We’re taught to think about what we eat, how we move, and how we care for our gut. But rarely are we asked to think about our mouth in the same way.

The oral microbiome is a complex, living ecosystem, and its influence extends well beyond teeth and gums.

At Gutology, we believe understanding this often-ignored space is key to understanding the body as a whole.

In this episode of The Gutology Podcast, we speak with Dr James Goolnik to explore how daily routines, toothpaste ingredients, and even the way we sleep can shape oral and systemic health.

Who is James Goolnik? 

James Goolnik is not your typical dentist. With years of clinical experience and a reputation for innovative thinking, James combines traditional dentistry with cutting-edge insights into oral microbiology and systemic health. His clinic, Optimal Dental Health, focuses on preventive care, patient education, and understanding the root causes of oral issues rather than just treating symptoms. His work aligns closely with Gutology’s mission: supporting the microbiome and holistic wellness from the inside out. 

Oral health, microbiomes, and everyday habits

In the podcast, James challenges some common practices that most of us take for granted:

• The first thing you put in your mouth is… SWEET? Many toothpastes contain artificial sweeteners, which can inadvertently increase sugar cravings. James explains how our morning toothpaste could be influencing tastebuds and creating patterns of sugar dependency.  (03:41)
• Stop using mouthwash - Here’s why. Daily alcohol-based mouthwash may disrupt the delicate oral microbiome, contributing to bad breath, oral thrush, and even tooth decay. James highlights how preserving beneficial bacteria in our mouths is essential for overall health. (06:07)
• Snoring isn’t normal - it’s a warning sign. Snoring isn’t just a nuisance; it can indicate airway obstruction and poor oxygenation during sleep, impacting energy, cognition, and cardiovascular health. (12:31)
• Why your child might NOT need braces. Contrary to popular belief, proper tongue posture and chewing can naturally guide jaw development. Many children are given braces unnecessarily, and James explores how natural oral development can prevent future dental issues. (7:03)
• Bleeding gums = leaky gut? Oral inflammation can allow bacteria to enter the bloodstream, affecting systemic health. James draws fascinating connections between gum health and gut integrity, reinforcing the importance of a microbiome-focused approach. (25:15)
• The cheapest health hack? A Spoon. Using a spoon as a tongue scraper is a simple, 10-second daily habit that can boost oral nitric oxide, freshen breath, and support overall oral wellness. (57:50)
• The glucose spike you didn’t eat. Stress can spike blood glucose more than food. James discusses how oral health and systemic health are interconnected, highlighting the importance of lifestyle factors. (46:40)
• Your dentist can predict major health issues. Your dentist can spot early signs of pregnancy, diabetes, and even cognitive decline. James emphasises how oral examinations are a window into systemic health. (29:17)
• 10-day tastebud reset for sugar cravings. Tastebuds regenerate approximately every 10 days. James shares practical strategies to “reset” taste preferences and reduce sugar dependency. (3:03)
• “One thing I wish everyone knew about their teeth…” Bleeding gums are never normal, much like washing your hands shouldn’t make them bleed. James’s analogies bring attention to the overlooked warning signs in oral health. (24:32)
• “Our mouth taping transformation story.” A personal story from James’s family illustrates how simple interventions, like mouth taping during sleep, can improve sleep quality and morning mood, reinforcing the link between oral habits and overall wellbeing. (14:12)

Gutology’s Approach: Supporting Your Oral and Gut Microbiome

At Gutology, we are committed to creating products and practices that support the microbiome, both oral and gut. Our microbiome-focused toothpaste and oral products align with James’s insights: avoiding harsh chemicals, supporting beneficial bacteria, and promoting long-term health rather than quick fixes. This podcast is more than dental advice, it’s a conversation about how everyday choices ripple through our health, from oral hygiene to systemic wellbeing.
