Oral health is a crucial part of overall wellness, yet it is often overlooked when discussing nutrition. The mouth is the gateway to the body, and the health of the oral cavity influences many systemic conditions, from cardiovascular health to gut function. A real food approach to nutrition can profoundly impact oral health, not only by reducing cavities but also by supporting the oral microbiome, maintaining strong teeth, and preventing gum disease.
Read on here to learn about a real food approach.
The Oral Microbiome: A Key Player in Oral Health
The oral microbiome is a complex ecosystem of bacteria, viruses, fungi, and other microorganisms that live in the mouth. Like the gut microbiome, the oral microbiome plays an essential role in maintaining health. A balanced oral microbiome helps protect against harmful pathogens, regulates the pH of the mouth, and supports tissue health.
However, poor dietary choices—especially those high in refined sugars and processed foods—can disrupt this balance, leading to oral dysbiosis. This can result in issues such as cavities, gum disease (periodontitis), bad breath (halitosis), and even systemic inflammation.
Key Factors that Affect the Oral Microbiome
- pH Levels: The pH of the mouth is critical for maintaining the balance of beneficial bacteria. A more acidic environment (pH below 5.5) can demineralize tooth enamel, promoting the growth of harmful bacteria.
- Diversity of Microbiota: A diverse and well-balanced microbiome protects against harmful microbes that cause tooth decay and gum disease.
- Saliva Production: Saliva acts as a natural cleanser, washing away food particles, neutralizing acids, and providing antimicrobial proteins. Proper hydration and nutrient intake are vital for maintaining healthy saliva flow.
Nutrients Essential for Oral Health
Calcium
Calcium is the primary mineral found in teeth and is essential for keeping enamel strong. It also supports jawbone density, which is crucial for healthy teeth alignment.
Top Food Sources: Bone-in fish, grass-fed dairy products (if tolerated), leafy greens (kale, spinach), bone broth, almonds, and sesame seeds. Read more on real food sources of calcium here
Vitamin D
Vitamin D helps the body absorb calcium and phosphorus, promoting strong teeth and bones. Deficiency in vitamin D has been linked to an increased risk of cavities and gum disease.
Top Food Sources: Fatty fish (salmon, mackerel), egg yolks, cod liver oil, and mushrooms. Regular sun exposure also helps increase vitamin D levels. Learn more about Vitamin D in this post
Phosphorus
Phosphorus works synergistically with calcium to build strong teeth and bones. It also helps repair damaged enamel.
Top Food Sources: Grass-fed meats, poultry, eggs, wild-caught fish, and nuts.
Vitamin K2
Vitamin K2 is essential for guiding calcium to the right places, such as the teeth and bones, and away from areas where it could cause harm, like soft tissues. It activates osteocalcin, a protein that binds calcium to teeth.
Top Food Sources: Grass-fed dairy, fermented foods (sauerkraut, natto), organ meats (liver), and egg yolks. Incorporate more organ meats into your diet using these tips
Collagen
Collagen is a structural protein that supports gum tissue, tooth dentin, and jawbone integrity. It’s essential for healing and maintaining the soft tissues in the mouth.
Top Food Sources: Bone broth, gelatin, collagen supplements, and animal skin. Get the best bone broth delivered right to you – order here
Magnesium
Magnesium is critical for tooth remineralization and helps the body efficiently use calcium. Deficiency can lead to tooth decay and weak enamel.
Top Food Sources: Dark leafy greens, nuts, seeds, avocados, and dark chocolate.
Vitamin C
Vitamin C is essential for healthy gum tissue and helps prevent gingivitis and periodontitis. It also promotes collagen production, crucial for gum health.
Top Food Sources: Citrus fruits, bell peppers, strawberries, kiwi, and leafy greens.
Zinc
Zinc helps with wound healing and has anti-inflammatory properties, which are beneficial for gum health. It also plays a role in maintaining a healthy oral microbiome by inhibiting harmful bacteria.
