7 things you should know about the connection between oral health and gut health

Did you know that the health of your mouth and gut are closely connected? The oral cavity is home to diverse bacterial communities that influence more than just your teeth and gums—it serves as a gateway to your entire digestive system. Emerging research reveals that an imbalance in the oral microbiome or inflammation in your mouth can impact gastrointestinal (GI) health in significant ways. In this blog, we’ll explore seven key insights into how your oral health and gut health are intertwined and what you can do to support both.

1.Your mouth is the gateway to your gut.

The bacteria in your mouth can travel to your digestive system. If harmful bacteria overgrow due to poor oral hygiene, they can upset the balance of your gut microbiome, increasing the risk of digestive issues.

2.Inflamed gums can impact more than your teeth.

Conditions like gingivitis and periodontitis trigger inflammation that doesn’t just stay in your mouth—it can spread to the rest of your body, including your gut, contributing to gastrointestinal problems like inflammatory bowel disease (IBD).

3.Harmful mouth bacteria can disrupt your gut’s balance.

Bacteria associated with gum disease can travel to the gut and disrupt its delicate bacterial balance, potentially leading to digestive disorders or conditions like leaky gut syndrome.

4.Oral infections may damage your gut’s protective barrier.

When harmful bacteria from your mouth reach the gut, they can weaken the intestinal lining, increasing its permeability. This can allow toxins and pathogens to enter your bloodstream, worsening inflammation and gut-related health issues.

5.Specific oral bacteria are linked to gut diseases.

Certain bacteria that thrive in an unhealthy mouth are directly associated with gastrointestinal conditions, including colorectal cancer and chronic gut inflammation.

6.Inflammation in your mouth can worsen digestive disorders.

Oral inflammation activates immune responses in your body, which can exacerbate gut issues like Crohn’s disease, ulcerative colitis, or irritable bowel syndrome (IBS). Controlling gum disease may help reduce overall inflammation in your system.

7.Oral hygiene affects your entire body.

Caring for your teeth and gums not only improves your oral health but also reduces the spread of harmful bacteria and inflammation that can negatively affect your gut and immune system. Simple habits like brushing, flossing, and dental checkups are essential for keeping both your mouth and gut healthy.

Dental treatments that can benefit your GI health:

• Treatment for periodontal disease -reduces inflammation and bacteria, preventing gut microbiome disruption.
• Cavity fillings – stops harmful bacteria from spreading to the gut.
• Root canal therapy – removes infection, reducing systemic bacterial impact.
• Orthodontic treatments – aligns teeth for better hygiene and reduced harmful bacteria.
• Dental cleanings – removes plaque and tartar to prevent bacteria affecting the gut.
• Probiotic dental products – supports oral microbiome, positively influencing gut health.
• Oral appliance therapy – improves sleep quality, reducing stress-related gut issues.
• Wisdom tooth removal – eliminates infection sources and chronic inflammation.
• Fluoride treatments – strengthens teeth, minimizing infections impacting digestion.
• Dry mouth treatment – boosts saliva for better digestion and bacterial balance.
• TMJ treatments for grinding and clenching – improves chewing and digestion efficiency.
• Oral cancer screening – detects issues early, preventing systemic health effects.
• Dental sealants – prevents cavities and bacterial infections from spreading.
• Oral infection treatment – eliminates harmful bacteria affecting immune and gut health.

Dentists want you to know: the best protection for your gut is a healthy oral microbiome!

We see Saskatoon patients every day that are surprised to hear that oral health and gut health are so strongly linked to one another. The connection between the oral microbiome, inflammation, and GI health underscores the importance of oral hygiene for overall wellness. Maintaining a healthy oral environment through brushing, flossing, and professional dental care may help prevent systemic inflammation and reduce the risk of gastrointestinal disorders associated with the oral microbiome.
