Bacteria involved in gum disease linked to increased risk of head and neck cancer
Medical Xpress / NYU Langone Health / JAMA Oncology ^ | Sept. 26, 2024 | Richard Hayes, DDS, MPH, Ph.D. et al

More than a dozen bacterial species among the hundreds that live in people's mouths have been linked to a collective 50% increased chance of developing head and neck squamous cell carcinoma (HNSCC), a new study shows. Some of these microbes had previously been shown to contribute to periodontal disease, serious gum infections that can eat away at the jawbone and the soft tissues that surround teeth.

The new analyses looked at the genetic makeup of oral microbes collected from healthy men and women. Of the hundreds of different bacteria that are routinely found in the mouth, 13 species were shown to either raise or lower risk of HNSCC.

Overall, this group was linked to a 30% greater likelihood of developing the cancers. In combination with five other species that are often seen in gum disease, the overall risk was increased by 50%.

For the research, the team analyzed data from three ongoing investigations tracking 159,840 Americans from across the country to better understand how diet, lifestyle, medical history, and many other factors are involved in cancer.

Shortly after enrolling, participants rinsed with mouthwash, providing saliva samples that preserved the numbers and species of microbes for testing. Researchers then followed up for roughly 10 to 15 years to record any presence of tumors.

The investigators analyzed bacterial and fungal DNA from the spit samples. Then, they identified 236 patients who were diagnosed with HNSCC and compared the DNA of their oral microbes with that of 458 randomly selected study subjects who had remained cancer-free. In their research, the team accounted for factors known to play a role, such as age, race, and how often they smoked cigarettes or drank alcohol.

"Our results offer yet another reason to keep up good oral-hygiene habits," said study co-senior author Richard Hayes, DDS, MPH, Ph.D.

It appears possible good oral hygiene could prevent dangerous head and neck cancers, which are usually worse than other locations for cancer.

From May, possibly related, just the abstract unfortunately...

Effects of post-COVID-19 vaccination in oral cavity: a systematic review

The kicker...

...Immune-mediated oral events have a propensity of occurrence following COVID-19 vaccination. mRNA-based vaccinations may have an affinity for causing oral adverse effects. It might be due to the immune dysregulation caused by these vaccinations...

Looks like CoupFlu vaxxes don't just screw with the gut biome.

I’ve read that spirochetes (I assume a type of bacteria) that often are in the mouth, maybe they help with making cavities? Can’t remember what I read; also contribute to Alzheimers.

Last dentist I went to did a test for bacteria count in the mouth. He was astounded that I had none. Zero. He asked what I brushed my teeth with, answer: baking soda. He said it kills spirochetes in the mouth, maybe other bacteria as well. I alternate with home made tooth powder.
