Full radio interview — Dr. Yarden Goldstein with Zohar Tzemach-Wilson on biological dentistry, cavities, materials, and daily habits. (Listen via the image/audio on the original post.)
Dr. Yarden Goldstein: Nice to meet you.
Zohar: It sounds like architecture—level the mountain before building a house.
Dr. Yarden: That is where the problem starts. Most “holes” reflect a broader imbalance—diet, microbiome, and materials—not only a local drill-and-fill story.
Zohar: So there is logic to that. When you say sugars—do you mean croissants and breads too?
Dr. Yarden: Yes. Fermentable carbohydrates feed acid-producing bacteria. Frequency matters as much as amount. Refining the oral environment—reducing constant sugar exposure, supporting saliva, and choosing kinder materials—prevents the cycle of fillings that themselves need replacing.
Zohar: You said earlier the dentist must know the patient’s oral cavity—for example whether to fill a cavity or not?
Dr. Yarden: Exactly. Early demineralization can sometimes remineralize. Not every shadow needs a bur. We assess activity, hygiene, diet, and risk before intervening.
Zohar: It sounds like a face cream—but for teeth.
Dr. Yarden: Yes—remineralizing pastes and gels (for example CPP-ACP or related technologies) deliver calcium and phosphate to the surface. Abroad these are common; we use them when indicated alongside hygiene coaching.
Zohar: Are those pastes already available overseas?
Dr. Yarden: Yes, and some reach Israel through clinics or specialty channels. They are adjuncts, not magic—they work best with diet and plaque control.
Zohar: Chewing gums—are they widely used? Is xylitol one of those problematic sugar substitutes?
Dr. Yarden: Xylitol is different from many artificial sweeteners: oral bacteria cannot ferment it well, and it can reduce S. mutans counts with regular use. Look for high xylitol content; moderation matters for digestion. It is a tool, not a license for sugar grazing.
Zohar: So the only reason SLS is in toothpaste is foam?
Dr. Yarden: Largely yes—the foam feels “clean” but does not clean better. SLS can irritate mucosa and trigger aphthae in sensitive people. Foam is marketing psychology; detergent-free or low-SLS pastes are kinder for many mouths.
Zohar: Like breaking up a demonstration with a water hose…
Dr. Yarden: A vivid image—harsh chemistry that disperses everything instead of supporting a balanced microbiome.
Zohar: Many people brush in the morning. Health shops now sell fluoride-free pastes.
Dr. Yarden: Brushing timing and technique matter more than brand slogans. Fluoride has a long caries-prevention record; some patients prefer alternatives for personal or medical reasons. We discuss risk, diet, and remineralization options case by case rather than dogma.
Zohar: When you talk vitamins—diet or those tooth creams?
Dr. Yarden: Both layers. Fat-soluble vitamins (A, D, K2) and minerals support tooth and bone metabolism from inside; topical remineralizers work at the surface. Diet remains the foundation.
Zohar: Another problematic material—amalgam fillings. What are they?
Dr. Yarden: Amalgam is a mercury-containing alloy used for decades. It is durable and cheap, but mercury raises biological concerns—especially with vapor release during chewing, polishing, or removal. Biological dentistry prefers mercury-free materials and safe removal protocols when replacement is chosen.
Zohar: Over how many years is that mercury released?
Dr. Yarden: Release is ongoing at low levels and spikes with heat, abrasion, and bruxism. Individual burden varies with number of fillings, grinding, and detox capacity. We do not scare—we inform and plan carefully if removal is indicated.
Zohar: How many biological dentists are there in Israel today?
Dr. Yarden: Still a small community compared with conventional practice, but interest is growing—biocompatible materials, attention to the oral–systemic link, and patient-centered risk assessment.
Closing themes from the interview: prevent before you drill; respect the oral microbiome; question foaming detergents and unnecessary antibiotics; use xylitol and remineralization wisely; treat amalgam thoughtfully; and partner with a dentist who sees the mouth as part of whole-body health.
