Gut Health and Oral Bone Condition: The 3 Surprising Links


When it comes to oral health, most people focus on brushing, flossing, and visiting their dentist regularly. While these practices are essential, there’s another factor that plays a significant role in maintaining healthy teeth and gums: the gut. Recent research conducted by the National Institute of Dental and Craniofacial Research (NIDCR) has shed light on the intriguing connection between gut health and oral bone health. In this article, we delve into the findings of this study and explore how the gut influences the well-being of our teeth and bones.

The Gut-Oral Bone Health Connection

Understanding the Gut Microbiome

The gut microbiome refers to the trillions of microorganisms residing in our digestive system. These microorganisms, which include bacteria, viruses, fungi, and other microbes, have a profound impact on our overall health. They play a crucial role in digestion, nutrient absorption, immune function, and even mental well-being.

Gut Health and Inflammation

Inflammation is the body’s natural response to injury or infection. However, chronic inflammation can have detrimental effects on various organs, including the oral cavity and bones. Studies have shown that an imbalanced gut microbiome can lead to systemic inflammation, which may contribute to oral diseases and bone loss.

Gut Microbiome and Nutrient Absorption

Proper nutrient absorption is essential for maintaining healthy bones and teeth. The gut microbiome helps break down and extract nutrients from the food we consume, ensuring that our bodies receive the necessary vitamins and minerals. Without a diverse and balanced gut microbiome, nutrient deficiencies may occur, potentially impacting oral and bone health.

The Gut-Oral Bone Health Study

To further understand the link between the gut and oral bone health, researchers at NIDCR conducted a comprehensive study involving both animal models and human subjects. The study aimed to uncover the specific mechanisms through which the gut influences the health of our teeth and bones.

Animal Studies

In animal studies, researchers observed that altering the gut microbiome composition affected bone density and oral health. Mice with a depleted gut microbiome exhibited increased susceptibility to oral infections and showed signs of bone loss. These findings strongly suggested that the gut microbiome plays a crucial role in maintaining oral bone health.

Human Studies

In the human study, participants with chronic periodontitis, a severe gum disease, were examined. The researchers discovered a significant difference in the composition of the gut microbiome between individuals with periodontitis and those with healthy gums. This finding provided further evidence of the connection between oral health and the gut.

Maintaining a Healthy Gut for Better Oral Bone Health

Now that we understand the important role the gut plays in oral bone health, let’s explore some practical steps we can take to promote a healthy gut and, subsequently, improve the well-being of our teeth and bones.

Balanced Diet

Eating a balanced diet is key to nurturing a diverse gut microbiome. Include a variety of fruits, vegetables, whole grains, and lean proteins in your meals. These foods provide essential nutrients that support both gut and oral health.

Probiotics and Prebiotics

Probiotics are live microorganisms that offer health benefits when consumed. Incorporating probiotic-rich foods like yogurt, kefir, sauerkraut, and kimchi into your diet can help maintain a healthy gut microbiome. Additionally, prebiotics, which are dietary fibers that serve as food for beneficial gut bacteria, can be found in foods such as bananas, onions, garlic, and oats.


Staying hydrated is essential for overall health, including the health of your gut. Drinking an adequate amount of water throughout the day helps maintain optimal digestion and supports the proper functioning of your gut microbiome.

Stress Management

Chronic stress can disrupt the balance of your gut microbiome. Engage in stress-reducing activities such as exercise, meditation, or hobbies to promote a healthy gut and oral bone health.


While oral hygiene practices like brushing and flossing are crucial, it’s equally important to recognize the impact of our gut health on the well-being of our teeth and bones. The link between the gut and oral bone health is an exciting area of research, and understanding this connection opens up new avenues for preventive and therapeutic interventions. By nurturing a healthy gut through a balanced diet, probiotics, hydration, and stress management, we can support our oral bone health and overall well-being.
