Our body is like an intricate and mysterious microcosm. If balance breaks down in even one place, its impact inevitably reaches the entire body. Donguibogam did not view gum and tooth health simply as an isolated problem of the oral cavity. Rather, it considered them a mirror reflecting the state of blood and the qi of the five viscera and six bowels deep within our body. In particular, it viewed the tooth as a part of the bone, observing that when the kidney qi—the zang-fu organ governing bone—weakens, the teeth become loose and fragile.
Here, deficient kidney qi does not merely mean poor kidney function. It refers to a state where our body's fundamental energy, which stores vitality and governs aging, has become depleted. Just as a tree eventually withers no matter how lush its outer leaves are when its roots rot, when kidney qi becomes deficient, the strength firmly supporting the gums and teeth weakens. Furthermore, it explained that when deficiency fire, meaning heat arising because the body is deficient, surges upward, the gums can swell, bleed, and develop severe pain. Just as a fire spreads in an instant across dry ground, when inflammatory heat is added to a state where the body is deficient, gum disease worsens rapidly.
In particular, modern Korean medicine views diabetes as similar to the disease pattern called wasting-thirst (sogal), a state where body fluids dry up and deficiency heat easily arises. In this state, nourishment for the gums becomes insufficient, and as deficiency fire flames upward, the gums are more easily damaged and do not heal well even when inflammation occurs. As the saying goes, 'teeth depend on the gums,' reflecting deep wisdom that the root—the overall health of our entire body—must be firm for the gums and teeth to remain healthy. Therefore, aching gums may not merely be localized pain; it can be a signal that it is time to look back at the overall health state of your body.
