Your Gut Health and Your Oral Health 🦷
Updated: Apr 9


The mouth houses a diverse population of microorganisms known as the oral microbiome. The oral microbiome is the second most diverse habitat of the human body, with more than 700 different species of bacteria identified.

There is a link between our gut microbiome and oral health there are trillions of good bacteria living in the digestive system. Your microbiome influences your digestion, immune system, metabolism, and hormones. An imbalance in your microbiome can affect your oral health.

Does microbiome Imbalance affect your mouth?
Gut health has an impact on oral health. If you have too few good bacteria or too many bad bacteria that can turn into harmful ones, this imbalance sends an inflammatory signal to your immune system, causing various symptoms to occur throughout the body—including the mouth. Is recommended that you monitor your dental health by examining your gut health.
Oral Health and "Leaky Gut"
Gut dysbiosis is an imbalance in gut bacteria. Having enough bacteria to keep the gut lining functional and robust. If there is an overgrowth of harmful bacteria that causes inflammation and a leak in the intestinal lining, a number of symptoms can occur, including those that affect your oral health. There are some conditions caused by a theoretical “leaky” gut.
What is "Leaky Gut Syndrome"?
The "leaky gut syndrome" is a hypothetical condition that’s not currently recognized as a medical diagnosis. It’s based on the concept of increased intestinal permeability, which occurs in some gastrointestinal diseases. Read more from the Cleveland Clinic.

Fun Facts
Oral microbiome systemic diseases
Oral microbiome refers to all the bacteria, and their genes, that live in your mouth.
Good oral bacteria means good overall health.
Oral microbiota has been associated with cancer development.
Oral dysbiosis has been associated with cancers of the esophagus, liver, stomach, breast, lung, colon, and rectum.
Not all bacteria are bad: in fact, we need good bacteria to keep our teeth and gums healthy.
Statistics
The oral cavity has the second largest and most diverse microbiota after the gut harboring over 700 species of bacteria.
The oral cavity is constantly exposed to both inhaled and ingested microbes, with more than 700 species comprehensive of bacteria, fungi, viruses, archaea, and protozoans.
The Global Burden of Disease Study 2019 estimated that oral diseases affect close to 3.5 billion people worldwide.
Summary
There is no magic formula for long-term, sustainable weight loss.
Gut health and oral health both matter.
Balance. Portion control. Keep nutrition simple. Eat Smart. Eat Healthily. 🌱 🌾 🌿
Personally
I eat a high-fiber, mostly plant-based 🌱 diet, no red meat, drink 4 liters of water a day, exercise, and am focused on keeping nutrition simple. I am sharing what works for me and what I routinely recommend to my patients.
