Your gums are about 60% collagen — the protein that keeps them firm and anchored around each tooth.
After 50, your body makes less of it every year. The scaffolding thins, the tissue loses its grip, and the gum line slowly slips back from the tooth.
That happens even with perfect brushing, because brushing was never the thing holding your gums in place. It cleans the surface. It can't replace what your body has stopped making.
Colla Gum works at the gum line. As you brush, hydrolyzed collagen and minerals reach the tissue directly — giving your gums the raw material they've been running short of.
