Can Gum Disease Cause Stomach Problems? Unraveling the Connection

Aug 21

Gum disease, or periodontal disease, is a condition that impacts the gums and the structures that support our teeth. The cause of this condition can be attributed to the accumulation of plaque, a sticky film composed of bacteria that forms on the teeth. If one were to neglect the treatment of gum disease, it may result in grave consequences for one's oral health, including the unfortunate loss of teeth.

However, recent studies have suggested that gum disease may have an impact beyond the mouth, perhaps contributing to stomach problems. In this article, we are going to discuss the possible connection between gum disease and stomach problems and can gum disease cause stomach problems. So keep reading!

The Oral-systemic Connection

The correlation between gum disease and stomach problems is a constituent of a growing research delving into the oral-systemic connection. This connection suggests that oral health is closely linked to overall health, and that problems in the mouth can potentially affect other parts of the body. In the instance of gum disease, the bacteria responsible for the infection have the ability to infiltrate the bloodstream and journey to various organs, such as the stomach.

Inflammation and its role in stomach problems

Gum Disease

One of the ways in which gum disease may contribute to stomach problems is by means of inflammation. When the gums become infected, the body's immune response kicks in, thus leading to inflammation. This inflammation may subsequently propagate to various regions of the anatomy, encompassing the gastric region. Chronic inflammation has been associated with various health conditions, including digestive disorders like irritable bowel syndrome (IBS) and gastritis.

The Role of Gut Microbiota

Another conceivable connection between gum and stomach problems lie in the gut microbiota. The gut microbiota pertain to the countless bacteria and other minuscule organisms that reside within the confines of the digestive tract. These minuscule organisms, commonly referred to as microorganisms, possess an utmost significance in upholding the well-being of the gastrointestinal tract. Nevertheless, when the equilibrium of the gut microbiota is disturbed, it may result in a plethora of health complications, encompassing digestive ailments. The bacteria that cause gum disease have the potential to disturb the delicate equilibrium of the gut microbiota, thereby resulting in stomach issues.

Common stomach problems associated with gum disease

Whilst the ongoing research regarding the correlation between gum disease and stomach problems persist, there do exist several stomach problems that have been associated with gum disease. These include:


Gastritis is an ailment that presents itself with the rather unpleasant symptom of inflammation in the lining of the stomach. It may result in symptoms such as abdominal pain, nausea, and vomiting. There are numerous causes of gastritis, such as infection and certain medications. However, it is worth noting that gum disease might also play a role in the development of this condition. The bacteria that cause gum disease have the potential to enter the stomach and provoke an inflammatory response, thus resulting in gastritis.

Gastroesophageal reflux disease (GERD)

GERD, short for Gastroesophageal Reflux Disease, is a rather bothersome condition where the acidic contents of the stomach make their way back up into the esophagus, resulting in unpleasant symptoms like heartburn and the regurgitation of acid. The primary reason behind GERD is a weak lower esophageal sphincter, but it is worth noting that gum disease might also have a part to play. The inflammation caused by gum disease may potentially impact the functioning of the lower esophageal sphincter, resulting in acid reflux and GERD.

Irritable bowel syndrome (IBS)

IBS, also known as Irritable Bowel Syndrome, is a frequently encountered digestive disorder that exhibits symptoms including abdominal pain, bloating, and alterations in bowel habits. Although the precise cause of IBS remains elusive, it is hypothesized to be associated with a confluence of factors, encompassing gut dysbiosis and inflammation. As previously stated, gum disease has the ability to disturb the equilibrium of the gut microbiota and may contribute to inflammation, which could potentially result in the development of IBS.


Frequently Asked Questions (FAQs)

Can infected teeth cause digestive problems?

The symptoms of tooth infections mainly affect the mouth, but if left untreated, these infections can cause problems throughout the body. In certain instances, bacteria originating from an infected tooth might infiltrate the bloodstream and exert an influence upon various bodily regions, including the digestive system.

Can mouth bacteria cause stomach problems?

It is true that specific varieties of pernicious bacteria residing within the oral cavity possess the capability to infiltrate the intricate network of the digestive system, thereby instigating a plethora of gastrointestinal complications.

Can a tooth infection cause diarrhea?

In certain instances, it is possible for a tooth infection to potentially cause diarrhea, although it is not a frequently observed symptom.

What are the signs that an infected tooth is affecting my digestive health?

The indications that an infected tooth is impacting your digestive well-being may encompass enduring digestive predicaments like bloating, stomach ache, diarrhea, or alterations in bowel habits.

Can mouthwash or probiotics help prevent potential stomach problems caused by oral bacteria?

Utilizing mouthwash as a component of a comprehensive oral hygiene regimen has the potential to diminish the abundance of detrimental bacteria residing within the oral cavity. However, it is of utmost importance to select a mouthwash that specifically aims to combat bacteria whilst refraining from disturbing the delicate equilibrium of oral flora.


Whilst the ongoing research regarding the correlation between gum disease and stomach problems persist, there exists an increasing body of evidence to intimate a potential association. Gum disease, which is marked by inflammation and bacterial infection in the mouth, has the potential to cause digestive problems through different ways. These include the bacteria spreading to the stomach and messing up the gut microbiota.

It is of utmost importance to seek early treatment, for it not only aids in the preservation of oral health, but also holds the potential to alleviate stomach ailments. Depending on how bad the gum disease is, professional dental cleaning, antibiotic therapy, and surgical interventions might be needed.
