It's unsurprising that certain strains would lead to increased cancer risk. We've known about this with bacteria (H. Pylori and stomach cancer), viruses (HPV and genital cancers) and fungi (carcinogenic liver toxins) for a long time. But I do somewhat wonder about the dental profession's "nuke it all" approach to the oral microbiome. We've largely moved away from that for other outside-facing body parts - it's recognised that for organs like skin, gut, vagina, scalp etc that there is such a thing as a healthy, balanced microbiome. I expect they'll get around to discovering the same for the mouth at some point - that if you have the right bacteria and don't overfeed them with massive amounts of glucose and fructose, that's broadly a healthier mouth than blasting everything to oblivion at every opportunity.
