A stiff defense: Rethinking gum disease
A section of healthy human gum tissue captured using an imaging technique called Second Harmonic Generation microscopy. In this sample, collagen fibers (shown in yellow), which give healthy gums their firm, resilient stiffness, are dense and well-organized—acting as a supportive scaffold for the surrounding cells (shown in teal).
