pediatric dentist prioritizes materials that work with a child’s developing body rather than ones that simply work on teeth. That means BPA-free composites instead of materials that release bisphenol A derivatives, fluoride alternatives like hydroxyapatite varnish for families who prefer them, and treatment approaches that avoid unnecessary chemical exposure. The word biological reflects the belief that the mouth is connected to the whole body and that dental care decisions should honor that connection.
At Evergreen Pediatric and Airway Dentistry, Dr. Susan Kim applies this thinking to every appointment. She evaluates airway health alongside cavities, considers jaw development when planning treatment, and explains the reasoning behind every material before she picks up a single instrument. Families in South Rose Hill and Houghton who have switched from conventional practices say the biggest change is how much more they understand about what is happening in their child’s mouth.
How This Differs from Conventional Pediatric Dentistry
Conventional pediatric dentistry is built around proven clinical outcomes and widely accepted materials. It works well for the vast majority of children and delivers excellent results every day. The difference with a biological approach is not that conventional care is wrong. It is that biological dentistry asks additional questions before reaching for a material or recommending a treatment.
A conventional practice may use BPA-derivative composites because they are durable and widely approved. A biological practice reaches for BPA-free alternatives first. A 2020 systematic review published in Environmental Health Perspectives found that urinary BPA concentrations increase measurably within 24 hours of dental treatment with resin-based materials in children. That finding drives the material choices Dr. Susan makes every day for young patients in Kirkland.
BPA-Free Materials, Fluoride Alternatives, and Metal-Free Crowns
At Evergreen Pediatric and Airway Dentistry, biocompatible material selection shows up at every step of care. BPA-free composite resin is used for fillings, metal-free zirconia crowns replace stainless steel when a crown is necessary, hydroxyapatite varnish is available as a fluoride alternative, and low-radiation digital X-rays reduce exposure at every appointment. Each choice is intentional and explained clearly before any treatment begins.
| Procedure | Conventional Approach | Biological Approach at Evergreen Pediatric |
| Cavity filling | BPA-derivative composite | BPA-free composite resin |
| Prevention varnish | Sodium fluoride varnish | Hydroxyapatite varnish available |
| Pediatric crown | Stainless steel crown | Metal-free zirconia crown |
| X-ray exposure | Standard digital X-ray | Low-radiation digital X-ray |
| Early decay | Drilling and filling | Ozone therapy for eligible lesions |
The goal is never to make parents feel that conventional dentistry has harmed their child. The goal is to give families in Finn Hill, Forbes Creek, and Everest the most biocompatible option at each step so decisions match their values and their child’s health needs.
Why Airway Health Is Central to Biological Dentistry
Biological dentistry does not stop at material selection. It extends to how a dentist views the mouth’s role in a child’s overall development, and airway health sits at the center of that view. A child who breathes through the mouth instead of the nose is at risk for altered jaw development, crowded teeth, and disrupted sleep, and a 2022 review in Frontiers in Public Health confirmed that uncorrected mouth breathing can result in narrowed palates and increased malocclusion risk in children.
- Airway screening at every preventive visit to catch developing concerns early
- Evaluation of jaw width, palate shape, and tongue posture alongside teeth and gums
- Identification of tongue tie and lip tie that may restrict jaw development
- Vivos and HealthyStart certified treatment coordination when appropriate
- Clear explanation to parents of what airway findings mean and what options exist
Biological dentistry treats the child in the chair, not just the teeth in that child’s mouth. When airway and material choices align with whole-body health, children in Norkirk, Lakeview, and Central Houghton leave each visit in better shape than when they arrived.
Is a Biological Pediatric Dentist Right for Your Child?
Whether a biological approach fits your child depends on your family’s priorities and clinical needs. Some children have straightforward needs that any well-trained pediatric dentist can address. Other families want every material and treatment filtered through a whole-body, biocompatible lens, and both are valid decisions that belong to the parent.
The best way to know is to come in and ask the questions that matter to you. Dr. Susan makes time at every appointment to walk parents through material choices, airway findings, and treatment options without rushing the conversation. Families in Highlands, Bridle Trails, and Lake Washington Ridge consistently say that first visit gave them more useful information than years of conventional checkups.
Your Child’s Health Starts With the Right Dental Partner
Dr. Susan Kim built Evergreen Pediatric and Airway Dentistry on the belief that every child deserves a dentist who looks at the whole picture.

Frequently Asked Questions
What is the difference between a biological dentist and a holistic dentist?
The terms are closely related and often used interchangeably, but biological dentistry places stronger emphasis on the scientific research behind material safety and the measurable connection between oral health and systemic disease. Holistic dentistry shares the same values around biocompatible materials but sometimes extends further into wellness practices like nutrition and detoxification. At Evergreen Pediatric, Dr. Susan Kim applies biological principles through BPA-free materials, fluoride alternatives, and airway screening at every visit.
Does biological dentistry mean my child cannot get standard dental treatments?
A biological approach changes which materials are used and how decisions are made, not whether your child can receive the care they need. Dr. Susan performs fillings, crowns, cleanings, X-rays, frenectomies, and airway evaluations at Evergreen Pediatric, all selected and performed with a biocompatible, minimally invasive lens. A child who needs a crown gets zirconia instead of stainless steel, and a child with early decay may be treated with ozone instead of a drill.
Are BPA-containing dental materials actually harmful to children?
Research shows BPA-derivative dental materials release measurable BPA, and a 2020 systematic review in Environmental Health Perspectives found that urinary BPA concentrations increase significantly in children within 24 hours of dental treatment with resin-based composites. The long-term clinical significance of that exposure is still being studied, and most conventional materials are considered safe by regulatory standards. Dr. Susan takes a precautionary approach by selecting BPA-free alternatives wherever clinically appropriate for families in Kirkland.
How does airway screening fit into biological pediatric dental care?
Airway screening connects to biological dentistry’s core belief that the mouth affects the whole body. A child who chronically mouth-breathes is at risk for narrowed jaw development, crowded teeth, disrupted sleep, and behavioral changes tied to how the airway is functioning. Dr. Susan evaluates airway health, jaw width, tongue posture, and breathing patterns at every Evergreen Pediatric visit, catching problems while treatment options are still straightforward.
