4 Key Concepts
Oral Microbiome
The second largest and most diverse microbiome after the gut, containing over 700 different species of bacteria (totaling 2 billion) within various mini-environments in the mouth. It influences systemic health as bacteria can be swallowed, travel through blood via gums, or be inhaled.
Periodontal Disease (Gum Disease)
A spectrum of inflammatory conditions affecting the gums, starting with inflamed, bleeding gums (gingivitis) and progressing to bone loss around the teeth, eventually leading to tooth loss. It is the sixth most prevalent inflammatory condition globally and is largely preventable.
Host Immune Response (in oral health)
The individual's genetic predisposition and how their body reacts to oral bacteria, which can determine susceptibility to gum disease and decay even with similar oral microbiomes or good hygiene practices. This explains why some people with minimal bad bacteria still develop severe issues.
Collagen Breakdown (in saliva)
A biomolecular indicator of gum disease, detectable in saliva up to a year before visible symptoms appear in the mouth. It also serves as a marker for physical or emotional stress, as high levels can be found in individuals experiencing significant stress, even with otherwise healthy gums.
10 Questions Answered
Oral health is strongly linked to conditions like diabetes, cardiovascular disease, chronic kidney disease, infertility, Alzheimer's, arthritis, and certain cancers (e.g., colorectal cancer).
Gum disease (periodontal disease) is the sixth most prevalent inflammatory condition worldwide, affecting over 3.5 billion people, with over 10% of the global population having periodontal disease.
Yes, treating periodontal disease in patients with type 2 diabetes has been shown to reduce their HbA1c (average blood sugar marker) by 0.4%, which is comparable to adding a second medication.
Research has found a specific oral bacteria, Porphyromonas gingivalis, and its virulence factors (gingipanes) in the cerebral spinal fluid of Alzheimer's patients, and treating gum disease in these patients can slow cognitive decline.
Not necessarily; current research suggests that it's not just the diversity or balance of bacteria, but also specific strains and the individual's host immune response that determine oral health outcomes.
The only real early warning sign of gum disease is bleeding gums, which is very common but often mistakenly considered normal by many people.
Every time you snack, the acidity of your saliva increases, which can demineralize teeth and lead to decay. Constant snacking doesn't allow saliva enough time to neutralize and rebalance.
Nasal breathing prevents the mouth from drying out, which is crucial because saliva is vital for oral health. Mouth breathing introduces more bacteria and reduces saliva production, impacting the oral microbiome.
Mouthwash should generally be prescribed by a dentist for specific problems, as daily use, especially with alcohol-containing versions, can disrupt the oral microbiome balance. It's best used sparingly, like a perfume, for temporary breath freshening.
For women, uncontrolled gum disease during pregnancy increases the risk of preterm birth and low birth weight. For men, gum disease makes them 2.85 times more likely to experience erectile dysfunction and can negatively impact sperm quality and motility, affecting conception rates.
14 Actionable Insights
1. Prioritize Regular Dental Hygiene
Schedule a professional hygiene appointment at least every six months, as this practice can significantly reduce inflammatory markers and improve blood glucose levels, potentially lowering HbA1c by 0.4% in diabetic patients.
2. Spit, Don’t Rinse After Brushing
After brushing your teeth for two minutes, spit out the toothpaste but avoid rinsing your mouth with water, as rinsing washes away the beneficial ingredients from the toothpaste that protect your teeth.
3. Encourage Nasal Breathing at Night
Practice nasal breathing during sleep, potentially using mouth tape, to prevent your mouth from drying out and to avoid introducing unwanted bacteria, as saliva is critically important for maintaining oral health.
4. Strategic Snacking for Oral Health
Avoid frequent snacking, especially on sugary items, throughout the day; instead, consume all treats at once, followed by water, because each snack increases saliva acidity, leading to demineralization and decay.
5. Rinse Mouth After Meals/Treats
After consuming anything sugary or acidic, or after any meal, rinse your mouth with water to remove food remnants and help neutralize saliva acidity, but do not brush immediately after acidic intake.
6. Floss Before Brushing
Floss your teeth before brushing, as over 30% of bacteria reside between your teeth, and flossing first effectively removes these before brushing cleans the rest of your mouth.
7. Address Bleeding Gums Promptly
Recognize bleeding gums as an early warning sign of potential gum inflammation or disease, and seek professional dental advice if you experience them, as they are not normal.
8. Avoid SLS in Toothpaste
Choose toothpastes that do not contain sodium lauryl sulfate (SLS), a foaming agent that can irritate soft tissues in the mouth, cause ulcers, and negatively impact the oral microbiome.
9. Judicious Mouthwash Use
Use mouthwash sparingly and only when prescribed by a dentist for a specific problem, opting for alcohol-free options and using it at a separate time from brushing to avoid disrupting the oral microbiome or canceling out toothpaste effects.
10. Prioritize Oral Health During Pregnancy
Pregnant individuals should have a professional hygiene appointment every three months, as untreated gum disease during pregnancy significantly increases the risk of preterm birth and low birth weight.
11. Promote Jaw Development in Children
Encourage children to eat harder, crunchy foods like carrots to provide mechanical stimulus for proper jaw development, rather than relying solely on soft, ultra-processed foods.
12. Consider Oral Microbiome Testing
Explore oral microbiome testing (e.g., Oralis1) to gain a deeper understanding of your oral health and potential risks, which can empower you to seek appropriate dental care and lifestyle changes.
13. Wait to Brush After Eating
Wait a minimum of 30 minutes after eating, especially after consuming acidic or sugary foods, before brushing your teeth to allow your saliva to naturally neutralize acids and prevent grinding acid into your tooth enamel.
14. Moderate Tongue Scraping
Incorporate tongue scraping into your routine a couple of times a week using an ayurvedic metal tongue scraper, being careful not to scrape too aggressively to avoid damaging tongue buds.

The mouth is the gateway to the rest of the body.

If your eye was bleeding, you'd probably be a little bit worried, right? You'd probably go and see your doctor... But when it comes to the mouth, we often don't know... And bleeding gums, people think, is just entirely normal.
Dr. Victoria Sampson
You can't have a balanced gut microbiome if your oral microbiome is imbalanced. And you can't have a balanced vaginal microbiome if your gut microbiome, you know, it all has to be balanced for it to work properly.

Every part of your body, you know, if you have a problem or you have some sort of trauma, you can hide it. But in your mouth, your mouth shows so much.
Dr. Victoria Sampson (quoting a patient)
If you have a bag of Skittles, I'd rather you ate the whole bag of Skittles in one go, then you ate a Skittle every, you know, five minutes or so.
Dr. Victoria Sampson
No mouthwash that we recommend should have alcohol. I mean, at this point in day, like, we shouldn't be having alcohol in any of our mouthwashes.
