"Your gums aren't dirty," my hygienist said, nodding at the mouthwash, the gel and the water flosser I'd lined up on her tray. "Your products just can't reach where the infection lives."
"What you're dealing with is a biofilm-protected infection sitting below the gumline. And it happens to most people with stubborn gum disease."
She slid her stool closer, tore a sheet off the pad on the counter and clicked her pen.
"Let me show you what's happening."
She drew a tooth, the gum around it, and a deep pocket in between.
"First, the infection sits at the bottom of the pocket. Your brush and floss stop where the pocket gets deeper than the tool can reach."
"Second, the bacteria have built a sticky biofilm shield around themselves. It acts like a waterproof bunker. Water-based rinses and gels hit it and bead up. They freshen the surface of your mouth, but they never get to the colony underneath."
"And third — this is the part that wears people down — the inflammation never settles. The gum keeps bleeding, swelling and pulling back, so the pocket gets deeper and the bacteria get an even better hiding place."
"Wait," I interrupted. "So all these years of rinsing and Waterpiking, I've been working on a surface the infection isn't even on?"
"Exactly." She tapped the bottom of the pocket with her pen. "That's why it keeps coming back after every cleaning. You can't fix this from the outside."
