Current research indicates gum disease is a cofactor in causing cancer. This means that it creates an environment that makes it easier for cancer to develop.
The link between gum disease and cancer is defined by chronic inflammation and the presence of bacteria that facilitate tumor growth. Recent research reports that Periodontitis is associated with an increased risk of chronic systemic conditions such as autoimmune diseases and different cancers [1] (Irani et al 2020). Novel technologies, including new saliva tests, can identify high-risk bacteria before they cause damage. Treating periodontitis is a proactive way to reduce your risk of cancer. Our team, Enamel Dentistry at The Grove in Rosedale, encourages you to protect your oral health by better understanding the link between gum disease and cancer
Dentists have suspected a connection between gum disease and head and neck cancer for years. Recent research supports that 13 species of bacteria carry the risk of head and neck cancer [2] (“Bacteria Involved in Gum Disease Linked to Increased Risk of Head & Neck Cancer”). In fact, those who have never smoked can be at risk if their oral health has been compromised. The link appears to be periodontitis, which ultimately damages gum tissue and destroys the bone that supports teeth. When left unchecked, it creates a constant state of inflammatory stress.
The answer to this question lies in two factors: inflammation and infiltration.
Modern dental technology can now use salivary diagnostics to screen for cavities and gum disease. This breakthrough technology has shown promise in diagnosing and monitoring systemic conditions [3] (Albagieh et al., 2025). A saliva sample allows the lab to measure oral bacteria levels and genetic markers linked to inflammation. Early signs of viral infections can also be detected, and in specific cases of H. pylori, which is linked to throat cancers. This allows our dentists here at Enamel Dentistry the Grove in Rosedale, to treat the cause of the disease, not your symptoms.
Below is a table comparing treatments in terms of benefits, recovery time, and cost.
Feature | Routine Cleaning | Periodontal therapy | Untreated |
Goal | Polish teeth to remove plaque | Remove bacteria | N/A |
Systemic benefit | Low | High | Negative |
Pain | None | Minimal | High |
Recovery | immediate | 24-48 hours | N/A |
Cost | Covered by most insurances | Moderate | High |
Reducing the amount of bacteria and stopping inflammation in your mouth can reduce the main stressor to your immune system. By undergoing periodontal therapies, inflammation can be lowered in the body. Research has shown that Fusobacterium nucleatum can hide within tumor cells and protect them. Professional scaling can remove these bacterial colonies, inhibiting them from traveling to other parts of the body. By healing gum tissue, it turns off the inflammatory proteins that harm DNA and stall tumor growth. While treatment is not a cure for cancer, it does remove the main biological stressor.
At your next appointment at Enamel Dentistry, the Grove in Rosedale, ask these three critical questions:
Current research indicates gum disease is a cofactor in causing cancer. This means that it creates an environment that makes it easier for cancer to develop.
Modern therapies have become much less invasive than in the past. Local anesthetics are used with laser technology. Most patients report little to no discomfort and can return to their normal lifestyle after 24 hours.
Two questions you should ask your dentist are: What is the depth of my pockets? Also, can a salivary test be done for bacteria?