Top Food Sources: Red meat, shellfish and seeds.
Foods to Prioritize for Optimal Oral Health
Whole, Unprocessed Foods
Whole foods rich in essential nutrients, like calcium, vitamin D, and vitamin K2, provide the building blocks for strong teeth and gums. Minimally processed animal proteins, seasonal vegetables, and naturally occurring fats are the foundation of a diet that supports oral health.
Fibrous Vegetables
Crunchy, fibrous vegetables (like celery, carrots, and apples) help mechanically clean teeth by stimulating saliva production and acting like natural toothbrushes. Additionally, these vegetables are rich in vitamins and minerals essential for gum health.
Healthy Fats
Healthy fats, especially those rich in fat-soluble vitamins like A, D, E, and K, promote the absorption of key minerals like calcium and magnesium. Fats from sources such as pasture raised animals, wild-caught fish, grass-fed butter, and avocados help keep inflammation in check and support gum health. Download our real food Fat Guide here
Fermented Foods
Fermented foods, such as sauerkraut, kimchi, kefir, and kombucha, support a healthy oral microbiome by populating the mouth with beneficial bacteria. These probiotics help balance the microbial environment and reduce the risk of oral infections and gum disease.
Raw Dairy (If Tolerated)
Raw dairy products are rich in calcium, phosphorus, and probiotics, all of which support tooth remineralization and a healthy oral microbiome. However, individuals with dairy intolerance should opt for other calcium-rich alternatives like leafy greens and bone broth. Read on here for more on the dairy debate.

Foods to Avoid for Optimal Oral Health
Refined Sugars and Carbohydrates
Sugar feeds harmful bacteria in the mouth, leading to plaque buildup, cavities, and gum disease. The bacteria that thrive on sugar produce acids that erode tooth enamel, creating a more acidic environment conducive to decay.
Processed Foods
Processed foods often contain additives, preservatives, and sugars that disrupt the oral microbiome and lead to inflammation. They are also stripped of the nutrients necessary for maintaining healthy teeth and gums.
Acidic Foods and Drinks
Foods and drinks high in acid, like soda, citrus juices, and vinegar, can erode tooth enamel. While some acidic foods (like lemon and apple cider vinegar) have health benefits, it’s important to consume them in moderation and rinse the mouth with water afterward.
Grains and Phytic Acid
Grains, especially those not properly prepared, contain phytic acid, which can bind to calcium and other minerals, preventing their absorption. This can lead to deficiencies that impact dental health. Opting for sprouted or fermented grains can reduce phytic acid levels. Learn more about ancient and gluten-free grains in this post
Hydration and Oral Health
Proper hydration is essential for producing saliva, which plays a vital role in maintaining oral health. Saliva helps neutralize acids, re-mineralize teeth, and wash away food particles. Drinking enough water throughout the day, particularly fluoride-free water, is key to supporting the oral microbiome and maintaining a healthy pH balance in the mouth.
Practical Tips for Implementing A Real Food Oral Health Diet
Focus on Nutrient Density: Make each meal rich in the nutrients that support oral health—prioritize calcium, fat-soluble vitamins (D, A, K2), and protein from quality sources like grass-fed meat, pastured eggs, and wild-caught fish.
Incorporate Bone Broth: Bone broth is rich in collagen, calcium, and magnesium, all of which support gum health and strong teeth. Aim to include it in your diet regularly. No need to spend hours making bone broth – get it delivered! Order here
Choose Whole Fruits Over Juices: Whole fruits contain fiber that helps clean teeth and maintain balanced blood sugar levels. Fruit juices, even if fresh, are highly concentrated in sugars and acids that can erode enamel.
Practice Mindful Chewing: Chewing fibrous foods not only helps mechanically clean teeth but also stimulates saliva production, which protects against harmful bacteria.
Limit Snacking: Frequent snacking, especially on sugary or starchy foods, keeps your teeth under constant acid attack. Stick to structured meals with balanced macronutrients to reduce the risk of decay.
