Short spoken segment from a YouTube video by Gary Brecka discussing how partially erupted (impacted) wisdom teeth can create a persistent opening in the gum ("leaky gum") that permits oral microbes to enter the body. The speaker links this pathway to finding oral bacteria in the brain (implicated in Alzheimer’s via enzymes that activate microglia) and to more rapid systemic effects in COVID-19 (periodontitis enabling early entry and triggering cytokine storms). Claims are presented as assertions in the spoken narration; citations or supporting data are not provided in this chunk.

Impacted wisdom teeth, they're not generally an issue. However, if they're partially erupted, they're poking out all the time. They become an issue. They're creating an opening to your system. Your gum is outside body. It's like your skin. And you don't want to have these bugs going into your system. If that is poking out constantly, you're creating an opening because the gum is not tight. It's called leaky gum. This is when you find them in the brain of people contributing to Alzheimer's disease because they produce enzymes called guinea pains in the brain, causing microglial cells to get activated wherever you find them. They're not supposed to be in your system and that's the opening. Same for Covid. We know that lurks in the mouth and for some people the cytokine storm just happened sooner. Now we have the research saying if you had periodontitis, that's how they jumped into the system. Not after six days, but straight away and caused the cytokine storm.
