"First of all, people who have gum disease doesn't necessarily mean you're gonna have a stroke in the next couple days or couple years. This is an association that's of interest, but it's not something which is highly predictive in stroke, in fact, if you looked at the number of people they surveyed in the one study, they surveyed a lot of people, and you know, certain of them had gum disease, but really none of 'em really developed stroke as far as I understand, and so it's most, the huge majority of people who have gum disease will not have a stroke in the next year, or 10 years, or 20 years. But what this is is a, it's an opportunity to say that if we take care of our bodies, including our mouths, you're more likely to have less health problems, so good oral care is not just important for stroke prevention and maybe heart, but also just overall health."
