Episode Details

Holistic, biological, functional — is there actually a difference, or is it all just marketing?
Are root canals really dangerous — or is that just what the algorithm keeps showing your patients?
When a patient wants their sound fillings out, do you test, reassure, or drill?
And how do you bring sleep, diet and blood tests into a dental appointment without it stopping being dentistry?
This episode sits down with Dr James Goolnik (https://uk.linkedin.com/in/james-goolnik)— clinical dentist, founder of the London holistic practice Optimal Dental Health, past President of the British Academy of Cosmetic Dentistry, and one of Jaz’s earliest mentors. James openly calls himself a holistic and biological dentist, which makes him the ideal person to separate the thoughtful, evidence-aware end of this world from the online extremism that gives it a bad name. Expect a balanced, honest conversation: some of it you’ll adopt tomorrow, some of it you’ll want to pressure-test — which is exactly the point.

Protrusive Dental Pearl: Dentistry Isn’t Just About Fixing Teeth

This one isn’t a clinical tip — it’s a sentiment that frames the whole episode. Dentistry isn’t just about fixing teeth; it’s about improving health. You don’t have to agree with every claim made in biological dentistry — but you will struggle to disagree that a patient’s diet, sleep, breathing, stress and inflammation all influence oral health.

So the pearl is simple: stay curious, stay open-minded — but stay critical, and never stop asking better questions.

What You’ll Take From This Episode

• The holistic–biological spectrum — what each word actually means, and where thoughtful practice tips into online extremism.

• Test or reassure? — the three-question filter for deciding whether any test earns its place before you order it.

• Safe amalgam removal — the SMART protocol, and when a worried patient’s sound filling should be left well alone.

• The mouth-body connection — how sleep, glucose control and systemic inflammation affect the mouth, and where to refer.

• The balanced take on root canals and implants — whether root canals are dangerous, and titanium versus ceramic with metal-allergy testing.
