Does a tooth-marked tongue indicate spleen deficiency or spleen dampness?

Sometimes, when we look at our tongue in the mirror, we notice tooth marks along its edges and suspect they may be caused by Spleen deficiency or Dampness accumulation in the Spleen. So, are tooth marks on the tongue due to Spleen deficiency or Spleen-Dampness?

Are tooth marks on the tongue caused by Spleen deficiency or Spleen-Dampness?

Tooth marks on the tongue reflect both Spleen deficiency and excessive Dampness—two interrelated pathological conditions. Specifically, tooth marks arise when Dampness accumulates on the tongue, causing the tongue body to become enlarged and swollen, thereby becoming compressed by the teeth. A soft, edematous tongue is quite common and primarily results from Spleen deficiency impairing the transformation and transportation of fluids, leading to Dampness stagnation on the tongue.

Clinically, this presentation is very common and is mainly attributable to Spleen-Yang deficiency resulting in excessive Dampness. Recommended management includes regular physical exercise, avoiding cold and raw foods, consuming spleen-strengthening foods, and using appropriate Chinese patent medicines—all of which yield excellent therapeutic outcomes. Moreover, Spleen deficiency and Dampness accumulation are mutually reinforcing: Spleen deficiency impairs the Spleen’s primary function of transformation and transportation—including its role in metabolizing food and fluids. When Spleen Qi is weakened, internal Dampness accumulates, causing the tongue to swell and enlarge. Thus, Spleen deficiency and Dampness accumulation often coexist. In addition to tongue signs, diagnosis must also consider systemic symptoms to determine whether the patient predominantly exhibits Spleen deficiency, Dampness excess, or a combination thereof.

Additionally, if such symptoms appear, it is advisable to seek prompt medical evaluation at a hospital and follow professional guidance for appropriate management. We hope this explanation proves helpful!
