Mind Your Mouth

Toothpaste packaging often promises to repair enamel, while social media insists it never comes back. In this episode of Mind Your Mouth, Dr Maria Florou, dentist and founder of Casuarina Dental, explains why both claims are partly right.Dr Florou outlines why tooth enamel, the hardest substance the body produces, has no living cells and therefore cannot regrow once it has been chipped, cracked or worn away. She then describes how the mouth is in a constant balance between demineralisation and remineralisation, and why softened enamel in the early stages can be rehardened, while a cavity cannot be repaired naturally.In this episode:- Why enamel cannot regrow, and what that means for your teeth- The chemistry behind "repairs enamel" claims- Decay as a daily tug of war between acid and minerals- What a white spot lesion is, and why timing matters- Four home strategies, in order of evidence: remineralising toothpaste, hydration and plaque control, quiet time between meals, and a healthy diet with adequate vitamin D- Remineralising creams based on CPP-ACP, and the caution for anyone who cannot have dairy- How to approach toothpaste claims that say "repairs enamel"Timestamps00:00 The toothpaste aisle vs social media debate01:11 Why enamel can't regrow02:03 The loophole in the chemistry02:47 Decay as a daily tug of war04:12 What is a white spot lesion?05:25 Why timing matters05:49 Four home strategies08:32 Remineralising creams and the dairy caution09:55 Final thoughts on "repairs enamel" claimsIf you found this episode useful, subscribe, leave a review and share it with someone who cares about their oral health.This episode is general education and isn't a substitute for personal dental advice.

Snoring sits on a spectrum, from simple snoring to obstructive sleep apnoea, where the airway closes repeatedly through the night. In this episode, Dr Maria Florou of Casuarina Dental explains the mechanics of snoring and the warning signs that warrant a conversation with your GP. She also covers three oral indicators dentists regularly observe: tongue scalloping, a crowded throat (Mallampati score) and teeth grinding.

She discusses research published in the New England Journal of Medicine linking disturbed night-time breathing with high blood pressure. She then outlines the diagnostic pathway through home sleep studies, and the treatment options recognised in joint guidelines from the American Academy of Sleep Medicine and the American Academy of Dental Sleep Medicine, including CPAP and custom oral appliances. All studies referenced are listed in the episode notes.

Apple cider vinegar shots and warm lemon water are wellness staples with genuine evidence behind some of their benefits — but very little of that conversation includes what they're doing to tooth enamel over time. In this episode, Dr Maria Florou walks through the chemistry of enamel erosion, reviews the clinical research on acidic drinks (including an eight-week trial on measurable tooth wear), and explains the difference between the "chemistry problem" of erosion and the more familiar "hygiene problem" of decay. The episode also covers three early clinical signs of erosion, the mechanics of saliva as a natural repair system, and practical, evidence-based adjustments — not restrictions — for anyone who isn't ready to give up their morning ritual.

In this episode, a dentist and gut health nutritionist explore the often-overlooked relationship between oral health and gut function. The conversation covers the physiological effects of the carnivore diet on gut microbiome diversity, the risks associated with antibacterial mouthwash use, and how nutritional deficiencies — particularly vitamin C — can present as visible signs in the mouth before appearing elsewhere in bloodwork. Listeners will also learn about natural antimicrobial alternatives to antibiotics for restoring gut balance, along with practical dietary guidance around fruit intake and fibre-rich whole foods. A useful listen for anyone interested in preventative health, integrative dentistry, or the emerging science connecting oral and gut microbiomes.

This episode explores the physiological relationship between oral health and gut health, examining how periodontal inflammation may influence systemic inflammatory markers and, in turn, gut and metabolic function. The conversation covers the role of prebiotic fibre in supporting a healthy gut microbiome, common missteps people make when introducing fermented foods and prebiotic-rich drinks such as kombucha, and evidence-informed approaches to restoring gut microbial balance following a course of antibiotics. Listeners interested in the intersection of oral health, digestive health, and holistic wellbeing will find practical, research-grounded guidance throughout.

The mouth is not an isolated part of the body. It contains a complex microbiome made up of bacteria, fungi, viruses and other microorganisms, and maintaining balance within this ecosystem is an important part of oral health.

In this episode, Dra. Maria Florou speaks with dietitian Carolina Rossi about the relationship between nutrition and the oral microbiome. They discuss how sugar frequency, acidic drinks, hydration, saliva, eating patterns and lifestyle factors can influence the oral environment.

The conversation explores why repeatedly consuming sugary foods and drinks can expose the mouth to acid, how saliva helps neutralise that acidity, and why continuously sipping drinks throughout the day may create additional challenges for dental health.

They also discuss nutrient-dense foods, plant foods, polyphenols, omega-3-rich foods and the relationship between the oral and gut microbiomes.

A valuable conversation for anyone interested in oral health, nutrition, microbiome science, cavities, gum disease and the connection between dental health and overall health.

Dental amalgam has been used for generations because it is durable, inexpensive and relatively forgiving during placement. But amalgam also contains approximately 50% elemental mercury by weight, raising important questions about mercury release, exposure and the long-term effects on both the tooth and the body.

In this episode, Dr Maria Florou examines the evidence surrounding dental amalgam from several perspectives. She explains how amalgam behaves mechanically inside a tooth, why it does not chemically bond to tooth structure, how mercury vapour can be released, and what studies have reported about mercury levels following amalgam exposure.

The discussion also addresses areas where the evidence is contested, including claims about mercury accumulation and long-term effects. Dr Florou emphasises the importance of understanding the quality and nature of individual studies rather than treating every claim as equally established.

The episode concludes with practical considerations around amalgam removal, including isolation, environmental controls and questions patients should ask their dentist before undergoing the procedure.

Inflammation is one of the most misunderstood concepts in health. While it's essential for healing and protecting the body, chronic low-grade inflammation has been associated with many of today's most common chronic diseases.

In this episode, Dr Maria Florou explains the science behind inflammation through the lens of oral health. You'll learn why the mouth is far more than a collection of teeth, how gum disease may influence the rest of the body, and what current evidence tells us about links between periodontal disease, cardiovascular health, diabetes, brain health and the oral microbiome.

Rather than relying on fear or sensational headlines, this episode breaks down complex science into practical, evidence-based explanations that help you better understand your own health.

Topics include:

• Acute vs chronic inflammation

• Systemic inflammation explained simply

• Oral microbiome and biofilm

• Gum disease and periodontal health

• Heart disease research

• Diabetes and blood sugar control

• Brain health and emerging evidence

• Why prevention starts with the mouth

Fluoride has been one of the most debated topics in modern dentistry, especially following recent policy changes in the United States.

In this episode, Dr. Maria Florou takes an evidence-based approach to one of oral health's most controversial subjects. Rather than relying on headlines or opinions, she examines the biological role of fluoride, the latest research on safety, the concerns surrounding systemic exposure, and practical recommendations for maintaining excellent dental health.

Whether you're a parent, health professional, or simply interested in science-backed information, this discussion provides the context needed to understand one of dentistry's biggest debates.
