Barrington Smiles Dental Hygienist: Donna Grzegorek Shares research on the Connection between Gum disease bacteria and stomach Cancer

Most people know that gum disease (periodontal disease) can affect their oral health, leading to bleeding gums, loose teeth, and even tooth loss. What many don’t realize is that the bacteria that cause gum disease don’t stay confined to the mouth—they can travel through the bloodstream and impact overall health in surprising ways.

The industry is aware that periodontal bacteria have been linked to diabetes, heart disease, strokes, pancreatic cancer, colon cancer, Alzheimer’s, Parkinson’s and pre-term low birth weight babies.

Recent scientific studies have revealed a concerning link between certain periodontal pathogens (harmful bacteria found in gum disease) and an increased risk of stomach cancer. Researchers have discovered that people with advanced gum disease often carry higher levels of bacteria such as Fusobacterium nucleatum and Porphyromonas gingivalis. These bacteria don’t just damage gum tissue—they may also influence inflammation and changes in cells that increase cancer risk in the stomach.

Why does this matter to you?


  • Gum disease is one of the most common chronic infections worldwide, often painless in its early stages.
  • The bacteria associated with gum disease can enter the bloodstream and travel to distant organs, including the stomach.
  • Studies suggest that people with untreated gum disease may be more vulnerable to serious conditions, including stomach cancer.


The good news: Gum disease is preventable and treatable. Daily brushing, flossing and mouthwash use, combined with professional dental cleanings and exams, are your best defense. By controlling oral bacteria, you’re not just protecting your smile—you’re also reducing risks to your overall health.


Takeaway: Healthy gums are more than a cosmetic concern; they are an important part of a healthy body. If you’ve noticed bleeding gums, persistent bad breath, or changes in your bite, don’t wait—schedule a dental evaluation. Early action could protect both your smile and your long-term health.

Despite their similarities in appearance and symptoms, they have distinct causes, treatments, and implications. This guide will delve into the differences and similarities between these conditions, helping you identify and manage them effectively. Canker Sores Canker sores, also known as aphthous ulcers, are small, painful lesions that develop inside the mouth, typically on the soft tissues such as the inner cheeks, lips, and tongue. They are not contagious and usually heal on their own within one to two weeks. Causes The exact cause of canker sores is not fully understood, but several factors are believed to contribute to their development: Stress and hormonal fluctuations Injury to the mouth (e.g., biting the cheek, dental work) Food sensitivities (e.g., acidic or spicy foods) Nutritional deficiencies (e.g., iron, vitamin B12) Underlying health conditions (e.g., autoimmune disorders) Symptoms Canker sores are characterized by: Round or oval-shaped lesions with a white or yellow center and a red border Burning or tingling sensation before the appearance of the sore Pain and discomfort, particularly when eating, drinking, or speaking Treatment While canker sores usually heal on their own, treatment can help alleviate pain and speed up the healing process: Over-the-counter topical ointments and gels Antimicrobial mouthwashes- like Listerine Prescription medications for severe cases Avoiding trigger foods and maintaining good oral hygiene Aphthous Ulcers Aphthous ulcers, often used interchangeably with canker sores, are a specific type of canker sore. They share the same characteristics, causes, symptoms, and treatments as canker sores mentioned above.
